This an email I sent Allen...I was wondering if you guys had an answer as well
"Hey Allen its Aggie off LS1 truck...He I just ordered my E Fans today...I have the 4.3 as you know...and Im going to a 6.0 really soon...Im getting it from TRT performance...I was wondering if its possibly you can make a harness that will transfer over or that I can leave on during the swap process....Or does it matter on what engine you have? Will I need my PCM flashed?"
