I’m trying to retrofit fog lights to a 2013 lounge. I have some lights and the crossover loom but can’t locate the car loom plug. Before I pull the bumper off and then possible take the switch relay fuse route, could anyone with fog lights installed take a picture of where the fog loom split foo from the car? I believe it’s near the horn but can’t find a likely candidate so mine may not have it.
Any chance of help with a picture? The only one I can find gives no clue where it exits the main loom.
TIA

Bear in mind that - even if the loom is there - the lights are controlled by the body computer, it's not a simple switch/fuse/relay job. Unless you have some way to reprogram the BCM to accept the switch input, it'd be easier to just run your own switch + fuse and wiring.

I should be ok with carrying out a Proxi Align, if I have the loom?

Where this one May originate I believe.
Phot from the original fo light installation thread on this forum

Proxi alignment is for adding canbus modules to the set up or recognising all the modules in the system.

Installing fog lights does not add any additional canbus modules. The body computer also does not recognise the presence or absence of foglights.

However many systems even without the wiring will still have the coding for fog lights.

If the wiring from the body computer is not there then it’s going to be incredibly difficult to add them.

Best thing you could do is wire the lights into the battery with an aftermarket switch on the dash.

Yes indeed, I understand the process to activate the front fog lights, although it activates electronic options is still a proxi alignment function.In this case there appears to be 2 loom configs, one with , one without extra spurs. In my case I’ve found mine has not the loom though it is a lounge, relay T14 or fuse F30 which would feed the fog lights if they were installed ( nor the pins in the underbonnet fuse box)
Guess I’ll go for a traditional switch relay option

No it’s not !

If the wiring is there you just plug in the lights and go.

If the wiring is not there you could theoretically add all the wires needed manually to the loom put in the appropriate buttons and it would work assuming your body computer is preprogrammed to have fog lights.

If the body computer is not preprogrammed then it’s likely that it also does not have the internal electronic bits to drive fog lights. There is no situation where proxi alignment would do anything to aid the function of fog lights, and you would need a new body computer.

To be honest the fog lights are so terrible with very poor output and they scatter the light a few inches in front of the bumper they don’t really do anything.

If you’re still desperate to install them and have them working then you’d be best off forgoing the body computer and just install something like this with the original button for the dash https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/162905578048

But they do look cool

Sorta

Only If you’re on of those people who like to drive around with them switched on all the time. Maybe stick some coloured bulbs in

Mmmm coloured bulbs, good plan

You can get yellow tinted ones? To look European?

If you have a car without foglights you may still have the loom. It’s obvious and is next to the headlight/drl plugs. If not you will have to run your own cable.

On cars where it is present, you don’t need to change the instrument panel switches but you have to activate it on the body computer using MES. You can swap over switches if you want but that just has the two symbols rather than just the rear one.

Apologies Smeagol, I didn’t know the 500 only had one button for this, I, use to fiats having a button for the back and another for the front.

It’s all cool, in my case a Lounge spec but no loom relay or Fuse so activating it a moot point.
Works out well though as I can add a separate button and have them both on when it’s not foggy and with yellow bulbs ?
The bulbs and loom are from a later car so will need some tweaking anyway and I’m not sure if they are LED as I can’t see how you’d change any bulb. Saves any can bus issues ?

I have retro fitted fog lights to our Lounge and you do have to perform the proxy alignment because the fog light switch will have a different operating function, instead of without front fogs it will be 1 press = on, 2nd press = off, the 2nd press will now have a different function.

Front fogs did not work until they were enabled.

Here is what I wrote in 2014

Thank you ashmj, yes it was your article inspired me to try it.
After much hunting I found out although I have a lounge it has the lower loom spec and doesn’t have the plug in place for the fogs(not fuse or relay provisions) no idea how they select what loom they fit.
At least if I go traditional I can do as AndyRKett recommended and drive around with coloured ones on all day?

Out of the 43 500s I’ve had, apart from the very few that have had foglights, probably 4 or 5 had the loom. Seems random and maybe what they had in the parts bin at the time of manufacture.
