need help here, first off what Im dealing with is a wiring harness from a 1987 gta 350 trans am that I put in my 1982 trans am, I get a consistant code 33and Im ready to say to heck with the maf system and run a painless speed density setup I have, here is the maf I'm using bosche 0 280 213 004 14 094 712, is this the correct one for a 1987 ? Ive read on power to the maf plug when I jump terminal G (I think) I get power to my red wire on the maf plug, and while the car is running it also has power, however I can never get power to the blue wire no matter what I do, can any one tell me exactely which relays are for power and burn-off by wire colors since mine arent in the same location so a picture won't help me much, Ive traced most of the wires and none seem damaged, I've tried two ecm's and two USED mafs without any improvement, is this a definate maf problem or simple wiring issue, I don't especially feel like spending two hundred bucks for nothing, or is anyone in southern california that can help me straighten this problem out

 

don't respond, gave up on mass air flow and re-pinned my harness to run speed density ...... MAF a 3 letter word for trouble
