Plug and Play 1228062 swap to 1227747 A/C Issue

[S.O.B.B.]

Hello there.I swapped the 5.0l 7747 in place of 7429.a few wires didn't match.the ac was one.A2 on 7747 said not used.on tge 7429 the A2 and B8 both go to ac.not sure about which wire does what as my ac never worked so I left that wire out.as for the wipers I don't see what in the ecm harness goes to the wipers.I do have schematics for 7429 and 7747 to compare if it would help.the other thing different was egr related for evrv or egr solenoid. Also etm for hot fuel if I remember correctly had a difference also.I have my harness plug in view if a compare is needed.if i recall the ac going to B8 on 7747 is just for iac idle increase with ac on.if i can get into my garage i can check notes later today after work.nice ice storm here so I don't know if I'll get the door open .hth
