I have a 93 Ranger 3.0L that I have been rebuilding - almost done. Until I noticed that when I turn on a turn signal (either side gives same results), I noticed my tail lights blinking too. Also, the High Brake light on the cab blinks too. A couple of notes: I've replaced all the lights with LED Lamps. I've replaced the Blinker with an LED blinker (that was fun - I had to run jumper wires out of the fuse block to the flasher in order to get the right polarity on the flasher). The truck also has a new adapter for a 4-wire trailer connector.
I've tried replacing the rear turn lights with the normal style lights and get the same results. I've tried removing the adapter for the trailer wiring and get the same results. I've read a couple articles that indicated it might be a grounding issue, so I added extra ground wires (one on the turn signal connector and one on the brake light connector) at the left rear turn signal and still get the same results. The new ground wires run to a new screw I added into a brace just behind the turn light assembly, making sure to sand down to bare metal before making the connection. I've also measured the resistance of the grounds and I'm seeing 0 ohms to the body. Looking at the basic wiring diagrams in a Hayes manual, I'm not seeing a common path for the power to get from the rear turn signals to the high brake light nor the regular brake lights (but they don't show the internal working of the switches, so could be hidden in there somewhere).
Any additional thoughts on where to look or what to try? I'd like to start driving it, but really don't want to be venturing out into traffic with funny tail lights.
