Technical Rear lights wiring RHD to LHD

[euroben]

View attachment 458805

This diagram is a RHD wiring, the entire loom (both fog + reverse) on one diagram.

Rear fog light:
View attachment 458806
Pin 1 is +12V, pin 2 (black) is earth.

Reversing light:
View attachment 458807
Pin 1 is +12 V, pin 2 (black) is earth.

Can't find the explanation of the HV and MH colours. I think the M stands for brown, but not sure. V could stand for Violet.

I saw somewhere on the forum those colour codings.

Both connectors should be the same.

So it seems both are wired the same and canbus controlled so I may well be able to install the new lenses and then swap in MES. Thank you for all your help

I too had a look on eLearn...
The fog light is indeed canbus controlled (and so allows the system to use one switch for both front and rear fogs, only if the main lights are on, via various 'logic' tests).

But it seems the reverse light is just a real switch and a hard wired connection all the way through to the light at the back of the car (via a few plugs and sockets along the way), so altering the lights via a reprogramming isn't going to work. (there is though a link to the BCM from the reverse wiring which is used to turn on the rear wiper when you engage reverse if the front ones are on, and operate the parking sensors if fitted)

The plugs are identical on both lights: so, the neatest solution is to take the (long) wire out from the RHD fog light, roll it up and plug it into the new LHD light. For the reverse, obtain an inline plug (or socket) that will go into the existing plug on the reverse light wiring, and make a new length of cable with a second plug at the other end to go into the new LHD reverse. That can just run along inside the bumper, cable-tied to teh crash bar. That way, no wires are physically cut and so it can all be undone if need be at a later date. The plugs and suitable crimp tool are all available via Amazon. (I've just done something similar on my Landy to wire in a DRL bumper but without actually cutting any of the wiring loom but using plug in piggy back wires where needed)

Ah thank you. That is really helpful.

I think your suggestion with some new connectors and run a new wire across is a great idea and the option I’m going to go with.

Try getting the light clusters from a breaker, it could be available with the plug. I will try to find the connector model later on.

There's this drawing:

But no details on the type. Or at least I cannot find anything

But a reverse image search gave me this:

282080-1 TE Connectivity - Connector: wire-wire | plug; female; Superseal 1.5; 24VDC; PIN: 2; AMP-0-0282080-1 | TME - Electronic components United Kingdom

TE Connectivity 282080-1 | Connector: wire-wire; plug; female; Superseal 1.5; 24VDC; PIN: 2 - This product is available in Transfer Multisort Elektronik. Check out our wide range of products.

It is called Superseal 1.5, 2 pin female, the manufacturer part number of this one seems to be the 282080-1.

And the male one seems to be this one:

282104-1 TE Connectivity - Connector: wire-wire | plug; male; Superseal 1.5; 24VDC; PIN: 2; IP67; AMP-0-0282104-1 | TME - Electronic components United Kingdom

The site lists the dimensions of the connector, so you should be able to confirm if it is the correct one.

Thanks for these links and all of your help.

Thank you, that is helpful. I’m going to play around with MES and just see if it is possible to change before I cut any wires

Hey guys, just thinking laterally - why not use a tow bar wiring kit? I have fitted one to my 4x4 and my recollection is its a plug in loom. There is a solenoid pack so I'm not sure if that will interfere with what you are trying? I personally would shy away from butchery!!

Ah ha - but actually, to fit the tow bar kit involves some butchery, as you have to physically cut into the rear fog wiring inside the boot (so the car's rear fog is turned off if you have a trailer behind you). Generally it won't help in this situation as really all the kit does is duplicate connections to the rest of the rear lights to the trailer plug, and allow for teh added current drain not having any side effects in the CanBus system.

I personally love this idea the most, as it will be an easy roll-back if needed. Then, the fog light cable lenght (=resistance) won't change, so it won't be problematic for CAN.

That's why I've searched for the connector (and I hope found the correct one, but someone having a Panda has to mesure to be 100% sure).

Cutting wires and adding good quality connectors is not an issue for me, but again, the a.m. idea is the best

 

[euroben]

Yes, I think this is the best option. I’m going to order some LHD rear lights and then I will be sure of the connectors and I can make up the extension ahead of time.

I can't disagree since my memory is such that I don't (fully remember)! I'm pretty sure though that the Westfallia kit didn't require any surgical intervention! I suspect that the fog light functionality is managed by the relay pack?

Anyway getting the correct connector seems a sensible way forward - if you can get male and female then even better!

 

[Herts Hillhopper]

This will help:
Photo of the connector on my Panda, and if the box of plugs and sockets (plus pins and seals needed), and the crimp tool, all ordered via Amazon. They are indeed SupaSeal 1.5 connectors. Link to search: https://www.amazon.co.uk/s?k=superseal+1.5

Better still, a pre-made cable with the right plug/socket combo! Buy two and then you can just swap the lights without moving any Fiat wiring at all…
