Hey, scrub here, first time ls swapping and I'm trying to pick a pcm. I'm putting an lq4 in a mustang, I have the running gear out of an 01 yukon Denali. The pcm I have is Serv no 12200411 hdw no 09386530 which lucky for me is an IAC pcm(did no research before I hit u-pull-it). Im putting a fuel system together and don't know why I wouldn't just set this up for e85 but as far as I can tell the pre03 pcms can't drive a flex sensor. So my question is what are my options for e85? I need a 24x pcm with IAC and flex and ideally I'd like to retain my red/blue harness(just because I've already stripped it to it's essentials) but I am aware that might not be possible. (not really sure what the difference is between color connectors) I've done a bit of googling but still don't have an answer.
