Taillights and dash lights are out and taillight relay doesn’t click with switch on. Headlights and blinkers work fine.
With taillight relay removed, truck side socket has 12v at pin 2. When I jump pin 2 to 3 lights come on.
Tested relay and it’s good but replaced anyways with no change.
With relay installed, I jumped pin 1 to ground and it clicks and lights come on. Does pin 1ground relay through light switch? If switch ground is bad I thought headlights wouldn’t work?
