Modifying the windows controller key fob control cable harness for RHD use

  • Hey there. I recently picked up the windows controller for RF (with the control cable in a single kit) for my 2022 RF GT RS. I live in Australia and didn't think to check if that version of the control cable worked for RHD vehicles. From reading a couple of posts here it seems like the recommended thing to do for RHD vehicles is to order the control cable separately with Posi-Tap connectors.

    Since I've already got the harness version of the cable, I thought it would be nice to try and modify the harness to suit my car. I'd kind of prefer a nice clean harness install over using Post-Taps anyway.

    I haven't yet looked at which version of the harness my car uses (2 wire or 3 wire), but if I have the 3 wire version, then I'm assuming I'd need to move a couple of pins, and add an extra pin? Is there perhaps somewhere online I can order one of the connectors to salvage for parts? Even knowing the model number of the connector might help.

    Thanks in advance 👍

  • If you got a cable with 12-pin connectors, it must be made for RHD with 2 wires version.  Check your connector before installation. We ship to RHD country modified cables. It is easy to move pins around. We start adding extra wire to the kit, but we are not sure if you got it.

  • Okay, no worries, thanks for the info. I'll comment back here once I've check what connector the car has. In any case, this is the harness I recieved:

  • Okay, I've had a look at the connector on my car, and while it has the correct number of pins, it seems to be the mirror image of what I need:

    This makes me wonder if I made a mistake by trying to install the controller in the driver's side (right hand) door? The instructions do show the left hand door, but I just assumed it would need to be the driver's door for access to both the driver and passenger window controls?

    Assuming I have the correct door, I suppose all I need to do is rearrange some pins to match the OEM harness. Do I need a special tool for that?

    I tried to take some other photos to show the configuration of my OEM harness:

    Thanks for your help 👍

  • Hey there, sorry to bump, but I didn't get a response and I still need some help. I was wondering if you might be able to tell me:

    1. Which door should this be installed in for RHD cars?
    2. Which pins should I move?
    3. How to de-pin the connectors?


    I tried to poke around in the connectors to see if I could figure out how to de-pin them but didn't have any luck. I've got some de-pinning tools on the way which I'm hoping will help.

  • Okay, I've finally had some success! For anyone who comes across this post later, here's what I had to do:

    • You must make the change above to both sides of the connector.
    • The module gets installed in the driver's side (right hand) door.
    • Get yourself some de-pinning tools - it's a major pain to move the pins otherwise. I used these:
    • For the female side of the connector, I used one de-pin tool to slide between the metal pin and the plastic clip on the side where the wire enters, then used another de-pin tool on the other side to push the pin out.
    • For the male side, I used a de-pin tool to push the plastic clip down from the side opposite the wires, whilst gently pulling the pin out by the wire.
    • I had to install firmware v105 before the fob control started working properly - the open button would close the windows and vice versa.
    • I had to upgrade the firmware on Windows, because at the time of writing, there is a bug with upgrading firmware via macOS.
    • At some point before the firmware upgrade I saw a "Retractable Hardtop System Malfunction" error message in my dash, and the roof refused to open all the way. I also lost the ability to control the passenger's side window. Disconnecting and reconnecting the battery seems to have fixed these issues.


    Hope this helps somebody!
