So for all the wiring people out there, i have a question for you. There is a wire shoved in the wiper fuse in the fuse panel and then spliced using a scotch lock into the EFI MAIN RELAY(COIL) wire right before the ecu. My question is what is this doing? What sort of problem is being covered up by this? Im not sure if this is the cause of some of the issues im having like high idle once in awhile,wanting to stall,and the CEL sometimes wont come on with the key in the on position, but it still needs to be addressed. Any thoughts will be greatly appreciated! Thank you!

Never thought of that,could be a possiblity. Oh, the fuse is still in, just with the wire like jammed under/on the side of it. I Figured that was giving direct power to that EFI wire covering up something. I will unplug it from the fuse panel and see if the wipers stop working, or if it runs different. Thanks!

Alright, with the wire unhooked from the fuse,wipers work fine. But the CEL doesnt comeon unless i turn stuff on like the headlights. It will not start when the CEL is not illuminated. Is this wire bypassing the main relay? Any input is greatly appreciated! Thanks!

Crazy how they figure out how to jump it but they cant figure out the problem.

Is the wiring hacked up?

How are the grounds on the intake mani?

Yea,crazy. The wiring is not hacked up what so ever. I did actually reground those wires on the intake manifold about 2 hours ago, and its been fine with that wire unhooked now. Im not positive it fixed it though because the grounds looked fine. I'm going to test the relay per TSRM with and without that wire. Thanks!
