So I just bought an 86 Z28 (LG4, 700r4), and one of the previous owners converted it to non-cc q-jet ad distributor, so it got me thinking about TC lockup, since the ECM is disconnected. Since it's an 86, it SHOULD still have a NC 4th gear Press Sw (please correct me if need be). So, if this is the case, I came up with a method for TC lockup without dropping the trans pan for those of us who may not want to mess with it.

Here's the diagram I came up with for anyone else who may be interested. This can be added to existing info found here on TGO; sorry, I don't have the other wiring info sitting right here, and time is a little short for me as of late, but if anyone wants to add to this (links, etc), feel free. You should be able to do this with existing harness parts, a pressure switch (Normally closed), and a Normally closed relay. Hope this helps!

If you swap the NC 4th gear switch for a NO version you don't need the relay.
TCC will engage any time trans goes into 4th

Yep, I've gone over all that before; Just figured I'd post another method for those who don't want to drop the pan for whatever reason. Better too much info, even if it's never used.
