eBay Headlight Questions

[Vanguard]

Working on the 2001 this morning. Today's (and likely tomorrow's) job is replacing the stock non-HID headlights with set of DTMOTO projectors/halos from ebay.

The basic install seems to be plug and play, but the halo wiring is just 3 sets of +/- wires coming out from the bottom of the new headlight assembly. Unfortunately there are no instructions.


I've done a bunch of searching, but can't find any resources pointing me to the best method of wiring the halos in. All the references seem to be regarding HID lights or separate add-on halos. There are a couple of threads suggesting a relay and tapping into the fuse box, but no real direction.



Any suggestions would be appreciated.

I power my halos from my precat O2 sensor. The heater wires should both be white. 50/50 guess which is +. Used ground from headlight.

If I get a chance I'll take a pic so you don't have to guess. Don't use the ground from the O2 it's how the computer controls the O2 heater.

You'll be very happy with the results other than the halos are dim compared to the 8x as expensive OEM models.

Added bonus: the O2 power stays on for a while after key off so you get to see the halos regularly as you leave the car.
