Well, now I've done it. I read about using a resetting fuse and a compass to track down where my short is. Only problem was the resetting fuse was resetting too quickly and melted the insulation.

The plus side is that I found where my short was. It was like I suspected. The +12v for the efan which was plugged into the test connector by the battery. That wire got pinched under the battery tray and rubbed till it had exposed wire. The melted wiring stopped exactly at that point moving towards the relay for the efan.

Though it did not stop traveling down the harness side. It followed the wiring diagram perfectly, getting all melty along the way. It went from the 6pin (B1-08) through to the main relay (B1-02) and on to the EGI fuse harness.

I started cutting into the harness to trace it back. It looks like the damage is isolated to just main relay harness, check connector wiring and harness and EGI fuse wiring and harness. I'll do more digging tomorrow morning. My biggest concern is that from B1-08 harness following the B/W wire back it then split. I haven't traced it back physically but I have looked at the diagrams. It's going to both the Main Relay (B1-02) as well as to (X-11) on the passenger side kick panel.

At least from the digging I've done so far and looking at the diagrams..it's looking like I"m better off running new wiring than trying to replace the entire harness. It looks like that harness covers a lot of ground. Going from firewall on driver side (I'm assuming ending at the driver kickpanel?), across the front of the bumper and ending by the passenger side headlight.

Lesson learned, now to fix my mistake...
