Anybody use a Painless Wiring harness?

I am having problems, when I turn my lights on, headlights come on and that's it. no tail lights or running lights. Any ideas, thanks

When I pull the head light switch half way the park lights come on, all the way out, park lights go out and head lights come on, nothing in the back, no horn??????? My truck is a 71

Probably need to check the grounds. Or maybe the switch. I am currently wiring up my sons truck but haven't finished it. Hope this helps. Someone with more wisdom than me will chime in soon.
Good luck

It sounds like the switch. There is a great mod using Bosch relays that reduces the load on your switch so they last much longer. It keeps all that amperage out of your dash and your lights will be brighter.

By all means you're tail lights should be working when the headlights are on, but I seem to recall reading on here that the parking lights are supposed to go out when the headlights are on from factory. I tried a quick search for the thread but have not found it yet.
