Today, i installed a new headlight switch with the old harness. No difference, still hap hazaard/haywire lights.

I then took a new harness and powered it up at the alternator- yes its an alternator and laid out the wires as they would be installed. A test first before install.

The front lights worked as they should. so it was probably the harness.

When i install the harness for good, i will try the old switch with the new harness to see if it works.

I prefer to use the old switch. for a few reasons. The first is that the new switch is one inch shorter than the old switch which is creating a problem with the clamp/spring/latch that holds it in place.

Thanks for the help
