I have got a 1977 REPU that we just installed a clutch in and it runs great the problem appears to be that the headlights and tail lights are not working. The emergency flashers, brake lights, and turn signals work but not the other lights. I found the fuse panel under the hood but none of these are labeled for head lights. I am hoping somebody here can point me in the right direction on what I need to look for. I am thinking of putting the truck up for sale but would like to have everything working right.

For brake light, there is a brake light switch on the brake pedal. IIRC There are 2 green wires make sure one has a constant 12v and wires are not unplugges. Otherwise, check the fuses. I have to double check on the headlight issue

 

step 1 - go buy a test light
step 2 - download FSM (foxed.ca)
step 3 - find wire diagram in FSM from step 2
step 4- use test light from step 1 to check for power at all the power leads found in step 3.

there should be some fusible links behind the seat on the passenger side of the cab... thats the first thing i would test

i got you the FSM wiring diagrams... all you need to do is step 1 and step 4

 

Thanks, the diagram should do it.

 

There is a link to Fox.ca in your mazdarepu post.

 

Mazda really changed up the wiring on the 1977, and not for the better. The main harness isn't very modular at all. For 1977 they got rid of the fusible links behind the seat on the passenger side. There are only two fusible links on the truck, both are under the hood on the driver's side fender in a bakelite type plastic box, similar to what I've seen on the early 1st gens.
