As the pictures show I have gotten to the under side of the box, but it only has a few set of plugs. It looks like I need to get under the fuses that are protected by a cover and 8 torque bit screws that allow the plastic cap to be removed, but the fuses are in the way and have to be removed first. It also looks like I need to add a pin to the plugs under the box on both sides of it and add the wire to the fuse plug itself. I'm willing to explore it to find the way I need to add the circuit to the fuse, just was hoping someone knew already. I was hoping to have all nessesary parts to do the job. It's working as it is now, but the experimental phase is over and now I want to clean it up as if it was factory installed.
