Oops, I cut a blue wire leading to the back

[musigenesis]

In the course of removing my ceiling, I slightly nicked the conduit containing the wires leading to the back with the zip wheel on my angle grinder; on inspecting I saw I took a bit of insulation off a few wires but completely severed a blue one. Yesterday I drove my bus to the mechanic (he'll have it for awhile so I can't just check this myself) and on the way there I realized my right turn signal was not working (or else it was working but the indicator light for it in the cab was not working) although the left signal was.

Does anybody know if that blue wire is the right turn signal wire? More generally, is there a reference manual or something online for my bus that I can look at to try and figure out what wires go where? I can see this being relevant for more important things than the turn signal.

Have you tried to hook that wire back up? Getting ready to do a harness clean up on mine and see the wires in the harness are all numbered separately to make tracing very easy. Go to the signal that isn't working and check the wire numbers or colors.

What are we missing?

“I cut wire, now light doesn’t work.”

Seems pretty likely you cut the wire to the light.

Well, like I said, this is more a question about finding some kind of resource or manual that tells me what the wires in my bus do - so that when I inevitably cut something more important I'll have something to tell me how badly I just screwed up.

There are wiring diagrams available. Some manufacturers make them easily available, some not. Usually there are two, one for the chassis, one for body. Why don't you just splice the wire? Put your bus model in your signature so we have some idea of what you have. It's easier to steer you in the right direction.
If you are going to do a conversation you should learn to do how to repair things, paying someone else to do things will eat you alive. This is a really minor 5 minute fix.

I understand the OP wanting a wiring diagram to avoid future screwups. I'm looking for diagram for my Genesis before I start cutting any wires.
