My 98 did not have a tow package, but the PO had installed a powered taillight converter, this worked fine until it apparently shorted out. I ordered a replacement unit, and replaced it. I used the originally installed plug in pigtails because they were conveniently color coded. I checked to verify the power wire and the signal wires were all correct, and proceeded to solder and heat shrink the connections. So far so good.
Then I checked the output for the correct voltages and placements. And things got weird. The turn signal wire would flash the testlight, but at the same time the running light wire would flash. I figured a bad ground, and ran an extra ground to beef up the factory one. Same issue.
I hooked up my trailer, testing the lights beforehand(they were all good and wired correctly) Nothing.
Then I probed the connection to the trailer, still nothing. Just for giggles I probed all the input feeds to the signals before the converter, all working correctly, Then I probed the power feed, and my probe showed good power, but when a signal was activated it showed a short to ground, same thing with the brake and running lights activated. I removed all the taillights form the equation, still the same issue.
I replugged the lights, and removed the converter, and by using my power-probe, simulated a turn signal voltage going in, still nothing.
Did I miss anything obvious or is it just possible I got a bad unit from the get go? It was a valley unit, ordered locally but sourced from Rigid. I called Rigid, they gave me a number for Valley, but after a few hours of a busy signal I called Rigid back and got someone else, who informed me that Valley was out of business and they no longer stocked that particular part. Weird, because they shipped one to me 2 days ago! They have suggested I return it to my supplier and order a different unit. I just don't want to condemn this one if I missed something.
I've wired a few hundred vehicles for trailers over the years(did 3 complete wiring and surge brake setups on 16ft tandem axle trailers in the past 2 weeks with nary an issue) so I'm pretty sure I nailed it, but, you never know.
Anyone chime in on this?
