Today we will show you part number ETBC7 brake controller installation kit. What this kit does is it fills in the blanks between your 4 pole connector and the brake controller. Basically on the instructions of your brake controller, it will show you a link between the foot brake and stop light switch, a battery, and then a line going out to the connector out back. This kit here fills in those missing pieces. We will cover each individual part. First we will start from the rear of the vehicle and work our way forward. This part here is 7 and 4 pole to 4 pole adapter. This will plug into your existing 4 pole that you have on your vehicle. It just plugs in like normal while this white wire gets grounded to the body of the vehicle. You will have a couple extra wires. The black wire will be ran to the battery. This blue wire here gets run to the blue wire on the brake controller.
Finally, we have this purple wire which gets run to the reverse lights. If you do not need this wire or the black wire you still have to connect the blue wire for brakes. On the 7 and 4 pole adapter it comes with this bracket right here that mounts to the bottom of your bumper or wherever you are going to mount it underneath your vehicle. It comes with 2 sets of screws. These small screws will attach it to the bumper or support bracket, whatever you use. Then these screws here will hold the connector in place to the bracket. This gray cable here has 2 conductors in it, one is going to be white and one is going to be black. What happens is, this wire is going to get split back and gets connected to the 2 wires on the 4 pole to 7 and 4 pole adapter. What happens basically is you are going to take your blue and black wire and run the black wire to the other black wire. However, you will take the white wire and run it to the blue wire.
This loom will cover up the wiring from the back end to the beginning of the wire up front. Next step is to run this cable back up to your battery. This will provide power for the black wire for a 12 volt power supply going out back. The reason you want to go to the battery first is because you are always going to have some left over. Approximately 5 to 6 foot and you would have excess wire that you will cut off and run it between your brake controller and battery. So you will have 1 black wire running to your battery and the other black wire will be ran to the brake controller. So you will have 2 connections coming off of your battery. After you have already ran to the battery for your hot lead you are coming back. The wire running to the battery and brake controller will need a circuit breaker. Depending on your brake controller it is going to be a 20 amp or 30 amp. Thats why supply 3 because different brake controllers use different amps. This 40 amp you will also want to install between the battery and 12 volt power supply going out back. So it is a pretty good idea to install these side by side. There will always be one left over. To make all these connections to the circuit breaker and wiring to the battery. The kit comes with all the ring terminals to make the connections. These 2 biggest ones will be going towards your battery. The 4 smaller ones will be making the connections to your circuit breakers. We also have butt connectors to make the connections between 2 wires from the brake controller and harness. Finally it comes with 10 zip ties to help secure any excess wires to the frame components and any other stationary objects.
