1999 f series 863 wiring help

Great site it's my first post. I just came across this machine with around 2600 with a few issues. The auxiliary hydraulics do not work and I knew that prior to the purchase. I would like to get them going so I dug into it and this is what I found. For some reason someone got into the wiring harness and did their destructive madness and butchered it. I have a wiring diagram for the machine but can't figure it out because wires are missing. I am needing help determining where the wires going to the 10v auxiliary coils come from. The wiring diagram shows them coming from the control box but those wires are running back through the harness and back into the cab. Any suggestions, photos, or anything would be great. Thanks

Can you get some pictures so we know what you may need?
I wonder why someone butchered it in the first place.

Sorry for the late reply but was out of town for the holiday. I actually figured it out. I got fed up and pulled the loom off the entire control module wiring harness and there they were. The wires were cut and laying in the loom. Who the heck knows why but tested them and they have the 9.6 volts toggled back and forth as they are supposed to have. The coils are energizing and holding so the auxiliaries should be good to go. I am waiting on a seal kit for my bucket tilt cylinder and that is off at the moment so I can't start it to confirm its good to go. At least the wiring ordeal is over for that part. Thanks for the quick reply and I'll keep you posted. Matt

I am having a similar issue in that I can not get the auxiliary lights to come on on the aux switch. Not sure what is going on, but the switch goes back into the control module and not sure where it goes from there. Can anyone please help me with this in how to troubleshoot and where to start.

Mine would light up but would not activate the auxiliaries. Made since because like I said I found the wires cut. I would suggest taking down that panel and see if there is power on either side of the auxiliary button. If not power is gone somewhere. My machine is a 1999 863 and I have wiring diagrams I would be happy to share if they can assist.
