I would look to the left of the fuse panel and find that 11 pin connector, separate it and plug the relay back in with a good fuse if it holds it's a problem from that point to the rear of the car, if it blows it's most likely still under the hood. So if you can separate the wire that feeds back to the trunk at one of the connectors it will separate the task at hand in half. It's easy enough to check the wiring there. It's this tan wire that can cause problems occasionally but it usually breaks not shorts. It next goes into a connector C320 which is in the trunk area, L/H corner 6 cavity connector, right near the rear tail lamp under some cardboard and the foam trunk liner. stripe wire at pin K of the C209 connector to the left of the fuse panel an 11 pin connector that runs wires to the trunk area and it becomes the tan wire headed to the back out of that junction.

I wouldn't start at this splice but you may end up there.įrom there the stock feed goes out the C100 connector which is the huge main harness connector into the car, it's under the wiper motor and is kinda hard to get at but finding it and unplugging it would separate the wiring in half, just like you did with the fuel injector harness to rule that out as a problem.įrom that connector it heads to the back of the car towards the fuel pump, and of course to your hot wire relay where it acts as the trigger, it's the tan/wht. The splice S115 is located behind the L/H valve cover inside the harness it probably isn't your problem but it has in rare instances been poked by a grounded bolt or become exposed. Oil pressure switch wiring gray wire, fuel pump prime wiring over behind the A/C and alternator area also a gray wire with a single cavity connector on the end of it, a splice S115 for those two wires just mentioned and the long run to the back of the car. Your short can be anywhere the relay output feeds the stock wiring, which is up front including the following areas: If the relay is up front like I made one of my kits you have less wiring to trace, the short would have to be up front it's not in your case now we know where it is. The stock fuel pump wire feeds the hotwire kit, it's the trigger for it.
