EEC relay wire
On my 87 mustang gt the wire from the starter relay to the eec relay got corroded at the fuse link so i had to cut the fuse link off. Now when i try to put the 30 amp fuse or a 18 ga fuse link it gets blown can't get a 20 ga fuse link at the store. Any ideas on what to do? Its the blck/or wire coming from the eec relay on the wiring diagram. http://www.allfordmustangs.com/forum...aldiagram2.jpg

RE: EEC relay wire
Fixed that problem, the wire now gets power, butthe fuel pump still won't prime when i turn the key on. When i ground the fuel pump test port i can get it to prime and can turn the engine on. Any ideas what it could be?

RE: EEC relay wire
Back to the old problem, now when i hook the wire from the eec relay to the battery it gets power, but when i turn the key the fuse blows. So there is a short somewhere, where should i begin looking?

when are you people going to learn to make your own relay circuits

RE: EEC relay wire
find the relay signal wire at the ECM, cut the wire.
connect (solder preferably) and tape (shrink tubing preferably) a new wire lead to it.
run the new wire to a suitable location... stock location is fine.
run a fused 12v source wire to that same location.
Install a BOSCH 5 pin relay with +12v as circuit close trigger. I like these!
make a ground to chasis.
run a signal wire back into your trunk to the old +12v feed wire.
Cut the old wire, connect (solder preferably) and tape (shrink tubing preferably) the new feed wire to the pump.
Now you will have 4 wires at the relay, and hopefully a relay harmess... If not, use female spade connectors (insulated preferably), and connect the wires to your relay.

I dont see how much more plainly I could put that.... its not exactly difficult... I gave you step by step directions.
