Today, on our 2004 Jeep Wrangler, well be installing the Tekonsha Prodigy P2 Brake Controller, part number 90885 in conjunction with the Etrailer Brake Controller install kit, part number ETBC7. Using the hardware and bracket provided, we can secure the 7-pole bracket to the new 7-pole connector. The 7-pole connector will have both a four flat and seven blade trailer connection points. Well that bolts and nuts provided to secure the 7-pole bracket to our new 7-pole. Now, as we have our fasteners installed finger tight, well go ahead and run them down to secure the bracket.Next, we can go ahead and take the bracket and secure it directly to the hitch-mounted bracket. Now that our 7-pole is secured to the hitch, we can start connecting our wires.

Before I connect any of my wires, I'm going to go ahead and tape up a portion of our 7-pole pigtail here just to help bundle the wires up and protect them. Using some black electrical tape, Ill go ahead and put it around the pigtail. Note, this is also inaudible 00:01:48 you can use the wire loom thats provided with the install kit. Next, well take the 4-pole plug thats already been installed under the vehicle. Bring it down to our 7-pole where we can connect the two flat-pole connectors together.

Ill go ahead and remove the cap because itll not longer be needed.Then before I make that connection, were going to use some dielectric grease between the two connection points to help prevent corrosion over time. Well be using the Edelmann Dielectric Grease, part number 11755 and then make my connection. We can take the purple wire used for trailer reverse lights. It will not be hooked up in this application so were going to go and cut it short, but its long enough that if we need to, we can go back and add to it to connect the trailer reverse lights. Next, were going to attach the gray duplex cable to our black and blue wire leads.

The gray duplex cable has two wires inside. Were going to go and expose them by cutting back a couple of inches of the sheathing. Be careful not to cut the wiring underneath when you split the sheathing. You can peel it back, just cut it off out of the way. Then well go ahead and strip back the two wires.The black wire will connect color-to-color, black-to-black and this will provide the 12-volt hot lead directly to our 7-pole connector.

The other lead will be the blue wire from the pigtail and the white wire from our duplex cable and this will provide power to our trailer braking. Now, once Ive made my connection points back here, I'm going to go ahead and finish wrapping up my electrical lead with some black electrical tape. This will help keep our connections clean from dirt, dust, debris and moisture. Ill get my wire out of the way before I tape it up. Im just going to simply route it up and over the frame, going towards the front of the vehicle and ultimately, up to the engine compartment. I will include the white wire with the pre-attached ring terminal which is going to act as the new ground for our simple connector.Now with our wiring taped up, I'm going to go ahead and take the white wire with the pre-attached ring terminal and secure it directly to the frame. This should provide the ground for our new trailer connector. We can use a self-tapping screw thats provided with install kit to secure the ring terminal. Now, with our self-tappers in place that secured our ground wire, we can go ahead and secure our wiring and start running our gray duplex cable up to the front of the vehicle. Keep in mind, when routing any of your wirings, stay away from any moving components such as inaudible 00:05:15 suspension and excessive heat such the exhaust. As we route the wire, well use the black zip ties provided with the install kit to secure it.Once we finish our routing and securing the wire, well cut off the excess from the zip ties to clean up our install look. Now with our wiring routed here to our engine compartment, were going to use the manufacturers grommet just below the manufacturers wiring harness to route through the grommet and into the cabin of the vehicle. To get through the grommet, were going to use our utility knife and just cut a slice in it. Now weve got a slice big enough to route three wires to it. The white wire from our gray duplex cable we ran from the back of the vehicle thatll ultimately run to the brake control and pigtail then the power and ground for the brake controller.To do that, Ill go ahead and mark our length where its going to route into the grommet. Well use our utility knife to slice the sheathing so that we can split the two wires out se
