under my bonnet glad you are having fun. but do u have a serious answer? you must need a compressor wiring loom if you ain't got the connection,cause you ain't got a proper compressor so it's not their! allrite but what i wonder is where does this AM300-12500 cable end? (u can see the part on compressor part list pdf on page 5) look i guess i better send photos or smt like that to explain my problem. my english is good but i dont know all those electronic and automotive terms so should i upload photos?
