New M880 owner, what spare electrical parts should I keep in the glove box?

Pretty easy; here's some good instructions. 1970s Dodge truck steering column fix

Thanks very much for that. Once I'm in there, I need to see why the steering shaft isn't grounding and maybe run a jumper so I can have a working horn.

New ignition switch install was easy, new wires are thicker gauge. Working well.
