ls1 in mustang help with fuel pump wiring
ok im gettin really close to starting this thing up and i have to wire the fuel pump now
its the stock 91 mustang tank with a 255lph in tank pump
there is 1 fuel pump relay under the seat and im not sure right off but i think there is another one somewhere
for the people that have used the stock camaro ls1 harness how are you wiring yours up?
i was thinking about taking the switched hot wire coming out of the ls1 computer and running it straight to the relay under the seat
would that bypass the other relay if there is one?
i believe it would be pin 85 if i did this
any help appreiciated and pics are a huge bonus
thanks in advance

Not sure about the two relay thing in a fox body, (I know there is an inertia switch in the trunk). But you can just run the Fuel Pump wire from C2 - Pin 9 (Red Connector on a 99-02 PCM) to 85 or 86 of the Fuel Pump Relay. The other side of the relay will go to ground. 87 and 30 will be line and load for the fuel pump.
