I just installed the putco harness in my 89 Comanche. Low beams work great, but when I click on the high beams I get no headlamps at all. All other running lights work. Any ideas?
On the drivers side, I plugged lamp into new harness and left the old plug dangling. On the passenger side, I connected the old plug to the male plug on the new harness and the headlamp to the new female plug. Plugged in new relays and connected red wires to the battery.
I haven't read of anyone else with this problem.
