I'm at my wits end with wiring my tail lights. I've looked at the diagrams in the tech section, but the colors are all different, and I'm starting to pull my hair out after about 5 hours. Here's what I have: Drivers side colors Green Green Black White Blue Passenger side colors Green Green Yellow White Blue Pardon my ignorance, but in a negative ground system like this, should I have grounds? I tested continuity with a multi-meter and all of the greens have continuity to the chassis with the ignition on, and off. I can get the flashers to work, I can get the parking lights to work, I can get the brake lights to work, but not the reverse lights. The caveat - I can't get them to work together (only the flashers, but not parking or brake, only brake, not flashers or parking, only parking, not flashers or brake, etc.). Is there a way with my multi-meter to isolate each set of lights, individually, so I can get them to function together. Searched to no avail, I'm confident everything works, I just can't find the correct order. Any help definately appreciated.
