ls1 swap wiring harness

[badinfluence]

i have been reading that in order to swap a ls1 into another non-lsx vehicle you need to modify the wiring harness.

why?

if you have a complete donor car, couldnt you just swap everything over to get it running? no need to ac, cruise, etc

you may throw codes if some stuff is disconnected?

[badinfluence]

dont care about codes as long as it runs good. i throw codes as-is anyways (!EGR, !cats)

you should be fine

[badinfluence]

thats what i thought.

only things im not sure about is gauges & igntion cylinder. i could re-use the key easy but i wouldnt want 4th gen gauges

[Virtue]

what are you putting it in

[badinfluence]

it would be a 2nd gen
