liamoc Posted April 22, 2011 Report Share Posted April 22, 2011 Its a holiday Friday and thought it would be a good day to do the RS HID install. Everything is mounted, and now the wiring begins. Does anyone have a clear way to identify what side is positive/negative on the '07 OM Edge headlight harness? I'm at the point of plugging in the adapter connection from the 'Edge Specific Harness' to the OM Ford Harness. The original halogen H11 bulb is keyed and only plugs in one way. The RS adapter will go either way into the OM harness. I don't want to take the chance of getting this backwards and frying something. I don't have a meter handy... Is there an easier way? I don't see an identifible markings like some have mentioned on the MKX having an 'A' and 'B'. Quote Link to comment Share on other sites More sharing options...
