seems that with the help of this board im getting my mustang lined out, but it keeps showing me more problems. The fuel pump relay with the car off stays warm, i unhooked the tan/ltg wire and its not warm anymore, so i wandering what should i check so i dont have to keep unhooking it, the relay is not the factory one, and their is no relay harness, so i might have a wire in the wrong place. no 2 their is a relay that is on the same plug as the maf can anyone thell me what it goes too, here are some pics
thanks brandon

Issue 1: Check the FP relay coil to see if it's staying excited with the key off.

Issue 2: The WOT relay sits kinda under the MAF (in front of the strut tower).

i went out side and looked at it power was going to 86 or something, so i put the red wire (12 V ) i assume to pin 30, orange wire to 86, pink to 87 and green to 85 hopefully it dosent get hot with the key off gonna give it 30 min and go grab a hold of it to see

You might find that you have the red and orange wires crossed. On a SPDT relay (like yours), 30 is the battery feed for the pump. This should be orange/lt blue.
Red/blk should go to 86 (positive relay-coil power).

If you try to power the fuel pump with the Red/blk wire, you will probably overload the circuit.

you are exactly right, i changed orange to the 30 pin and it is staying cool
thanks hissin50
