I just bought this truck about a month ago and it has a couple of mods. My only problem is that there are two wires that came off of the mass air conversion harness and since they are all black wires I can't seen to find were they go. Does any body have schematics for the harness. I sure do appreciate any help.
I was just cruising the net for Lightning conversions and found this post.
You may want to check over at fordfuelinjection.com (just Ford FI info, but tons of it and they sell some pieces/parts for EFI conversions) for some info.
Fordfuelinjection has a instructions posted for a generic EFI swap made by Ford gonna have to search though.
What processor is with the kit? This may help you figure out which kit you have. There aren't many conversion kits and I just got my L last year so haven't been in the loop for long, just Mustangs.
Blurry94 may well be right since it wouldn't matter which way a ACT was wired, but it should have a connector on it. You should also have wiring going to 2 O2's also (stock SD Lightnings only have one O2)
