I've been reading through the forums for a little while but this is my first post so what's up guys/girls? I have an 86 iroc z with 350 tpi and 700r4 tranny that I got into an accident with and bent the unibody. I bought a 92 camaro rs with a v6 and 5 speed tranny. I'm in the process of swapping the 350 and 700r4 into the 92 rs but am a little confused about the wire harness and ecu. I know i have all of the parts i need because of the full donor car i just dont know how much of the wiring must be transferred over. I would imagine i need the wire harness from firewall to engine (from the 86 with 350) and ecu. What about the wires to the headlights, dash and all that? What about all the wiring under the dash inside the car though? All help is highly appreciated!

edit: I have read through a ton of swap threads already but i just haven't found a clear answer. I can take pics if needed. Also the 86 doesn't have a/c and the 92 does, what would it take to keep the a/c?

Anyone? Please feel free to direct me to a DETAILED thread if there is one. I haven't had any luck finding what i'm exactly looking for. The sticky is a little vague to me as well so it won't do. Also can anyone tell me what these connectors go to? They were unplugged when i bought the car and i'm sure the PO deleted what they plugged into.

As far as your swap goes you might be better off bye getting a 86-87 harness for a a/c car. The headlight part of c100 can remain with the 92. You may need to make changes to c201 as well. you will need to compare the pinouts. The 86 has a cable drive speedometer. Are you going to swap over the cluster ? If not that's were you will be spending some money to get the speedometer to work. The easiest would be to buy a vss sensor and Dakota digital sgi-5 to be able to feed the Ic a 4k optical signal.

Ok so the vss sensor and the Dakota digital sgi-5 would be all I needed to get the 92 cluster to work? I'd rather keep the 92 cluster if possible. A/c isn't a big deal for me I can do without, that being said will the wire harness I have now off my 86 work fine? Ill have to swap the ECM over from my 86 as well won't I?

The vss sensor and the Dakota would be just to get the 92 speedometer to work .
there is another way but may end up being a cluster. The v6 had a 1227730 ecm with a speed sensor buffer built into it. You can piggyback it and use it for a the speedometer signal and to feed a 2k optical signal to the 1227165 ecm from the 86. You need a vss signal to the ecm regardless. Tpi parts has a 2k retrofit sensor that can go directly to your 86 ecm. This will allow the ecm to control the iac and tcc lockup.

Another option is the 90-92 retrofit vss hooked to a vss buffer. this would hook to the ecm and speedometer. the bad it may not be correct calibration then the purchase of the sgi-5 would be needed.

There is a ecm and harness in the classifieds for sale for speed density. You would still need the 4k ppm retrofit vss but your speedometer would work in the 92.

its has vats enabled so that would have to be reprogramed out or bypassed.

Formula 305

Wouldn't he want the V8 cluster anyway? Wouldn't the V6 tach not function properly with the V8 engine?

UberFast

iTrader: (1)

Ok thanks for the help so far guys. Now I'm guessing the only way to know if the vss buffer is calibrated or not is by hooking it up and seeing what my speedo says? Would the easiest thing to do be just swapping my 86 cluster into the 92? Will the cluster seperate from the dash or does the whole dash have to be swapped? Remember I have an entire parts car so I could turn this whole 92 into an 86 if I wanted to, I'm just looking for the most feasible thing to do.

UberFast

iTrader: (1)

I'm guessing that's what tuned was getting at when he said just the speedo would work with the above mod. The PO installed an aftermarket sunpro tach in my 86 as well because the factory tach quit working on him. I don't know if that helps or not, I don't think I could swap that tach in because it would be getting its signal from the same source correct?

Formula 305

An aftermarket tach would defiantly fix the issue yes. I think all the other gauges should work fine besides the tach. I believe oil pressure, temp, volts, & fuel is all referenced directly off the sensors

UberFast

iTrader: (1)

Ok would it be easier to swap the dashes out? I don't think the clusters will interchange due to shape differences. I'm trying to do this as cheap as possible using what I have. If I were to swap the dashes and clusters would there be any wire changes then?

iTrader: (4)

if you get the harness that tuned linked, it will be way easier. i have taken an '87 tpi and put into a '91 camaro. get the harness linked. then get a factory 90-92 vss for the camaros which were gear driven and will slide in place of the current speedo bullet. get a map, tps, and knock sensor for the 90-92 v8 tpi and you should be good to go if you use that aftermarket tach.

i also put a '92 dash into a '89 and the mounting points were slightly different. ended up being a pita

UberFast

iTrader: (1)

My 350 tpi is maf. Does that make a difference?

87zjeff

iTrader: (4)

no, this is why you need the MAP sensor. the speed density uses it instead of the MAF.

UberFast

iTrader: (1)

Ok so that 92 wire harness that tuned linked wont even have a connector for the maf sensor? All I would have to do is remove my maf sensor and install a map sensor from a 92 instead? Where does the map sensor go on the engine? Is there a place on my engine for it? Sorry for all the noob questions, just trying to make things as clear as possible for anyone else that has my same problems.

87zjeff

iTrader: (4)

nope, no connector for it. i mounted my MAP sensor to the cowl right above the AC box. this afforded a convenient mounting point that left the hose from it to the intake fairly short.

