1982 e21 323i - hot wire for high beam under dash

Hi all - have done a fair bit of work on car and my e36 318is is now sold.

Have just installed a H4 conversion kit, which included two H3 100 watt highs, which I have connected through a relay and switch.

To trigger the relay, I need a postive feed from the dip switch, so tapped into the white wire on number 50 plug connector.

All should work, but the white wire carries power when dip switch is undipped, loses power when highs are selected.

So a bit stumped. Could connect up to the high wire up at the H4 lights to trip the relay, but wanted to keep things simple under the dash.

Any thoughts would be welcome

Chris
