Re: The Towing thread

I hope that this is the right thread. If not, please redirect me to the correct area.

Anyway, I recently bought my first Jeep, Grand Cherokee Limited. I will also be buying a caravan in the New Year. So, with that in mind I need to install an electric brake controller , rear view camera (to connect to the one on the van) and an Anderson plug to power the van's electrics whilst mobile.

What's the easiest way to run the cables for what I need to do? Do I face the prospect of dismantling the dash to run cables out into the engine bay and down underneath the vehicle? Where do you connect the Anderson plug's cable? What about a relay to switch it when the engine's running/stopped? What do you use to capture the vision from the camera?

I s'pose that I could simply take the car to the auto electrician, assuming that those locally can do this sort of work, and say "here, fit all this stuff" and come back later with a bundle of notes for him.

Re: The Towing thread

Ok you are buying a caravan (travel trailer) and not a Caravan (Chrysler van), correct ? ("van" usually means a powered vehicle here).

Most travel trailers with electric (not surge) brakes use a 7 pin Bargman plug here for power, lights, and brakes. A Jeep that came with the towing package has all of the wiring you need and the TV plug, You just need a controller (Tekonsha is good) and a wiring stub.

If you do not have the factory towng package you will need to add that plus a receiver (factory is best) and wiring harness (may be a connector by the rear axle) terminated by a Bargman.

I added a wireless camera for my travel trailer so did not need more wires. Most use an RCA plug for a video feed.

Re: The Towing thread

Padgett. The OP is in Australia, so the setup is somewhat different for Export models. The Aussie models do not have the trailer plug loom, so you need to hack into the wires at the rear of the car.
To connect an Anderson plug, I found the best way was to run leads directly from the battery, via the driver's side sill and into the boot. From there you will find a few plugs where you can exit the wires and connect to the Anderson plug. I also connected a Projecta isolation switch, but many suggest a dc/dc converter in the van is better.
As for break controllers, suggest either the new Redarc or the Tekonsha. The Tekonsha will fit into the central cubby at the front of the console with a little work. The Redarc will need a hole to be drilled somewhere to mount it.
In regard to a rear view camera for the van, if you want to have it run through the car's screen, you will need to add a kit. Or you can use a second screen, see safetydave.com.au

Thanks Al.

When I got the towbar installed (prior to delivery) I forgot to ask that they install a 12pin plug, so they installed the standard flat 7 pin one.

They could've installed a Redarc controller but I'm told that it's not as efficient as the Tekonsha P3 ones. ie. it's not progressive. Also, the dealer's cost was $600 fitted for the Redarc.

I saw that "dave" website and watched a couple of his videos on rear view cameras. OK for choosing one, but nothing about how to install them, particularly on vans which don't have one.

None of the vans that I looked at which didn't have cameras had any obvious way of fitting a camera and running cabling inside of the van's walls. So, I'll have to consider vans which have them already, and quite a few that we've looked at have them.

Some have separate 4 pin connectors, others have the camera wiring integrated into the trailer plug.

A local dealer of caravans (the ones that you tow and sleep in) has a workshop where I think they have guys who can fit such accessories.

I'm not sure of the requirement for a "DC/DC" converter for the van and connecting into the Anderson plug?

Thanks

The Redarc TowPro is progressive and is only $100 more than a P3. I have a P3 and they are a great controller, but for installation reasons I would buy a TowPro if buying again today.

Using a cable snake, run the cable through/along the drawbar then through/along the chassis rails. At the back of the van install a vertical post for the camera/s on the back bumper. Protect all wiring with split tube/duct/conduit/etc...

There are no pins allocated in the standard for cameras, so you would make your van "special" by using the 12 pin. Use a separate connection.

If the van has a reasonable amount of solar permanently fitted, a DC-DC converter is not really worth the expenditure. It actually requires a fairly detailed review of a caravan's 12v system (along with the car which is in this case a known) to truly determine whether DC-DC conversion is truly necessary.

Cheers,
Steve

I've been towing with the Redarc Towpro for 12 months now. It's a proportional controller - I think that's what you mean by progressive? It's a great controller and a lot less intrusive than the Tekonsha (one little knob as opposed to a large unit). I bought the Redarc on ebay and got my local auto electrician to fit it rather than the dealer, they tend to understand the electrics a lot better plus it should work out a lot cheaper.

cheers
Ian

I would not recommend you run camera wiring via the trailer plug. Best to run them independently. They generally come in 4/5 pin leads. Some cams also incorporate audio.

Some of the vans had cameras but no extra cables or plugs. Just the Anderson and the standard multipin flat plug. I'm guessing that they incorporated the camera link into that.

Anyway, yes, I think that what you suggest is the best way to go. Also, audio is a godsend for the driver listening to his/her guide when backing the van, I understand.

wiring through the firewall

Hi, I have a 2015 GC (Aust spec). Electrician has wired in the towbar & ran the wiring for the electric brake controller (goes externally under the car) up to engine compartment next to the fuses. I need to now run these wires to where I want to mount the P3 controller (will mount in the cubby hole below the radio). I can get access to that. Anyone have any easy way on how to get these wires through the firewall & to that cubbyhole?
Cheers,

Re: The Towing thread

I hate to see auto sparkies running wires under an offroad vehicle. They could have run them internally without too much trouble.
In any event, I believe there is a grommet somewhere behind the glovebox, and another behind the steering.
