Thanks for the comments lads. Both myself and my FiancĂ©e love the Mini too. Is definitely a fun car to drive around in! Wish I hadn't scrapped the 3 I had previously now (wasn't into the whole Mini thing then).. especially as one was an old K-plate that I paid £40 for although needed some welding, I found out when the accelerator pedal fell out of the bulkhead.. hah.
Here's the pictures as promised Lee. Click on the images for the (rather large) fullsize images (each ~1.5Mb).
Solenoid mounted in the bottom of the door

Bracket and hinge mechanism connecting the solenoid to the locking bar (the bottom has a rod with a hook that connects into a loop on the end of the solenoid)

Hinge from above showing the connection position by the small "S bend" in the locking bar

Wiring connectors between the loom and solenoid (will need a crimping tool to add the spade connectors to the ends of the wires)

What job would be complete without a bit of sparky tape? heh. I used this to try and keep the loom away from the window. It didn't catch when the window was wound down, but I wanted to make sure anyway

Holes drilled to take the loom. IIRC now, these require a 13mm hole


Hope these prove useful

Regards,
Ian
