This Old Trailer : Replacing a 7-Pole Connector

Video Transcript for This Old Trailer : Replacing a 7-Pole Connector

Today on This Old Trailer we are going to diagnose some wiring problems. The problem with this trailer is that when you plug the trailer into the vehicle none of the lights work. It could be a variety of problems but the first thing we are going to do is start from the front and work our way back. Just to make sure there is nothing wrong with the towing vehicle use an independent power source to power up the trailer just to make sure. Then we will turn on the lights and check in the back. We have got our power supply on and it looks like there is nothing working in the back and also it looks like the running lights were not working either. Lets go back up to the front and check the connector. 00:33

First off we will inspect the connector itself. It looks like it has been around awhile and you can tell the leads on here, kind of a dark color, so that tells you that it is oxidized and will not allow current to pass through very easy. An easy trick is to maybe scratch it and see if it comes back to life. We are going to use a small screwdriver and kind of go in there and clean out the tabs and see if we can get anything working after this. We will reconnect to the power supply and check again. With that simple little test we have got the running lights working so lets check the rest of the trailer. It looks like we have got one tail light in the back that is not working so we have got our running lights. Lets check the turn signals just to make sure. It looks like our left turn came to life so we are good there. Lets try the right turn. We do not have anything there either so it could be A: the connector, or B: something is wrong with the light. Since the connector is pretty dirty anyway lets replace that connector and start fresh from there. 01:37

To take apart the connector, we have the screw in the back to remove and a little set screw up towards the front to the remove. Then we will cut away some electrical tape and try to slide the cable in and out. Push it out the front. We have got a good look inside of here. All of the connections are pretty tight but everything is starting to rust up and start to corrode just a little bit so it is probably a good idea to replace the connector anyway. This is our new 7-pole connector and we are going to be using part number PK12706. We will assemble the connector like we did before and we are going to take our wires and push them back through to the front and work it in. Lets get the wires in order here. You can twist these and put them into the clamps in the connector like they were originally or you can put on some small ring terminals too which I think that is what we will do. Now we will connect our wires to our 7-pole. If you noticed on the 7-pole itself that all of the little tabs or lugs are all labeled different colors. It is not going to be a color for color match because the colors on here are going to be different from the colors on the trailer wire harness. 03:19

We will start off by what color we are going to use and we will show you where to go on the 7-pole. We will start off with the only one that actually matches and that is going to be white. So we are going to put white to white on the 7-pole. When you install it with the ring terminals, have them facing down like this so you have it going this way all the way around they will fit in the connector as well. We will move on to our next color. This is going to be the brown wire and the brown wire on the trailer is going to be the running light circuit and the running lights on the 7-pole connector is going to be green. We will work with green on the trailer wire and that is going to be right turn so the right turn is going to be brown on the 7-pole connector. Our last color yellow that is left turn on the trailer and it is going to be red on the 7-pole. Lets push everything back together and install a little set screw. Move to the back side here and put the clamp and set screw in and it is a nice tight connection. Place some electrical tape here. Lets plug this back into our power supply and see if we get any better results. Lets apply power to see what we get. First off we will try running lights and it looks like both of them are working. Now try the brake lights, that is good. Then we will try our right turn signal and that looks good. Try the left turn signal. Okay it looks like everything works. There you have it for replacing a 7-pole connector on This Old Trailer using part number PK12706.
