I'm converting my 93 lt1 into a 94. I got a 94 harness, and need to know if it makes a diff. what wire goes to what injector.
Merry christmas

I do not know of a difference. they should be the same. the pink wire is the fused hot feed and the grenn wire is the PCM ground pulse....

 

There is a huge difference. The 93 is batch fired and the 94 is sequential. There are inumeral changes that go with it. 94s have a MAF that 93s don't and obviously programming differences. In the 93's the wiring between banks for the injectors doesn't matter, in the 94 and up each injector must be wired correctly. This is not something the average person can accomplish.

 

I really hope a 93 comes into the shop one day. I need to spend some time poking around one. I have yet to work on a speed density Fbody.

 

You should have put this on www.speeddensity.org I would have seen it alot earlier. I can send you the diagrams from the 93 and a 95, the same as a 94. Dont be a stranger now!

 

I know there is alot involved into the swap. I already have the 94 (comp., harness, mass air, heated o2s, ect) I was just wondering if there was someway to find out which injector wire goes with which injector. When i took off my 93 harness i labled everything. Not so lucky with the new 94 haarness though.

I just learned this, but there is big white numbers on each harness that tells with injector it goes to.

 

So true .

 

THANK YOU..
So # 8 on the harness would go to #8 cylinder, or injector or does it matter.
Thanks again guys i was really sweating this.
