I’m looking into adding LDW and TSR to my 2016 L405. I’ve sourced a high line mirror that is supposed to work on the 2016 models as the earlier model ones do not work correctly. My trunk switch has the 2 wire harnesses for it and not the single plug. My question is if I order a new switch for the trunk and has LDW switch as well comes it come with the factory adapter plug? I’ve looked for some on eBay but none of them have the adapter plugs which I would need.

hmmm - seems I have seen this recently

It’s going good, and I now have LDW and TSR retrofitted to my16 l405. The LDW switch is not needed and Pat from Gap got me all taken care of!

Do you have a part number for the mirror?

What year Rover you have as it will make a difference as the Can Bus changed

It’s a 2016 Model year.

GPLA-17E678-HC is the part number for my US 2016. It was removed from a 2016 RRS

Many thanks
