If anyone does not know I totaled my once beautiful 10 second 87 trans am - decided to pick up a 94 v6 firebird as a trans plant car for my 406/t56 combo that was converted from 265 - 7730 ecm - probably a backward swap - but still a good engine..
Anyway just pulled harness from trans-am, noticed there are (3) connectors split off of ecm harness to under dash - one connector is a,b,c,d,e,f,g,h,
other side is j,k,l(not used),m,n,p,r. the a small 6 pin that uses A,C,D,..

mY Question is, are any of these wires needed? if so which ones..
Basically what pins must I ground,power,ign power to energize this thing in the car..

Will also post on engine swap board..

you might wanna try the diy prom board... all kinds of pin out diagrams and stuff floating around there...

406 tpi? i'm putting together a tbi swap - what did you use for your knock sensor, the 350 unit? any problems with false knock counts?

 

Thanks,
I have pinout diagrams, but the connector for under dash is split off ecm harness, just figured someone would know off hand..

No problems with knock prior - but I disabled that a long time ago for racing consistancy via prom..
