John Deere 790, Farmall Super C
I have been having some troubles with the flashers on the back of the tractor and started chasing all the connections.
While doing this exercise, I noticed that there are a lot of branches off the wiring harness that don't have anything plugged into it.
I'm assuming that this is for accesory type lighting, but not sure.

Does anyone know if there are light bars, additional headlights, etc. that I can buy to plug into the harness.

It would be nice to have some extra light during the winter when i'm cleaning up snow in the dark.
All I have is the 2 headlights in the front, and the bucket blocks a lot of light.

On my 4210 the purple leads are for rear work lights. Six or seven others are for a trailer electrical connector.

One of those connectors are used for the rear work light. If you don't have a rear work light, it mounts in that hole in the fender (either side) just aft of the roll bar.
As far as the other connectors, best you have the wiring schematic for your 790 (there were at least 3 revisions before the 790 became the 3005).
Lots of folks have added lights to the 790...do a search focusing on the Deere Owning/Operating forum and you find a lot of reading about how to install and mount those lamps.

The pigtail for rear aux lights was easy to find on my 3005... verified with my volt meter, a light, some wire, a few male 1/4" blade stakons and 20 min later it was done. All the lights come on together but I plan to put a switch on the light itself to allow front only.
