im in the process of goin from a tbi to a steath ram in a 92 rs i got a harness from a 92 z-28 for the wiring the problem im having is i have a wide flat 4 plug that i cant seem to find where it goes its wired into the distributor and coil im lost any help??...or a link to a good wiring diagram

 

You should have two connectors to your dist (actually the ignition module.) One goes to the coil (three pin) and the other goes to the ECM (four pin.) You should have two connectors to your coil. One is from the dist (again, three pin) and the other is from the ignition switch/instruments (2 pin.) Good luck with the swap!

 

I tried to find out where the four wire connector terminates to the ECM but I guess Haynes doesn't know either, sorry!
