Where is the loom available from?

You need to make your own up if you don't have it already installed and route it best you can.


I have yet to do this as I am waiting forr all the bits and reserve a few days, but in my head the method would be:

Assume 5m of cable for each as excess can be removed at the final 18 way connector stage. It is cheap enough to look at.
Assume bumper is off and the radar unit is fitted and aligned.
Pre-twist the CAN cables with 1 twist per inch but leave some untwisted as it will maybe be easier to feed through the firewall if not twisted but twist as soon as it pops out the other side.
Do not twist the CAN bus wires with other wires.


1. Take the battery out to access the engine fuse box to put the BATT feed in and the firewall - need a latching spade connector crimped on the end to fit in the empty half of fuse 7.
2. Terminate the GND - need to crimp a eye connector on this.
3. Feed the remaining three cables through the firewall to the passenger compartment.
4. Access the CJB and fit the IGN feed - you need add a pin in the green multi way socket so the connector needs to be disassembled. Fues 6P should already be fitted.
5. Find somewhere to splice into the HS CAN. Twisting remaining cable length if needed.
6. Once all connected, dress/wrap the cables in, working back from the battery box either over the back of the engine bay with the existing loom and down the driver's side (original routing I think) or straight down the passenger side with the bonnet release cable. I will use non-split convoluted tubing to protect the cable.
7. Present the cable to the cross member/radar with enough slack.
8. Make up and connect the 18 way connector for the radar unit. Connections are the following;

Pin 1 = BATT 10A fuse 7E - Purple/Orange 0.75 CSA
Pin 3 = GND - Black 0.5 CSA
Pin 7 = HS CAN L - Yellow/Black 0.35 CSA
Pin 8 = HS CAN H - Yellow/Brown 0.35 CSA
Pin 10 = IGN 5A 6P - White/Red 0.5 CSA

Once all connected and happy...replace the battery, ensure the radar is recognised, program and update FW as required.
Replace the bumper and go for a drive to calibrate/test it.

So a fair bit of manual work taking things out/off but electrically pretty simple.
It might be possible to pre-make the cable but the pin for the CJB will still need to be crimped on so better to make it as you go to get it all neat.

Feel free to comment as it is v1.0

I was able to buy a DPLA9G768AD today at a decent price. I have the wiring in place so I’ll be giving it a go over the next few weeks.

I see that, thanks! I guess my question should have been more direct: Has anyone bought the switch pack from anywhere other than the main dealer at £138 + VAT?
