The connector pin numbers are marked on the connector, but be warned, they are very tiny numbers molded on the connector. If you install the Mopar connector, then get the Dodge harness that should be available for your brake controller, and plug it in just like it was a Ram. If auto elec doesn't know,could it be the trailer? The dark green wire with light green tracer is indeed the wire I was looking for. Obviously it is a fault with the vehicle, the brake controller or the Auto Electrician. Well attach the white wire so that it runs back to our seven pole and pull it into the cabin of the vehicle.
Also on this application we have an open frame which means well be able to route the wire inside the frame up to the engine compartment. I then started the jeep, and was relieved that no trouble codes were present. This will help keep out any dirt, dust, debris and moisture from the connections. On the Jeep the right hand brake light comes on but no lights on van. Press the button on tow pro left hand brake light comes on, got brakes, light drops out, then no brakes.
The bulb glowed brightly when the brakes were applied. The wiring between the two blue plugs was backwards positive and negative power swapped, brake sense and trailer output swapped. Now with those connections made well make a connection with the manufacturers four pole and the four pole connector coming from the seven pole connector. I had a 30 Amp extra wire in the connector by the driver's door that is for the aux light bar that most don't have. Note: You may have to rearrange the terminals in the pigtail connector that goes to your controller unit.
I hope you, or someone, can answer my follow-up question. Next well take the seven pole bracket and attach it to the Tow Ready Universal mounting bracket, part number 18140. Just pull the white tab out slightly on the side of the clip and use a small screwdriver to push the retention tab in holding the individual terminal in the clip and pull it out of the back of the connector. Please leave a review here. Can someone tell me which wire I need and where to find it? We got this picture on the net that we consider would be probably the most representative images for jeep jk trailer wiring harness diagram. Then well start by using a small pilot bit and enlarging it to the side of the grommet necessary to install it.
Now with our wire routed to the engine compartment well go ahead and pull it up where we can gain access to it at the top of the engine. This is not possible via the pedal switch. Well first take our seven pole mounting bracket and install it onto the new seven and four pole connector. If your talking about the brake wire then no as it's the blue wire and is plenty heavy enough. It's going to minimize the need for wire splicing and is a direct bolt-on for 2008 through 2018 Wranglers.
In my case this involved swapping pins 1 and 4, and swapping pins 2 and 3. We all know every ones opinion; will be different from one another. Then reinsert in the right place. Those brakes need some serious amperage from what understand. I've installed the tow plates Blue Ox , and I've set up the Roadmaster 9160 Air Brake system with Breakaway.
If it turns out playing havoc with the electronics, another method would be to tap off the top center brake light using a diode and a relay for isolation and minimal current draw on the brake light circuit to send the 12V current needed from the 12V outlet wiring in the trunk of the Jeep. Now we can strip back both wires. I haven't yet gotten back under the dash to finish the project. If so it might be there. I'm trusting Roadmaster to know what it's talking about, and I'll keep you informed as I gently work my way through this connection. I believe Roadmaster has researched the electrical issues and if there is a problem, I would look to them to resolve it. Well repeat the same process with the white wire from the duplex cable and the blue wire from our seven pole connector.
This will allow me to make another mark and trim off any excess that wont be used at this time. I'm going to start another thread, asking what types of braking systems folks have for their Toads, and how they've wired them. What do you mean by 'not working' no lights? This time, I made the connection with a blue-colored clamp-on connector for 16-18 gauge wire , and taped it up so it shouldn't come apart. Both of the wires you mentioned go to a circuit board in the Body Control Module. As was said, the technology that is involved is new, and it doesn't provide any comfort when Jeep advises against making any modifications to the electronics. First, before we make any of our wiring connections were going to go ahead and trim back the purple wire as it will not be used in this application.
Here's a link for you. I will heed the advice I've been given regarding pulling the fuses to the braking system before I tinker with the wiring. From memory, I believe the power wires are the same gauge, but brake sense and trailer output are different gauges. Can someone tell me which wire I need and where to find it? I can appreciate the value of a wired system, but you are not the first person having difficulty tapping into the brake switch on the Cherokee. Hi Susanne, its pretty basic if you have the tow pro elite installed. I'm glad that Just for Jeeps sells this part. Would you know where I might find and identify the 'hot' wire to the third stop light somewhere near the driver's area of the vehicle? The other thing that would bother me about tapping into that wiring besides the manufacturer's specific warning about tapping into the electrical system is it goes to the Body Control Module where who knows what's going on in there since it includes non-serviceable circuit boards.
Thats the reason we are presenting this topic at this moment. Pin 60 is on the top-right. Now with all our connections made well go ahead and take some black electrical tape and wrap up our wires. This isn't your Father's Oldsmobile. It was simple to connect my wiring to the plugs, and take power from a circuit breaker connected to the battery.
