My bike was stolen and it had the connector for my repco tagalong bike trailer on it. Im having trouble finding a new connector for my trailer. Where can I find one please

Hi Bruce,

Let's back up for a second. Are you wired like this?

Using an inexpensive 12 V test light / tester like the one below, connect the clip to a good ground on the vehicle. Then with someone else working



the brakes, turn signals, lights, etc. ONE AT A TIME, you should push the point end of the tester into the corresponding connection on the VEHICLE. Only one connection should have power at any given time. Once you have verified that the correct & only connection has power at the right time - you can move to the trailer end of the wiring. If you can not verify the vehicle plug is working correctly - you'll have to get it working right before continuing. These connectors can develop problems over time and may need servicing.

If the trailer still has issues, check ground by uncoupling the trailer hitch from the ball on the vehicle. Keep the 7 pin connector from the trailer plugged into the vehicle and turn on the vehicle lights / have an assistant step on the brake. Connect the clip to the frame of the trailer and push the point to a good ground location on the vehicle. If the tester lights up - you have a bad ground wire between the vehicle wiring to the jack and the trailer frame somewhere. The lighting is relying on the contact between the ball & hitch for ground and could be causing the problem.

Check all the bulbs to make sure that they are the right ones and if the offset bayonet base type - inserted properly. Inspect lamp sockets, wiring and ground leads at each lamp socket. You can also disconnect a wire from a point that is common to left and right sides of the trailer to help narrow down where to look on the trailer for the trouble. If you disconnect a wire going to the left side and everything on the right works as expected when trying all the lights, brakes, etc. then you know the problem is probably on the left side. Reconnect the left side and disconnect the right side and test again. It is a process of elimination when you can't see anything obvious. Keep disconnecting 1/2 of the side that is causing trouble until you find the problem.

You can purchase a 7 wire vehicle jack test plug like this to quickly diagnose the vehicle for less than $10. It will indicate on the LEDs the power seen from the vehicle.

It's possible these are two separate problems. You will have to find out why the power is not reaching the license plate lamp assembly, and this means tracing the circuit. Check for power and ground at the lamp. You will have to identify the correct wires and follow them back toward the fuse to find the problem. A wiring diagram will make it much easier to solve.
Same with the trailer connector. If it's not working, I assume you mean there is no power when you plug in your trailer. You will have to figure out which wire is supposed to supply battery voltage and why it isn't. Are there any broken wires? Corrosion? Does the trailer connector have any connection to the license plate lamps? (It shouldn't.)

I also had the same problem with my 2008 grand caravan. It turned out to be a bad ground wire. A real difficult thing to find. You just might want to replace all of the wires or better still replace the entire harness it will save you a lot of trouble

Pull one of your tailights on truck, and find wire to back-up on it, then run jumper down to 7 pin plug. Might save a lot of trouble/time.

If the blinker is working on the truck then fuse is good, this sounds like a bad bulb or connection to the light, the brake and signal use the same filement in the bulb. check the bulb first, next thing to determine if its the trailer wiring or the truck socket, use a testlight and test the connector or the wire at the trailer connector and see if there power in the wire, but check close to connector if theres power coming out the connector then it in the trailer wiring or bulb,. also im not sure what this trailer turn relay rh is that you speak off. the only thing i could think of is to converter the signal and brake on the truck to operate the same bulb on the trailer, if this is what you installed then check that wiring also as the controls the lights to the trailer, but if this truck was built with the tow package then it should of be wiring already for this. here a good site to help you with the wiring as this gets hard to explain over the computer, but again test the tow connector on the truck first with a testlight, this way you will be able to see if it the trailer wiring or the truck wiring to connector. google trailerlightwiring. good day. let me know if you have any other questions.

Check Fuses # 36 & 42, these are the fuses for the trailer tow adapter ( separated from the trucks.

If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

You'll need to disconnect the wires from either the truck connector or the trailer connector...
I highly suggest purchasing a voltage checker- it looks like a screwdriver with a pigtail of wire with an alligator clip on the end. The tip of the 'screwdriver' has a point for probing. The light in the probe will light up...makes it easy to trouble shoot without a helper behind the trailer.
Hook the aligator clip to a good positive grounding point on the bumper or frame(not painted).
then pin by pin on the truck connection, stick the probe on each terminal tab.. and write a simple diagram where you find brake, tail, backup, etc...
Then i'd suggest, taking the connector off of your trailer, exposing the wire ends.
Run again thru your diagram and turn on each light of the truck. As you do, touch the wires from the trailer to that specific terminal. (make sure your ground wire is attached on the trailer) you can mark each wire with a piece of tape and label it which is which.
then simply attach your trailer wires according to your diagram to the terminals in the connector... that should get you in business..
hope that makes sense...
That way if the factory wiring harness remains the same, you'll be able to use it with other trailers if the need arises..

most of these trucks came with the wiring harness for trailers already there,look in the back whre the wires feed the rear lights,you should find a connector there, just go to your local parts place and tell them you need the trailer connector for your truck, should just plug in. if you need more help let me know Ray

use the tow connector located behind the tire jack mount at the rear :)

7 way connector, running lights, including license plate light, should be a brown wire. Check the back of the plug receiver on the truck, u are going to have to follow it to see if it's mashed, cut, not connected properly to connector, or loose, corroded, or dirty connections at any splice. That should be the problem. Let me know what u find.
