Finally got another starion. The PO changed it over to a 3" gm and translator making it run like crap. Looking for the pinout on the mas/maf plug as 2 of the wires are the same color and I don't want to hook it up wrong. Just trying to put her back to stick and go from there

It's the same as the 88 FSM over at starquestgarage, http://www.starquest..._electrical.pdf, page 8-49.  There are two duplicate wire colors in that connection, green/red stripe and black/white stripe, plus a white/black stripe just to confuse you more.  You'll need to ohm out each wire.

Thanks for the input guys, got it all swapped back to stock MAS. Removed the terrible bov, redid some vacuum lines, changed plug wires and plugs, Ran better but not great... had the bright idea to swap injector clips around and now runs even better. Not perfect but 10x better then when I bought her. Seems like some kid with
Limited starquest knowledge owned her at one point.

Kid or not, everyone starts out with limited knowledge on these things.

I understand that one. I've had 5 and still have limited knowledge on these beauty's. I got everything wired up, I'm not sure if its correct or not as two wires are the same color and the pinout I was asking for to tell me what wires are for what specific part of the sensor.
