first off, my car IS mass air converted via a fms conversion. it is working fine, except for my speed density (stock harness) is screwed up. some of the wires are cut going into the computer, some of the pins fall off the computer, ect.

i have bought 3 speed density harnesses from private people online, and NONE of them are right. the connectors dont match my car, and each of the three has been different. so i know its not just my car having a unique harness.

im wondering if painless wiring or any company makes a replacement wiring harness that im sure will fit? 50resto is down now, and im not seeing much on painless' site, besides the one for 89+ cars. figured some of you wiring guru's would have good input.

also, before someone suggests just buying a mass air harness. i tried two of those conversions before i bought the fms. those did not go well, both times i got harnesses from different years that werent compatible. so im just trying to avoid the headaches and replace what is sitting there now.
