Need Help Identifying Two Wires

[Bravo2Uniform]

1986 M1028 - equipped with aftermarket snow plow and salt spreader. Those aftermarket items have been removed.

I have two mystery wires that I cannot find on the wiring diagrams. The first is a 3 Red wire with fuse link that goes from the far right of the firewall power block to nowhere (not the green headlight wire - a # 3 gauge red wire. Not shown on any schematics I've seen - probably for snow plow equipment). See picture.

The second is a LT Blue / Red with connector. I am assuming this has not been hooked up for a while it was blocked with grease and grime. It goes through the fire wall with the GP module wires but does not go to the GP module - goes to what appears to be ignition wires and terminates at a connector.

That plug is the fuel pump wiring that is used on the M1010 rear heater. Also used on the cargo bed heater that is part of the arctic kit. The green wire runs to the front right turn. I am not 100% sure but I think so. Good Luck.

Thank you. When you are troubleshooting and you start finding wires that are not on your schematic you kinda start wishing you'd bought a Hodaka Road Toad instead.
