ok, so not exactly an f-body but follow along for a minute. this was the best place to go when i was tuning PROM's, so here i come back.

i am installing an 89 c1500 engine and tbi setup in my pro-touring, daily driven, 64 el camino. while doing so, i want to do what the ricers would call a wire tuck. or hide the wires, or whatever you guys want to call it. just a nice, neat, clean installation.

in my state, i do not have inspection. so emissions syuff can be deleted. but for the sake of fuel economy and some emissions compliance, i am retaing at least the egr setup. other than the ultimate tbi mods, a true cowl plenum air cleaner, 2 1/2 exhaust with high flow cats and an x-pipe, and a set of 1.6 rockers, the engine will remain stock.

what i want to do, is make it as visually clean and appealing as possible. wiring harness to the ecm will be run through the trans tunnel. all the rest of the harness will be shortened or rerouted as necessarry for proper operation and cleanest looks.

looking at the engine, it has the esc, some vacuum solenoid, and the coil all mounted to the intake. those are kind of ugly. the air injection setup is already in the scrap metal bin, along with the fullsize accessory drive. using the accessory drive from a vortec blazer (was on the carb'd engine). i have a large cap HEI from a TPI corvette that i would like to use, thereby eliminating the remote mount coil. what do i need to do to utilize it on a tbi setup? im assuming swap the module and wiring over, but after that...

also, the TPI cars had the ECS up on the firewall, as well as the tbi s10's. any reason i cant do that on this engine?

other than the egr valve itself, and the vacuum hoses for it, any emissions equipment i should retain, and why? the EGR will stay, even though i could tune it out. it does help, and enables me to run lean cruise in the ecm programming.

lastly, anyone have any good pictures of a good, detailed, visually cleaned up tbi underhood? ive googled it every which way i can think of for all these questions, and just come up with nothing.

thanks

I put an 87 TBI truck motor in my 71 truck, and wanted to do the same thing with wiring as you. I did get rid of the EGR, though. I'll see if I have a picture when I get home.

here you go. start and finish. have egr but all the rest of the emissions is gone.

can I talk you into some detail of what exactly engine wise you did to get there? especially the egr stuff?

EGR does not contribute to MPG, actually introducing exhaust gases to the intake does the exact opposite. You can't just unplug and forget since it will trip a code in the computer, I believe there are work arounds listed in one of the stickies (I know there used to be, I think JPrevost wrote it up)

Wire tucking is time consuming but the results can be fantastic as One92RS shows. Good luck with the project and keep us up to date on your progress.

sure send me a pm. will be glad to answer any questions. gained 2 mpg with the egr hooked up and working properly. no a/c and getting 22 to 23 mpg on highway.
