I bought a 91 dually which the fender well marker lights were not hooked up.
I am wanting to hook them up.
The tailight wires have been modified (there are no plugs) They are wires which are just sodered together.

There is a plug with four wires hanging from the frame near the drivers side fenderwell.This is the pic with the shock.

There is a plug with two wires hanging from each fenderwell.

Is the 4 wire light for the Fenderwell marker lights?

Where can I get plugs for these ? Dealers are not much help unless you have the part #.

the ones with 2 wires is for the dually fenders. Mine were not hooked up either. There are wiring diagrams in the sticky.

That 4 wire plug looks like the one for all the taillight functions.

The fender markers just need to be wired up to a parking light wire. If the wiring is all hacked up anyway, just find a wire back there that's only hot when the parking lights are on and wire 'em up.

A truck or trailer parts shop will have pigtails that plug into the markers.
