ignition switch fuse link (now relocated) keeps popping fuse as soon as switch is moved to the first position. While looking for a dead short I noticed that if I unplug and plug back the gray harness above the van starts back fuse stops popping. The last time it happened the black harness was the one I had to unplug and plug back. I am getting the fuse to blow by taking off from a dead start with a fast acceleration. Any clue what could be causing such a weird scenario? 1. What is popping a 30 amp breaker acting like a dead short that seems to disappear when u unplug one of those 2 harnesses. It’s no Coincidence this has happened 5 times now and will continue to blow a fuse until I unplug and replug.
thanks for any help

 

Check here, see if they have wiring diagrams for ya. See what all goes thru that plug, and see which one is shorted to ground.

 

Disconnect the battery and put your ohm meter on each lead and the other meter lead to ground and wiggle the harness until you get continuity through your meter.
