Video Transcript for Pollak 6 Pole Round Pin Trailer Wiring Connector Installation

Today we're going to review part number PK11604. This is the Pollak 6-Pole, Round Pin Trailer Wiring Connector. Now, to help us with our review, we're also going to install it on part number DW04906-1 from Deka. This is our Jacketed 6-Wire. All right, this is our 6-Pole Connector. Got a dye-cast body and on the end here is ABS with brass inserts.

Pretty simple. It's been around for a very long time. Let's go ahead and take it apart. When we do, we want to make sure that our clamp is opened up completely so we can eventually run our cable through. We'll go to the other side and go ahead a remove the screw that holds the plastic insert in place.

Definitely want to keep this screw in a safe place until you're ready to re-install it. Trust me, I've lost a lot of these. Go ahead and pull it apart and see your terminals on the inside. Then the wires are held in place by small set screws that also use a Philips screwdriver. Let's take a look on the inside edge here, you can see the labels are just letters. See G for ground.

You should also see a T for a running light circuit, L for left turn, and a R for right turn. The last 2 will S. Typically that's used for brakes or it could be used for a 12-volt power supply to your trailer. Same thing for A, brakes or a 12-volt power supply. Also it depends on how your trailer's manufactured.

The hot lead or the brake lead could be interchanged. It happens quite frequently. Let's go ahead and run our cable through our housing and we actually have our wires already stripped and ready to go. First, let's go ahead and start with the center one. I typically like to use that for my 12-volt power supply, so we're going to use our red wire on our cable for that. We'll go ahead and, it's a good idea make sure the strands of wire are twisted tight, we'll go ahead and run it into place and then tighten up the set screw. You want this nice and snug. You dont want to crush it. All right, let's go ahead and do our ground. Let's go ahead and work our way around. Next one will be L, for our left turn. We'll go ahead and run our yellow wire to that. Our green wire will go to the pin labeled R for right turn. The next one's labeled S and I like to use that for the brake signal going out to our trailer, so on a cable I like to use black. Of course, the last one will be labeled T and that will be our running light circuit. You can think of it as trailer marker lights. Make sure nothing's touching, then we can go ahead and slide our cover back into place. Bring the screw back from its safe place that you remember put it to, right Then we can go ahead and tighten down our clamp for our cable. Again, this just needs to be snug. You dont want to crush the cable. Okay, now with our 2 pieces joined together, now would be a good time to add this to a trailer. That will finish it for part number PK11604 from Pollak, their 6-Pole, Round Pin Trailer Wiring Connector and also our Jacketed 6-wire, part number D04906-1. .

I replaced the connector ends on the cable that hooks from my motor home to my tow vehicle. The PK11604 are better made product than the original connectors. A machine screw is used to hold the Receptial in place as compared to the original which had a flush head wood screw. The terminal hold down screws are stronger and easy to work with when installing the wires. 600474

Ask the Experts about this Pollak Wiring

  • How to Test Old Trailer Wiring to Find Out What Each Wire/Circuit Does
    You have discovered the "dirty little secret" of trailer wiring: wire colors are not a consistent and reliable way to figure out what each one does! But it is easy enough to check this simply by applying 12V power to each circuit and noting what function on the trailer comes on. It is easiest to use your vehicle battery (or a well-charged spare battery) along with a set of jumper cables and two lengths of wire. This makes it simple to apply +12V power to each circuit on the trailer (one...

  • Troubleshooting Trailer Light Running Light Circuit Not Functioning
    First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector are...

  • Testing the Trailer Wires for Function Using a Circuit Tester on a Horse Trailer
    My suggestion is to test the wires for function with the trailer connected to the tow vehicle. You will need a circuit tester, like # 40376, or a multimeter if you have one. You can start with any function, but I recommend starting with the left turn signal. It would help to have someone sit in the tow vehicle and engage the functions while you test the wires on the trailer. With the left blinker on, probe the wires until you find the one that carries a signal in unison with the left...

  • Tekonsha Brake Controller # 90885-3015P Recommendation for a 2003 GMC Yukon XL
    It sounds like you are in need of a brake controller. You would not want full 12 volts getting applied to your trailer brakes at the exact moment you apply your Yukon brakes otherwise your trailer brakes would lock up every time you touched the brakes. The tow package that came with your 2003 GMC Yukon XL gives you most of the wiring for towing a trailer but will not give you everything you would need to appropriately apply the brakes that are on your trailer. For that you will need...

  • Troubleshooting 6-way Trailer Connector on 1999 Ford F350 Flatbed Truck
    There are actually two different accepted methods of wiring a 6-way trailer connector. The center pin on a 6-way trailer connector usually carries the 12-volt accessory circuit that is used for any trailer mounted accessories that might need a power feed, although sometimes it can be wired so it carries the output voltage from the brake controller to the trailer brakes. If you take a look at the FAQ article I have linked you to, you can see a wiring diagram showing how a 6-way should...

