Litronic dip not equal?

[AKnowles]

I installed a set of litronic lights with the computer. Both headlights move, but not equal amounts. When I turn on the lights then turn on the ignition, the drivers side lamp dips significantly (maybe 10-15 degrees) down then about 5 up before leveling off. The passenger side though barely moves a degree or two. Both lights move a bit (supposedly 1.5 degrees according to the information I found previously) when the high beam is engaged.

Any idea why the passenger side is not dipping as much as the drivers side?

I checked the connectors and both are solid. Particulalry the one on the mounting plate. There is no give in this connector and all bulbs work.

Also, the drivers side internal wiring is cracking. A lot. Should I ignore it, spray it with plasti-dip, or bite the bullet and actually rewire it?

Thanks for any insights.
