I bought an 85mm MAF off an 03 truck. I want to adapt it to my Trans Am...I bought the Caspers adapter but the MAF plug in is wrong everything else works on the adapter. The wire colors are different and I want to know which wires goes where? I want to repin or solder the truck plug in on the caspers adapter. Here are the pics....
