In fact the only spare plug I could find is a mysterious little red plug which is arrowed in the first pic & the arrow in the following pic shows where it was hidden.


Also thought I'd check behind the headlamp adjuster/diagnostic port as the on/off switch for the cruise control is located here so thought I may find a spare wire for that. Nothing again.

So, with the cruise control seeming like a bit of a dead end, I thought I'd briefly look into a possible cause of my non-working door lights - the BSI. A couple of people suggested that I may be missing a fuse from it. Well here it is with a full row of 6 working fuses:

Also thought I'd try popping a fuse into the several empty slots on the fuse box to see if they suddenly kicked in. As you can see there are a few empty slots - some with the metal contacts in & some were just empty holes:

Again, nothing. So after a couple of hours of faffing about whilst waiting for coats of paint to dry I've found nothing but a mysterious red plug hidden behind my steering column, still have no door lights & come to the conclusion that my car is actually wired for f**k all.
This is also the day after my funky stripe arrived, got fitted, then promptly unpeeled at the bottom of the curvy chrome strips. Admittedly though, this could be a combination of low quality vinyl sticky strip & an unqualified sticky strip fitter.
She's not doing a very good job of convincing me to keep her...
