Harness question
Hey TGO Team...
I have a question... Do I need to swap harness from a 1991 formula into my 92 305 LB9 vert? I have a chance to buy a 5.7 engine and rear from the same 91 formula. The harness was partially cut from the craigslist ad pics.
Will my harness work by just plugging my male end of the harness already in my car into the female end of the the 91 formula's ecm/prom? Then drive all the right parts when I swap the formula 5.7? Or are there differences in anything, like firing order or something that you wouldn't find out until after all the swap is done... You know the frustrating times!
Would like as much plug and play as possible. I would prefer to not cut and splice harnesses to make it work. What do you guys think?

There shouldn't be any differences between the 305 and 350 harnesses from those years. You mentioned T5 in your other thread, that would be the only difference.
Unplug the 305 harness from the 305, unplug the 350 stuff and set aside, plug your 305 harness to the 350.
