The first thing were going to do is mount the wiring harness to the van. Well have to make a few connections. Well run this to the stoplight switch, the red wire, the white will get run to the battery ground, and the black will be ran to the positive ground. The blue wire will get run all the way to the back to the seven pole connector. Well do the brake pedal switch wire first, this gets connected to the cold side of the brake switch. Which means when you hit the brake, the wire comes on. Next well run our last three wires, which well have to go out the firewall. Theres a nice handy grommet here, well put a slice in it, poke our wires through and make our connections to the outside. Be sure to leave enough on the inside to be able to reach your brake controller. To mount our bracket for the brake controller we have this nice flat spot right here across this gap.
Well bridge it with the bracket here that will give us room on both sides so we can install both screws for the brake controller. Well mount our brake controller up, well plug in our harness to the back of it and then mount it. What we can do next is mount our circuit breaker, which is 30 amps. Generally anywhere on this firewall will be fine. As long as its easy to get to and drill, well make our wire connections to that and go to the positive side of the battery. Well start by taking our ground off the batteries so we can work on it safely. Well now get our ground wire ready. Well leave that alone and start working on the 12 volt wire. Well start by cutting a length of wire between the battery and the circuit breaker. Then well get our ring terminals. Well then install it to the copper side here, which always goes to the battery. Now well make our actual connection to the battery. From this auxiliary side well run our extra wire here back to here and make our junction there. Lets fix our ends. Now tighten them down. Well install a couple zip ties to keep the wires out of the way, then put our terminal back on the ground. Finally our blue wire will be ran straight back down and back to the seven pole. Well get this wire ready to go and put a connector on it. Now we route our wire straight back down and around this steering column away from it and to the bottom. Weve pulled it down and away from the steering column and zip tied it to the wire harness going all the way back. We have some pretty nice tension but not bow tight. You can still flex it around. Go ahead and run this wire all the way back now.
Well just follow the lines going down the frame rail. Well meet with this previous install and run down to the seven pole. Next we disassemble this connector and run our wire inside. Go ahead and put our ring terminal on the end of our blue wire here. Now well hook it up to the right circuit which will be labeled blue on a seven pole. Now all of our wires are ran, well test our circuits out and make sure they work. Once you check everything you should see youre connected on your brake controller, then you know everything is working fine.
Today on this 2004 Dodge Sprinter van, were going to install part number 39523, the Pod brake controller. Also to install this brake controller were going to use part number ETBC7, the installation kit. Well start off by installing our bracket and our seven pole wiring harness to the bracket. With our bracket installed well go and add the grey cable. Well split the sheath back a little bit and well have a white and black wires inside. Well connect those up to the wires from the seven pole.
