Have had on and off working windows ever since I bought my e30 a few years ago. It's an 87 and the passenger side pigtail was destroyed and the wires were too. So I thought hey why not just order a used pig tail in good shape and splice the wires together. It might not seem like that big a deal but I'm having trouble figuring out which wires go to which. The pigtail I ordered is a different color and so are the wire colors. Other than that it's identical. Does anyone know which wire would match up with the other. I think it's just because the pigtail is from a different year or something simple like that. And the pins on my driver side plug don't make good contact with the switch contacts. It's not a massive deal but it's starting to warm up where I live and with black interior having windows would be nice as my ac hasn't worked the whole time I've had the car and I plan on removing it entirely. Any help would be appreciated
