I just brought some new projection headlights on ebay for my 05 Civic Si and the plugs are not the same as the stock headlights. We cutted the plugs and connected the wires manually. There are 2 wires for low beam and 2 wires for high beam, but there are only 3 wires on the projection headlights. So I figured out to connected the power cable from the low beam and the high beam to the 2 power cables on the projection headlights. The other wire from the low beam and high beam are the ground cables. But with the new projection headlights, there is only one ground wire for both high and low beam. So I figured to connect both ground cables from the car to the ground cable on the new headlights. When I turned my low beam on, both the high beam and the low beam came on even on the other headlight which is still stock. Then I tried to disconnect the high beam ground wire from the rest. When I turned on the low beam, both the low beam and the high beam came on projection headlight and on the stock one only the low beam came on.

Please help!!!!!
