If you have no voltage to the right rear, it is in the wiring, based on the info given. There is a plug underneath the bed by your rear bumper. Pull it and check for voltage to the passenger rear light. There is another connector located below the Master Cylinder. Let us know weather the voltage is or isnt in these connections.

EDIT: I just realized this was the 67-72 forum. Dis-reguard the connector locations

Anderson, The brake & turn signal share the same bulb filament and wire. With the right signal flashing unplug the connector at the rear of the drivers side frame rail and move forward.

My guess is there is a break in the wire somewhere. Sorry, but it will be a hands on dig it out. They can be big hemorrhoids sometimes.

Thanks, I was afraid it could be broken wire somewhere. The problem is in cab area for sure.

I had a broken wire along the frame rail (driver side) tear the tranny cross member. I'm still working on the truck and have not checked it but I did have the rear left tail light out before I found and fixed the broken wire.

Check the fuse box it might be seperated coming out of the box. It could have shorted from the connector in the box aswell.

Don't think this will help you but in trying to get all the tail lights working on my '72 I ended up rebuilding the entire tail light harness from the connector on the frame near the end of the bed to the tail lights. The wires coming out of the connector towards the tails were all bare corroded and mostly broken.
