      Access through fire wall on XC60 for trailer brake controller cabling

      Hi, I was hoping someone might have had to try and run cables through the firewall and tell me the best place to do this - I need to wire up a trailer brake controller and have to run cabling direct from battery through firewall to the controller that mounts near the driver and then sends this braking signal to the rear trailer hitch connection - naturally I do not want to mess with the sealing and integrity of the cables that run through to the engine bay.
      thanks in advance for any help or suggestion

      You should have wiring already there for this in the rear cargo area behind a pop out panel near the right rear wheel-well. There is a connector for the OEM hitch.

      Hi Stewbydog, I have fitted a brake controller to mine and mounted it under the steering wheel. Where in Australia are you located?

      Regards,

      Michael

      Volvo publishes the installation manuals for accessories here:

      http://accessories.volvocars.com

      Find a similar accessory and you can get a lot of insight into things like running
      wires, pulling trim, etc. Examle (see pags marked 75 and 76):

      Hi Michael, I would greatly appreciate any help/suggestions for running brake controller wires from battery to rear of trailer connection - I do have the car booked into a local trailer company who said they could do it but I fear they are no familiar with the XC60 install. I have just had the trailer module fixed after I plugged it onto the trailer and it fried the trailer module - my dealer had to replace the module and took 5 hours to get it reconfigured and running again so I am very wary about it happening again.
      I am in Brisvegas north suburbs
      Thanks again Stew

      per an earlier post, all the connections you need are in the back of the vehicle. Not having to run to the battery saved me much on the expected labor for my install.

      Thanks for the tip - I will look to see if this is the same for r/h drive cars

      Hi Marcel- thanks for the link to the suggestion that there is a foam plug - I shall look tomorrow and hope that r/h drive cars are the same as you suggest - may not be as we are not offered a manual drive car in Australia
      Cheers

      Hello all who may be interested - the brake controller install is now complete - the local trailer business had it for a day and decided that it was all too hard?? apologised and gave the car back - they looked at the 13pin connector that the dealership had installed and found it to be a sealed unit - they contacted the local Volvo dealer and they gave the story that they can only fit trailer brake controllers and wanted $1450 to do the job.
      I returned home peeved off so set about doing it myself - I took mark-sf idea to use the 12vdc source that runs to the 13 pin trailer connector and ran this to the drivers side of the car under the carpets - not a difficult job just time consuming.
      The biggest problem was that I found the 13 to 7 pin adaptor that comes with the car supplies the r/h park light to the pin 5 needed to run the "Service brake" on all 7 pin connections - someone really didn't think about this before manufacturing it.
      I had to dig out the silicon sealant that is used to seal the back of the 13 pin connector and run the service brake wire to this - sounds confusing I know. anyway all is working and having family holidays in our new camper. Thanks all for your input.
      Cheers Stewbydog

      Stewbydog, I am getting my 2009 XC60 (Australian) ready for towing. I have the 7 pin flat factory connector. Just figured out tonight that the dealer left the blue (electric brake wire, pin 5) unterminated. Therefore, it will be easy to connect in the brake signal. Can you give any more detail on where you routed your back to front wires under the carpets. I am trying to figure out the best way to this myself. Since I only have the 7 pin trailer plug, I can use the 11D/A9 fuse for my brake controller power. Did you run the stop signal, power and electric brake signals from the back to the front?

      This was a great resource.
      I can see where I would pull off the 12V, but I need to get a "Brake Applied" signal, and the control module sends out 12V pulses to look for a bulb out. I was hoping for a brake controller plug under the dash with the signal from the brake pedal. I think Toyotas have this kind of plug... Looking for something like this on the Volvo up front under the dash...(via online resources).

      Going with RF Trailer Brake Controller

      I just purchased a "new to me" 2011 XC60 with the factory tow package installed. I went on Amazon and ordered an RF trailer brake controller, as I decided I didn't want to tear up the upholstery or continue digging into the wiring diagrams due to Volvo not giving us a nice connector under the dash and at the rear of the vehicle as I would have in a Toyota 4Runner,Sienna, Pick-up. I expect that I'll have the brake controller tomorrow, and will be hooking up my rig for the first time and taking it to some CAT scales on the weekend to get a baseline on the axle and tongue weights. (My travel trailer is 1800# empty 3500# gross).

      Tekonsha 90250 Prodigy RF brake Controller $308.95.
