I need u guys to do me a big favor if someone out there with an 87 trans am or close to it with a 305 TPI I need someone to take pics of the wiring to there MAF power relay, Fuel pump relay, and Burnoff relay

 

I ALSO NEED HELP WITH THE WIRING ON MY FUEL PUMP RELAY. THE WIRES WERE SINGED SO I GOT A NEW CONNECTOR OFF A JUNKYARD JEWEL. THERE ARE 5 WIRES TAN,BLACK,GREEN,RED,AND ORANGE . ON MY OLD CONN. THE WIRES WERE ALL WHITE FOR A COUPLE OF INCHES BEFORE THEY WERE TIED IN WITH COLORS. THE PROBLEM IS ONLY 4 WIRES WERE USED ON THE OLD ONE TAN,BLACK,GREEN AND ORANGE. PLUS THE ORANGE WAS HOOKED UP WERE THE RED GOES.NOW THAT I HAVE A NEW CONN.TO HOOK IT UP RIGHT I CANT FIND THE RED WIRE TO TIE INTO. I KNOW IT GOES TO THE FUEL PUMP PRIME CONNECTOR FROM THE WIRING DIAGRAM I HAVE BUT I CANT FIND THE RED WIRE AND I DONT KNOW WHERE OR WHAT THE FUEL PUMP PRIME CONNECTOR IS(DIAGRAM WAS NO HELP HERE) A PIC OR EXPLANATION WOULD HELP A LOT ITS DRIVIN ME CRAZY DIRTY ILL TRY 2 GET U SOME PICS OF THE OTHER 2 RELAYS SINCE MINE R STILL HOOKED UP RIGHT(THANK GOODNESS)

 

Red wire is the prime/test lead. It goes nowhere other than being a 3 inch long wire that terminates with a female connector. It was used a a test for the fuel pump. Not all cars have them,

 

OK SO DOES THAT MEAN I CAN JUST HOOK UP THE OTHER 4 AND EVERY THING WILL BE ALL RIGHT? ANOTHER QUESTION TODAY I CHASED A RED WIRE THAT PLUG IN TO THE FIREWALL ON DR SIDE IT WAS CUT SO ONLY COUPLE OF INCHS POKED INTO ENGINE COMPARTMENT. IN THE CABIN IT RAN TO THE DIAGNOSTIC PORT. I THOUGHT IT MIGHT GO TO RELAY BUT IF IT DONT WHERE COULD IT LEAD? THANKS 4 ALL THE HELP

 

Yes the four wires will work. Orange is 12V always, the black with white stripe is ground, the green with white stripe is from the computer and provides 12 volts for 2 seconds when the key is turned on to prime the fuel rail, and the gray wire goes to the fuel pump. Don't know about other red wire at the firewall.

 

zegman: thanks a lot that does the trick. so the red wire on the relay is to test the pump i guess? dirtyd: i havent forgot about the pics i just aint been 2 the shop in a few days(kids) but i will get them today if still needed k

 

yeah cause i think my maf might be on the wrong one because when i put a new one on it doesnt want to work so ir your still able to get me a pic with the wires in it that would be appretiated

 

SORRY ABOUT THE DELAY...BUSY...BUSY...BUSY. OK IM ONLY GOING 2 COVER THE BURN OFF RELAY(HAS 2 ORANGE WIRES) AND THE MAF RELAY(HAS THE 1 RED WIRE) SINCE ZEGMAN COVERED THE FUEL PUMP RELAY. OK ALL THE ORANGES R 12V POWER AND THEY ALL MEET ABOUT 8INS FROM RELAYS.THE 2 BLUES JOIN AND GO 2 MAF SENSOR. THE RED ALSO GOES 2 THE MAF SENSOR.THE TAN JOINS THE TAN FROM PUMP RELAY AND GOES 2 PUMP N ECM.BLACK N WHITE GOES 2 GROUND. SOLID BLACK GOES 2 ECM. HOPE THIS HELPS LET ME KNOW IF NEED MORE
