So here is what I’m working with:

Issue 1.1: Pin 75, wire is cut and has 3’ of wire spliced into it going nowhere.
I believe there was once a wideband installed.
Fix: remove extra wire and solder/heat shrink harness wire back together
Use a positap with fresh wires when I install a wideband.
Issue 1.2: Pin 75&76, there is a large green casing with some sort of insulation that has been taped up and spliced into pin 92 for sensor ground. There is a black and white wire in the case white wires being pins 75&76. The pictures I hope show what’s going on but I don’t really understand what all the loose wire is I pulled out of the gray tape or how to go about correcting it. Any advice?

“Issue 2”: pins 13&26 - both are ground wires about 6”-8” before the plug one wire spliced into the other and is looped and taped with electricians tape. Looks factory just want to confirm?

That looks ugly. Im sorry I can’t be of much help since I purchased a new ECU harness from OHM Racing (highly recommend) but If you haven’t already make sure you check this post out.

It should help you track down where things are going.

The loose wire is ground shielding and comes from the factory like that.
Heres some images and links.

Thanks, that is what I was using to gather the details I have so far. I wanted to do the OHM harness but my wife put the brakes on that pretty quick

Thank you for the link! I should be able to have this straightened out pretty easily now.
