Hey guys, Im hoping to get a little help fixing my HID on my drivers side. All of the sudden I noticed it wasnt on and needed to make a long drive home, fuses all seemed fine. So my uncle quickly made a jumper wire and took power from the passenger HID harness and ran a single wire to the driver side harness and it worked perfect.
To me that says the bulb and ballast are perfectly fine and its a wiring/relay/fuse issue
Is there anyway I can diagnose this further? I have unhooked the temp wire as I wasnt sure how safe it was to run extra current around like that.
Appreciate the help, I can post pics or anything that would help

thank you
