I can't get the headlights to work on this vehicle, I've replaced the swith, but no luck, Help!

 

Moved to proper forum.

 

If it's wired the same as my 87 You need 12 volts on the red/yellow wire from the dash switch to the dimmer switch.

Which switch did you replace.

Have you got a wiring diagram?

 

I replaced the pull switch on the dash, and I purchased a headlight/power door locks relay, but I can't find the old one to install it.

 

Are you sure this has a headlight relay?

Take a look a Autozone.com for an online wiring diagram.

If theres no relay, you need to pull the plastic shroud off of the steering column & check voltage at the multifunction/dimmer switch.
