Questions: My 52 m38 has been converted to 12 volt but still has the 3 lever military light switch. I don't see in the pictures the harness that plugs into the back of that switch. Will this harness work for my vehicle?
Question By: Joe Fowler on Oct 16 2018 2:38 AM
Youll probably have to convert to a standard headlight control switch part number: 946613 would be the easiest. Then you can still have the 3 lever style switch to keep the military look.

Questions: Can you use the original 3 lever light switch with this harness instead of adding pull light switch?
Question By: James Izatt on Mar 7 2017 4:34 AM
I'm sure its possible but you would have to rewire your original 24 volt turn signal switch.

Questions: Does this harness use the original 3-lever military light switch?
Question By: gerry on Oct 25 2016 5:14 AM
If you are 12 volt then you would probably convert to a push/pull style switch.

Questions: Would this wiring harness, identifies what wire goes where? For simple installations? I do have a old directional signal on the column, I do not know if it works or not? Would it be smart to replace with a new one? Trying to get all the lights to work, including the headllghts, brake light and turn signals. Thanks, for your help in this matter. This is for 52 M38A1 (12 Volt system). Respectfully, Jim
