No A/C after f.a.s.t hook up (???)

[scot w.]

First of all iv'e got the digital dash / Elec. touch climate control. I recently installed my F.a.s.t b2b system with the older PTE jumper harness. Well everything else works fine, just the A/C isn't kicking in. Iv'e already got the low pressure switch jumped out due to a leaking switch so it's capped off and jumped out. It was blowing very cold air before the f.a.s.t hook up. any tips would be greatly appreciated. Thank you! Scot w

Darn,I dont recall but there is a single wire in your factory ecm harness that needs to be grounded and it will work.
