Electrics: - Fitting foglights into a P1

ww1dm1 · Mar 17th, 2016, 15:41

I know there has been quite a few threads about this, but they left me confused now. I would like to fit OEM fog lights into my 1999 V40. Here's the information I gathered so far:

Wiring for the lights themselves is already there behind the hole covers;
Along with the lights I'll need a double fog light switch;
I'll need to replace the rear light relay with a double relay that's intended for both front and rear lights.

Here's where I'm confused - people say there should be an additional connector for the double relay ready behind the instrument panel but some complain that they can't find it - there is only one connector for the rear fog light relay. Should there be an additional connector ready? Will I need anything else? Is no ECU programming required for a P1?

To anyone stumbling by looking for information on replacing the relay, here's an amazing guide by bar72:

I don't know, do I? Do phase 1 models use a CEM? I thought they didn't.

So yours did have a CEM? What engine was it? Did you have to reprogram, solder, anything? Cmon, details man, details!

This thread has got like kids in the Kindergarten. If you show me yours I'll show you mine.

I have no idea what's going on here. I don't know if I have a CEM. I thought not, because I thought only P2 models have a CEM. I'd have to check. If I do have a CEM, is reprogramming necessary?

Alright, so I think there's no CEM on my V40. As I understand it should be in front of the blue immobilizer unit. Unless it's the big white box, what is that anyways?

The big white box IS the CEM.....
