:confused0024:Just got my '55 p/u on the road, including new wiring to the parking and tail lights. I was having a problem with the front parking lights and tail lights sucking a tiny amount of juice even when the old light switch was in the off position. I had a brand new Danchuk light switch for my '56 that is exactly the same that I hadn't put in yet, so I swapped out the "bad" switch for the new one. Repeat: It is exactly the same switch. So now the front parking lights are working correctly; hooray. But get this... the tail lights are now controlled by the dimmer knob on the light switch! When the switch is all the way in, the tail lights will go from off to bright by turning the knob. Both Danchuk and Eckler web sites show seperate wire pins feeding power to the parking and tail lights the same as the shop manual, so my wiring should not be the problem. Repeat: they identify the exact pin to use to control the tail lights. But when I pull the switch out to either the first or second position, the tail lights go to full power as they should. I removed the shaft and reinstalled it three times just to be sure, then I reversed the location of wires: tail lights into the parking light tab, and p-light wire into the t-light tab. Now the p-lights are dimmable when the switch is in the in (off) position and the t-lights work fine. Do I have a bad switch or a bad brain? When I get this problem solved (with your help) I have another minor question regarding the dome light; but that will come later. Cheers.
