brake controller
i have the square 4 prong outlet under the ashtray for the brake controller but there is no wire out back for it and there is no fuse in the fuse box (under the hood) and one can't be put into it but i checked the voltage on the plug under the ashtray and there was voltage.
So does that mean I can take the blue wire and run it all the way back to the plug and call it good?
does there need to be a fuse inline with the blue wire between the plug and the trailer plug out back?
I got the wires just taped up out back for an accessory and trailer brake. and dad is talking about buying a bigger camper so it would be nice to have those 2 things.

Here a wiring diagram for the wiring for your plug under the ash tray, C210:

You will need to splice this into the controller thy sell you.
Then you need to cut the blue wire some place between the firewall plug and the ashtray plug and run it to plug on the rear of the truck.

ok was going to start wiring it in and was checking for voltage and hooked the test light to the white ground wire and checked each prong and this is what i came up with.
white ground
light green voltage when brake pedal pushed
red no voltage
blue no voltage
What i have gathered is the red is my constant 12v and there is no voltage there at all so do i need to cut that wire and find a constant 12v source and wire to that. The red and blue wires go to the firewall plug. then run the blue wire to the trailer plug
white ground
light green voltage when brake pedal pushed
red no voltage
blue no voltage

The rest of the wires you tested seem to test as they should.

yes that is right but there is not any connectors in the box were a fuse can slide into. The spot is there just not any connectors. I guess i didnt look for the red wire coming to the fuse box. how do i go about getting power to the red wire
If you need me too I can probably take a couple close up pics wednesday or thursday.

If you need me too I can probably take a couple close up pics wednesday or thursday.[/QUOTEIf the red wire stops at the firewall then you have two ways to go about it. You can cut the red and blue wire at the firewall connector and splice a wire on to each of them. Run the red wire to the large stud of the starter relay on the fender battery side. Make sure you put a 30 Amp inline fuse in this wire near the starter relay. Run the blue wire not fused to the plug on the rear of the truck.
Do you need a diagram of the plug on the rear?
I love photos of under hood or under dash items and wiring, if you take them just email them to me with year, engine size and model to this email address.
Here is a photo of my Firewall plug C205 with Blue wire on pin #2.
