Removed the front bumper of my L405 to install the adaptive cruise control module and spotted this unused wiring loom behind the grille, right next to the horns.

Anyone know what it's for? Didn't think to look for a part number at the time.

Winch?

Could be for additional fans in hot climate. There is nothing that can't be fixed with a hammer😜😜

How do you guys find out what can be retrofitted?
What about lane assist?

There's a master thread somewhere with a list of all the things that can be retrofitted to date. Can't seem to find it at the moment.

Specifically for the Adaptive Cruise Control, I followed this thread to figure out it was possible. 2021 P525 | Eiger Gray

I'm half way through the modification at the moment. Information I'm using is:

1. Radar Distance sensing unit
• PN - LR062658
• Bought Delphi JS301111640078
• Described as and looks identical to L494 cruise control radar sensor, FPLA-9G768-AC

2. Bracket
• PN – LR033405 or LR060076
• Bought from LR (£16.33)

3. Steering wheel switch

4. Programming – Get into "Full CCF Function"
1. Speed control - Current: Adaptive cruise control is fitted
2. Adaptive speed control ECU - Current: North America, Canada, Mexico, Australia
3. Adaptive speed control ECU – Current: standard blockage level -40dB
4. Collision mitigation by braking – Current: Fitted
5. Standard speed control display type – Current: Adaptive speed control full display plus priority messages
6. Speed control - Current: Adaptive cruise control with queue assist
7. Adaptive cruise control indication in instrument cluster - Current: Enabled
8. Speed control – Current: Adaptive speed control, stop and go
9. Collision mitigation by braking – Current: Collision mitigation by braking GEN3
10. Forward collision warning – Current: Forward collision warning GEN3
11. Front crash sensing system – Current: Front crash sensing system – upfront sensor
Then: instigate sensor alignment

Hardware is all in, and just working on the programming. Trying to understand JLR SDD enough to see if that will allow me to get into the Cruise Control Programming. Apparently someone has done it via IID, or alternatively take it to a local (good) specialist with access to programming. Current:

Did my programming with the Gap IID tool. Very easy process, but you have to contact GAP for them to give the tool access to the full CCF for modification. 2021 P525 | Eiger Gray
