Hi all, need some help with sourcing the right wiring loom/harness to retrofit fog lights on my startline Caddy mk4.
Does anyone have a link or part number to the genuine fog light wiring harness? I want them to function as factory fitted fogs, which would then require coding for them to work properly I believe.
Any help is appreciated! Thanks lads

I can make an OEM loom, but you'll need to see if your BCM will support fogs ( needs to be midline or highline)

Re: Mk4 Fog Light Retrofit
Well mine is a startline so not good news . How can I confirm if my BCM supports fogs? Do I need to inspect it physically?tommyzooom wrote: ↑Wed Dec 06, 2023 7:37 pm I can make an OEM loom, but you'll need to see if your BCM will support fogs ( needs to be midline or highline)

Re: Mk4 Fog Light Retrofit
Not sure if this is of any help to you, but my mk4 caddy is also a startline model.
I've been able to fit the factory xenons and code them to my vans bcm.
In the long coding is also the option for front fog lights.
Taken from my vans bcm via obdeleven Pro dongle.
Did not need to change out my bcm which some others talk of doing.

Re: Mk4 Fog Light Retrofit
Thanks for your input, I will make sure to ask my mechanic in January whether my bcm supports fog light installation, as I currently don't have access to vcds or other obd reader.DW2207 wrote: ↑Thu Dec 07, 2023 1:40 pm Not sure if this is of any help to you, but my mk4 caddy is also a startline model.

Re: Mk4 Fog Light Retrofit
Do you have any link where i can get this oem loom mate? I have already bought the lamps, with led bulbs (not sure whether these bulbs are error free), fog light trims and have a front fog capable light switch. Would you also have some wiring instructions on how they would need to be wired please?
