swapping 7730/406 tpi to 94 firebird. which wires on harness need energized/grounded
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..
