I'm completely challenged when it comes to reading any electrical stuff. Can someone help me to understand please what the actual function of each pin is? Here's what I think, but I'm pretty sure I'm wrong:
1= Illumination (ground)
2= ?
3= Ground
4= Illumination (positive)
5= nothing?
6= Ignition

Help?

i can test mine for you and tell you whats what?

Yeah, that would be great, thank you! If it's not too much trouble, while you're there, will you also take a picture of the wiring part that plugs into the back? I don't have a harness at all to plug in, but it would also help if I could have a visual of the plug-in to see the colors of the wires. This thread http://www.6gc.net/forums/index.php?showtopic=32806 shows it, but he also said he has an aftermarket harness? I wasn't sure what exactly the poster was referring to. Plus, in his photo, it's a little hard to tell which wires are at pins 1 & 2 vs. those on the bottom row.

Thanks!

this is what you need I think.

Griffy I have an entire parts car in my garage with everything you could possibly need and you have my number
