MACH wiring help - Focaljet

**utahSVT** · 03-03-2007, 02:51 PM

Ok, a while back someone on ebay had an awesome deal on a bunch of MACH headlights for like $400. I know a few people on here picked may have picked some up. The housing did not come with the stock plug that the SVT came with, they were already just pre-wired into the housing. What I need help with is I'm trying to install these and I cut the stock plug off my car (when I sold my original MACHs), exposing I believe 6 wires (just like the diagram). The pre-wired headlight only has 5 wires. I plugged in the ground from the headlight and then turned on my car to get some + power and tried to figure out which was which. It seemed like I could only get 2 hot wires from the car to power up all the bulbs (HID, highs, blinker, city)?? Would someone be able to suggest a wiring scheme that would be able to incorporate the 5 pre-wired wires with the 6 stock wires??? I think what confused me the most is the 2 black wires. Thanks for any help!!

Any way of getting a picture of what you're dealing with?

I am getting a feeling that the eBayer just consolidated the two ground wires into one, and that's why you only have 5 wires from the light. So maybe you need to consolidate your two ground wires from the car into one wire and that goes to ground in your newly purchased lights?

The Mach HID's need two seperate grounds, one for the HID bulb and one for everything else.

I would assume they are designed that way for a reason.

I used the ground from the main harness for one and the ground from the park/turn in the grille for the other. I also spliced into the grille light wiring to make the turn lamp and city light in the HID housing to work.

Well after messing around with it some more (and blowing a couple fuses) I was able to get the drivers side working fine - all four lights run independently with just one ground but on the passengers side I couldn't get the city light to run independently. No big deal. Thanks for your helps though.
