I don't know what I'm doing wrong but this POS wont work for the life of me.
Purchased JB4, opened hood, locked car, relocated key fob somewhere on the other side of the universe. Disconnected factory harness, connected JB4, turned car on, 16 different check engine and warning lights. Shut off car, disconnected harness, swapped said harnesses, turned on car, no lights but car drives like sh*t, no power, no nothing. Disconnected unit completely, now I have a Check Engine Light.
How am I screwing something so simple up?
