Hi There -
Per the chart below, is pin #13 on the engine comaprtment 14 pin plug a true keyed power source? Being that the chart does not list the fuse it goes to (like it does on pin #8) I am a bit confused. I need to create a harness for my fuel pump and need a keyed power source for the relay. The PO of my car installed a faucet pump and ran it off of the positive side of the coil. I need to check again, but I am pretty confident that the original wires were removed, and for now, I want the new pump (carter 4070) to reside in the stock (rear) location. Thanks Very Much - (IMG:style_emoticons/default/beerchug.gif) Scott S Attached image(s)

Yes, pin #13 is for the fuel pump. It's fuse is on the relay board, the rear fuse (25 Amp), although a lower amp fuse is more than adequate, say a 16 amp. It,PIn 13, is only hot when the fuel pump relay is energized.

It,PIn 13, is only hot when the fuel pump relay is energized. Tom Always use a relay to cut-off the fuel pump when the engine is not running. This is very cheap insurance! Use simple diagram attached bellow. Switched power is the black (8) in engine compartment or red-white under the dash. I also attached the original relay board wiring with the wire colors. Balck-red (13) is the fuel-pump supply that YOU need to connect to switched power.   |
