well ive been workin on the car and that dame check engine finally is getting to me. i check it out and it comes out to be 54..check it out on alldata and it says something like p1 squib line to p2 squib line.. asking around its something about the air bag?? wiring harness was made by dr.tweak and i am sure i put the engine in right. just cant seem to get rid of the dame code..anyone have a clue help please.

yeah im runnin a front mount right now. i think i bridge the connection together correctly. now the problem is the did i bridge the right one. the only plug that doesnt have a male connection only has a black/yellow and a yellow/blue wire. i think the one that goes to the intercooler has three wires. i now also see that i need to get a new evp sensor cause i just have two expose wires just sitting there. but the code is still 54 so im still tryin to figure out where tweak placed the coolant lvl sensor plug..?
