So Im getting ready to ship my wiring harness to Speartech. I have a LS1 out of an 04 GTO going into my 91 mustang and need to see if anyone knows what to have removed from the wiring harness. I do want to keep the a/c just in case i decide to put one in. I have no idea what emmisions stuff I can removed and still pass an emissions test. Does anyone have any info on what can be removed from the harness?

 

Anyone?

 

Oh good luck man, I dread the day I start the wiring on my ls swap.

 

Look at the sticky / FAQ at the top, though your 94 GTO might not be there as a Pin-Out.. there is some pertty detailed information on what is 1) required, 2) optional and 3) not needed for the one you see listed. The same type of modification would be the same for your 04 GTO wiring..

Then again, if your using Speartec. just call John and he will work with you in the 1st place.

 

Thanks man!! I completely forgot about those pin-outs. I'll give them a shot and see whats needed.
