Im refitting some phillips D2R globes to another set of headlights I have, the factory ballast to bulb wiring has been cut.
There are the 2 larger gauge wires that I know are + / - for the bulb, there are 2 other smaller wires in the harness that I believe are some sort of safety wires to stop the ballast from firing up without a bulb being attached, can anyone tell me if these should be grounded or do they need some kind of resistance or signal fed to them?
I have some new D2 harness' and plugs to wire in but they are only the 2 wire kind not the OEM 4 wire.
Can anyone help with what to do with the smaller gauge wire?
