ive seen a p38 fog light switch go for £40!!! i stopped bidding at £10.
as for fitting fogs you have to have a wiring loom, front fogs (doh), a relay, and someone with a rovacomlite, cos it has to be enabl;ed in the becm. until its enabled in the becm there is no way you will get the fogs to work, unless you hard wire them to the battery!
oh and the original Q in this post. That RR is deff 100% sure a 2.5DT, and someone has stuck on a SE badge.
