Light Wiring for Meyer Plow - DODGE RAM FORUM - Ram Forum

I don't know how your vehicle is wired but the typical lighting circuit is similar to that used by many vehicles.

The wire you seek is the output to the headlight circuit from the main light switch - if it is a separate switch. It wouldn't be practical if combined with the dipswitch. A testlamp would easily identify the correct wire.

Installing an additional switch in that wire (a 3 terminal change over switch) would send the feed either to the plough lights relay or the headlamps, though it is possible the rear fog light(s) wouldn't be able to be used with the plough lights.

I suggest you don't try the same modification when you buy a later model computerised truck.

Sounds like it's worn out, best take into the shop for repair, should only cost $20 with parts.

Check your grounds on the plow wiring,disconnect and reconnect the battery if the tipm reads too high a draw it will shut them down to protect the circut.Battery disconnect resets the tipm.

YOU WILL HAVE TO GO TO FISHER. TRY TO GOOGLE FISHER AND SEE WHAT HAPPENS. THANKS MOTOR62500...

There is a ground that is deteriorated in the harness. trace the ground lead back from the connection to your truck. Once you find the break, that should take care of your problem.

It is also possible to be a power lead, so check them also, but more often than not it is a ground.l

Hope this helps.

Here's a link to a pdf file containing the headlight wiring diagram for your year model Dodge Ram 1500..
I can't help but notice that you say you've replaced the headlight relay? That's quite odd, because there is NO headlight relay on this vehicle- only a 40 amp fuse located in the power distribution box that sits behind the battery inside the engine bay.
The switch is notorious for burning out because there is NO RELAY on this vehicle, and there is a recall (#819) but this only affects 3500 models even though the headlight wiring is the same for 1500,2500 and 3500 model Rams.
Here are two more links that will help you troubleshoot your headlights problems.
