Thanks for the vid. I’ve just fitted my tow bar today and am tackling the wiring tomorrow. Great to see where to pick up the wires. My only thing I started doing is I don’t wire the fog I put it to the reverse lights and I’ve reverse lights on my trailers.
Hi Timothy my van is 2013. My bypass relay only needed one brake and one dip light the other wire is just rolled up and taped. When driving with no trailer the relay clicks and makes a lot of noise so I am going to put a switch to turn it of while not pulling a trailer as it is annoying me. I used that live as it comes straight from the battery. I used good heavy duty cable not the crap that came with the tow bar because I also added a 12volt socket so needed to make sure I had plenty power. Handy for electric cooler boxes drill chargers what ever. Thanks for the comment.
The video is very useful as I am doing this exact job now. The only thing I would say is that you should not wire the 12v feed from a wire in the harness. That wire will be fed by its own fuse so there is the danger of overloading the original fuse. If you follow that harness forward you will find a flexible rubber bulkhead seal. Take a long shaft cross head screwdriver and follow the harness. Push the screwdriver past the seal. Open the bonnet and remove the battery. Remove the battery box. Now you should see your screwdriver. Push the feed wire past the screwdriver and remove the screwdriver. Fit the wire to the battery terminal nut (M6). Make sure the fuse is close to the terminal. I tie wrapped mine to the main power cable.
Hi, I think you are supposed to wire up the left and right tail lights separately, that's why they have separate pins on the socket and plug. The reason is that you should be able to switch each side, left or right, separately as parking lights. If you wire both trailer tail lights from one side you will either get both trailer tail lights on or no trailer tail lights on when using the parking light function. So you should have had a three (3) core cable coming over from the right side of your vehicle. One wire for the fog light, one wire for the right hand indicator and one wire for the right hand tail light. Only then would your wiring be fully legal, and road safe.
Hi, I have caddy from 2011 and I need help with electric parts towbar, I bought from westfalia and all the wire is going direcly to the security panel and I'm not sure 100% where to conect
Can anybody tell me if this works on a 2012 caddy? Would I need anything else done after installing this kit or will it be good to tow a trailer as soon as the wiring is completed. Thanks
eric mourinho it basically stops the light on the dash that says you have a blown bulb which is what happens if you wore directly to the vehicle. So using a bypass relay separates the van lighting wiring circuit from the trailer lighting. Thanks for the comment like and subscribe if you liked the video please.
Helpful video but i am still having problems :(, All lights on trailer and van work correctly and i have the same bypass relay as this video - wired and fused directly to battery, BUT i still have a light fault on dash, could this be a faulty relay? i tested everything before permanently connecting wires and had no faults then, can anyone help!! PLEASE??
RyanGriffiths have you check all the bulbs are working seams stupid but could be as simple as that if it was perfect before you hard wired it in. Caddy’s if it is one have problems with the connections on the front indicators. Have you tried plugging in to a diagnostic tool to see what the fault is also could help.
what year is your Caddy? Mines a 2016, do I still need to do all this? I don't mind having a go at anything but electrics I hate, great video but still leaves me a little unsure to doing this myself.
That caddy was 2016. Yes u need it on your caddy. Electrics are tricky I wouldn’t do it unless u are confident. Please subscribe and like the video. Thanks
@@bobsvidz7181 I was just about to buy a tow bar and electric kit but unsure which one I need, they are saying -'with bypass' £30 and 'vehicle specific' £100. Do you know which I need mate?
kristof vermeulen hi. Yes it does is why u need to do this. Other wise u will have a light in the dash for a blown bulb always when the trailer is connected.
Really helpful, thanks for your post. I was wondering tho, given the constant vibration factor, would it be useful to use both heatshrink AND then wrap with electrical tape too to avaoid any chance of a short to the chassis? Nice work bobs vidz!
Bob what year is your van? Mine is 2014 hitch and relay should be on the way Monday I will be taking a live from the fuse box. Just wondering does only one feed for the brake need to be brought to the relay for both brake lights to work on the trailer? Great video again, thanks :-)
+mmc 10 that just means there is a bulb in the van not working somewhere or maybe an led not suitable. Usually it's the rear number plate light or front indicators that give trouble. It won't do any more harm I would think but not a good way of doing it really. Hope this helps thanks for the comments.
Lone Wolf basically if you wire the Towbar up direct in a modern vehicle the light for a blown bulb will be illuminated on the dash panel ever time you connect trailer lights. So this uses a relay to keep them separate from the vans electrical system therefore stopping this problem hope this helps. Thanks for the comment like share subscribe if you like what you.

thanks for the input. hope the video was of help.
great comment.. some trailers don't have fog lights! otherwise you're spot on..
I tried connecting it without the bypass unit and it wasn't working properly. I'm guessing it will not work without this until
I just like to say thank you for this video it meger help me to fix mine saved me like £40 to fix it

Great vid budd,, can u tell me wot size (thikness) was ur permanent live cable was please,, cheers 👍
Can’t remember sorry. Thanks for the comment Please like the video and subscribe.
Thanks for putting this video up.
what type of wire did you use for the power from front of van to bypass relay,good upload lad
I have the same relay.. mine makes a clicking sound when in use... Is that normal?
Yes that is normal. Thanks for comment please like the video and subscribe helps a lot.
Any idea how to wire one ov theses to an Audi a5
The basic principle is the same. Wire the box in to the back light and find power for it at the battery hope that helps.
I just subscribed because of this video thanks
Aaron regan thanks much appreciated hope the video helped.

Yes do the wiring and fit a tow bar off u go 👍
Thanks buddy
If u don't use tailer do I need it. I'm only mounting a bike on tobar bike rack ya see.

So what exactly does it bypass then.

bobs vidz ok i get it now did you feed it with a 4mm or 2.5 and where did you get that relay
eric mourinho it generally comes as a kit on eBay or other websites etc I used 3mm for the 12v I think. With a fuse which is a MUST very important.

Inhave a problem, when i turn on my reverse light it stays on till i turn on my driving lights and then it switches off
Very informative, cheers Bob. 👍

Does youre car have canbus?
kristof vermeulen hi. Yes it does is why u need to do this. Other wise u will have a light in the dash for a blown bulb always when the trailer is connected.
I have bought this module to. How do i know what wire a need to connect on the light? Can i measure it?

Very informative video but those blue clips have a high failure rate
I didn’t use them just showed them as they came in the kit. Like subscribe please thanks for the comment.
Do you need relay for 05 caddy?Cheers
Ya u will need one. Otherwise it will bring the bulb light up on the dash as mate.
My bulb light is always on on the dash..whatever's wrong. Would it do any more harm?

bobs vidz so it's only for if using trailer
Lone Wolf yes only for lights on toe bar or some bike racks that have lights etc.
I'm lucky. The original owner had one fitted in factory
Very helpful, many thanks
