My reverse lights are out. Checking wiring to the switch on top of the transmission I can see the wires going to it look like shredded wheat. There is one little strand of wire holding on.

I will need to access the reverse lights switch to check continuity, make new connections and rebuild the wires to inside the cabin.

I just finished hard wiring one of the rear light assemblies but that has been the extent of my wiring repairs. The rear tail light assemblies look to use 18 gauge stranded wire.

Looking around a couple of forums I am not seeing specifications for wiring and connectors ... for any part of the wiring harness.

I took the reverse light connector apart in the cabin and the wire appears to be 18 gauge.

I do have good access to 18 AWG solid sprinkler wire.

Can someone confirm wiring spec?
Can someone tell me how the reverse light switch is connected to the wire?
What are the male spade connectors used in the plastic housing? They have small split that hold the spade in the connector. Is there a special name?

Any suggestions or warnings on lowering the transmission would be greatly appreciated.