    From what I could find online it looks like you can flat tow your 2013 Suzuki Grand Vitara as long as it is a 4WD with a transfer switch. If it is a 4WD without a transfer switch then you need to use a trailer to keep all of the wheels off of the ground. For a 2WD you can tow it using a tow dolly with the rear wheels off of the ground. You will want to verify this and specific instructions in your copy of the owner's manual. If you have a 2WD then I recommend using the Roadmaster Tow...

  • How to Wire 4 Trailer Wires Into the Pollak 6-Pole Trailer Connector
    Typically, the wire colors are brown for running lights, green for right turn and brake lights, and yellow for left turn and brake lights. White is ground. To confirm this on a trailer you can trace the wires back to see where they terminate or take a separate 12 volt battery and use it to power each wire to see what lights up.

For an adapter you would want the part # 30637. This will plug into the 4-way and will convert the taillight signal to a 6-way. To activate the power circuit for the camper battery you will need to run the black wire from this adapter to the positive post of the truck battery...

  • How to Convert a Military Wired Trailer to a 6-way Civilian Trailer Connector
    I wish we had an adapter that would allow you to tow your military trailer with your vehicle that has a 6-way but we do not. What you could do is cut off the military connection and then wire up a 6-way in place of it. For that you would need a Pollak 6-Pole # PK11604 and taillight converter # 118158. Before you cut off the connector you will want to pick out the following wires from the back of the military connector and label them somehow. Masking tape and a marker would do well. J,...

  • How to Rewire an Old Cattle Trailer
    It sounds like you are on the right track to rewire your cattle trailer. You are correct about the wire colors on the 7-way connector that you purchased. The colors that you see on the 7-way connector are typical for RV style trailers rather than utility, cargo, or livestock style trailers. The black wire should be connected to the terminal in the 7-way connector labeled black. This is the terminal in the 11 oclock position when you are looking at the back of the trailer connector (see...

  • Running Lights on Trailer Stay On All the Time
    This sounds like the problem could be a short or possibly ground related but based on what you have said a ground is much less likely. Look for any pinched or frayed wires on the trailer and fix as needed. This could cause a short resulting in constant power draw. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side...

  • Tow Bar Wiring From a 6-Round Connector to a 4-Round Connector

    The 6-wire and the 7-wire connectors will have the same color codes on six of the wires. The green wire is right turn/brake, the yellow wire is left turn/brake, the white wire is the ground, the brown wire is the taillights, the blue wire is electric brakes, and the black wire is the 12v power. The 7-way motorhome connector will have an extra auxiliary wire (purple) on the center pin that is used for reverse lights, 12v power, or reverse lockout for trailer brakes. There are two...

    Sounds like your trailer wiring does not have a ground circuit for it's connector. The easy solution for that is to run a wire from the ground pin of the connector to the trailer's frame.

  • Installing a 7-Way Trailer Connector on a Trailer with 6 Wires
    You can certainly add a 7-way trailer connector to your trailer with 6 wires. You would simply have 1 pin on the 7-way connector that did not function. I recommend adding a 7-way molded trailer wire connector like part # H20046, and a junction box like part # 38656. We do this on all of our trailers and our customers trailers and it will make future wire maintenance much easier. I have attached an installation video of these two parts for you to check out. Once you have all of your parts,...

    First you will want a new 6-way like the Hopkins 6-Way Molded Connector, # H20036. Installing the 6-way plug will be made easier by using a junction box such as # 38656. This box mounts to the trailer frame and serves as a connection point between the trailer's original wiring and the new 6-way. Also you will want some Deka jacketed 2 wire, 10 gauge, brake wire # 10-2-1 to run the brake output circuit from the junction box to the brake assemblies as well as some Deka 16-gauge bonded 4-wire...

  • Why Do the Trailer Brakes Lock Up When 6-Way Connector Is Plugged Into Ford Truck
    A 6-Way round pole connector can be wired one of two ways; with the center pole as the 12 volt hot lead, or as the brake. Having the center pole as the 12 volt hot lead is probably most common. In your case, the 6-Way round connector on your Dodge is probably wired with the center pole as the brake lead. The Ford is probably wired with the center pole for the 12 volt power. When you plug in the connector to your trailer and the center is 12 volt power it is just going to lock up the...

Which leaves us with the two black wires. There are a couple options for determining what the black wires are for. You could get a 12 volt battery like a car battery and run a jumper wire from there to black wires to see what functions on the trailer activate. Or, you could trace the wires back to see where they terminate. One...

  • Troubleshooting Trailer Brakes that Lock Up When Connected to Trailer Wiring
    This is a fairly common problem for trailer setups that use 6-way connectors like the # PK11604 that you referenced. The issue is that there is two accepted ways the connector can be wired up. The only difference between the two setup is that the brake output circuit and the 12 volt accessory circuits are swapped. It sounds like your vehicle is wired one way and the trailer is wired the other way. What you will need to do is swap the two circuits on either the trailer or the truck....
