I had my D2 installed, and the shop refused to do it, no matter how much I offered them, so I figured it was no big deal, having an electrical background, I'll do it myself! The problem is, ive tried many grounds, and none of them work...
First I relocated the pin, to the spot above the ground, and figured I'd just use that ground. Tried it, and it didnt work, So then I thought, well if the parking brake is grounded out, Ill use brake sensor wire, No Go. THEN I thought, maybe I need to tap into the MAIN ground for the radio, off the wiring harness on the car. So I found the connection , right where it plugs into the wiring harness for the radio, and I turned it on....and....NOTHING!
Im not sure what Im doing wrong here, but if anyone could help me out, I'd appreciate it!
