Ok, I have looked at many post and using the 67-72 --Napa and rockauto show same part # ---- I used these hookups to get the headlights, taillights-parking lights, interior dome light, dash with adjustments to work with key off.
Tell me where I went wrong but I tested using a meter then hooked them up and tested on the 46 truck.
Post number:
1 --- 12 volt battery
2 --- dash lights
3/4 ---taillights, front parking lights
5 --- 12V battery and dome hot wire (orange)
6 --- headlight to dim/bright switch
7 --- not used
Dome ground on dome ground lug --front right -top
Grounded switch frame.
If I used 12 battery only to #1, switch only yielded voltage on post 6 and 7.