UberFast

iTrader: (1)

The map sensor needs a source of vacuum correct? Does it have to be from the intake? Where on the intake? When I switch to map what ecm do I use? The ECM that comes with that 92 harness?

UberFast

iTrader: (1)

OK so let me get this all together.

What I need:
90-92 350 tpi harness and ecm
92 vss sensor
Dakota digital sgi-5

With the above listed, would there still need to be some wiring changes?

Thanks again guys y'all are being a HUGE help!
92 tpi map, tps and knock sensors

You will only need the Dakota digital if your transmission drive and driven gears for the speedometer do not match the rear end and tire size ratio. The map sensor does need manifold vacuum and not tied into anything else. Youe plenum has two ports on the rh side hvac/cruise , fpr, you can allways tap a 1/4 npt hole I have the measurement on another thread if needed. Or buy a ninth injector block off kit and tap the ninth injector plug and install a nipple for the map. For the tach calibration Greg has a service for $35 in the classified section.

You need to compare the schematic of c100 it maybe the same. Hope all this info makes since . If you miss out on the harness and don't need emissions there is a new harness on ebay for $260 and I can assist with the memcal and programing? You can use the v6 ecm with a different memcal

87zjeff

iTrader: (4)

as long as the harness is from a camaro it should plug right up with no issues. when i did mine i got my harness from a '90 firebird which had one wire in the c100 and one wire in the c207 that was different. however, as tuned stated, best to get the diagrams and be 100% positive. the only other wiring i can think of you might need to change is the alternator and AC(if used) wiring due to them being on different sides of the motor between '86 and '92. '86 alternator was on passenger side of motor and i believe '92 was on drivers side.

Alright thanks guys. Which of these two would y'all recommend? Cheapest? I'm not sure what the ostrich 2.0 is.

i'm not familiar with the ostrich either. i used the nvsram in mine. i still have the ecm that has it installed that i am going to sell eventually. if it were me i would get the one with the factory harness and ecm. the other looks to have wires that need to be spliced in.

Alright ill try to win the auction for the factory harness. Can someone post a link to exactly what i would need to get my aftermarket tach to work with this setup? Start off with the vss and if I need it the Dakota?

Tuned Performance

iTrader: (92)

You got it start with the vss and get the Dakota if the speedo needs corrected. Talk to Greg about the tach. Its just the small module that needs to be sent in.

Hey tuned would the same go for my aftermarket sunpro tach? As far as sending it off to greg? Or is that just for the factory tach?

Tuned Performance

iTrader: (92)

Sun pros have a switch to change from 4,6,8 the factory tach is on a little board you can take off the bezel and clear cover. It is in the rh bottom corner and just pulls out.

Alright. Hey that 92 harness and ECM you linked earlier. I'm trying to buy it. Am I going to have to send that ECM off to get it programmed or unlocked or anything like that? Or will it be plug n play?

vetteoz

iTrader: (13)

A particular ECM may be used for many different cars/ engines.
All you need is a memcal (chip ) programmed for whatever you have.
See TP for tuning

vetteoz

iTrader: (13)

The Ostrich is the ultimate in ECM programming.
Allow you to make tune adjustments (even as you drive ) without having to remove and reprogram the chip

Can be solved

The description for that harness and ECM say for a 5.7 tpi. Would it still need to be tuned for my 5.7 tpi?

UberFast

iTrader: (1)

What about VATS? Is that going to be a problem?

Tuned Performance

iTrader: (92)

The memcal will work with the programing but it needs the vats bypassed. A few ways around disabling the passkey.

You know a guy lol. What's your turnaround normally? Would I also need a tune? My engine supposedly has notch top pistons, roller cam(.510 lift) and lifters, and flat tappet valves. I bought it the way it is so I don't know exactly what all is done but it does have some pep to it.

Tuned Performance

iTrader: (92)

My turnaround is next day mon-Thursdays . Some weekends I head to the mountains for the weekend. Do you know your cam duration , aluminum or cast iron heads, would you like emissions disabled ? Anything over stock can improve with tune. But I need to establish a base tune and have a datalog to refine the calibration. If you were running a stock memcal before apples to apples.

UberFast

iTrader: (1)

No I don't know the duration. I'm pretty sure they're cast iron heads but I haven't checked anything on it really and yea screw emissions lol

Hey I'm about to order some parts for the swap but which vss do I need? Do I need the one tuned linked earlier or can I just use a factory 92 vss?

87zjeff

iTrader: (4)

if you are using the '92 cluster, just get a factory vss for a '92 camaro

UberFast

iTrader: (1)

Alright sweet, yeah I'm using the 92 cluster. Also what's the difference between the knock sensors? Why is it I need a 92 knock sensor?

87zjeff

iTrader: (4)

when i did my swap, i found info on here that the knock sensors were different. i'm not positive what the difference is.

UberFast

iTrader: (1)

I couldn't find anything describing their difference either but ill get a new one anyway. The 92 is almost ready for paint and then ill be pulling the engine and tranny from my 86 to drop in.

Tuned Performance

iTrader: (92)

The 90-92 speed density uses a 3.9k ks, tpi maf uses a 100 ohm resister. The ecm will do a forced knock test. If it doesn't fee the correct voltage due to resistance difference it will fail and go into lhm.
