I need to know .. it's a 2003 Grand Caravan with OE 9007 bulbs .. I'm taking those out and redoing the wiring for a custom HID retrofit setup using D2S bulbs. Need to know, factory bulb power is Ground-switched or Positive-switched. ..??

 

When you brought the kit, doesn't come with instructions?

 

This is not a kit. This is an OEM HID Xenon setup from a 2005 Acura , includes d2S HID projectors, d2S HID bulbs, ignitors, ballasts, all OEM from Acura. This is not a kit, THIS IS BETTER. Becuase it's from a different car that was actually wired for a Xenon setup, this is why I am asking this question. I am making custom wiring to plug into the G.Caravan which will include 16-Gauge ( + ) and ( - ) wiring, own Relay, fuse, and battery terminals. This will plug directly into the battery, I am not using the stock wiring for power.

Any help would be appreciated .... ground-switched or positive-switched ?

(( I suppose I can find out on my own, by multimeter tests, if I had the g.van here, but it's in another state at the moment )) ..

 

It should be switching the positive. One lead for your existing lights should go to chassis ground. The other two are high and low beam switched lines.

 

Can anyone else confirm ? ..As both options are common on dual-filament bulb setups.
