After finally procrastinating enough I got the tach working in my car... and it was the blue wire for the signal It was about 5degrees celcius today so i decided to get it all done.. wiring is a bit messy but it works. Now i get to put my hyper blue led's in the car tomorrow.. I found the connector for the illumination ring around the cigarette lighter and im going to use that to power my led's, so that they're on when the running lights are on.. Ill try to post some pics if i get a chance.. Thanks to all the guys that helped me out trying to figure out the wiring before
