Sooo, nearly there but not quite.
Spent most of the weekend doing the wiring. The Megajolt is now in and properly wired up, I've wired up the Sportpack dash and it does look great to be honest.
I've got the engine all sorted now, it's been turned over until the oil pressure light went out. I just haven't fired it up because I need to sort out a fuel pump relay before I can. It's definitely a proper mini though, it's got an oil leak! I'm a bit pee'd off with it really. It's coming from the O/S diff end cover, which means that I've got to drop the oil, pop the driveshaft out, and replace the gasket. Bit of a pain, but I'm going to wait until I drop the engine oil after the engine's been run in.
Man, I hate wiring. I followed the wiring diagram in the Haynes manual for the sportpack dash, but it's wrong!

the direction indicator wires are the wrong colours in there! Anyway, got around that and sorted it out now.
Anyway, it's very nearly ready to go. But I've got to go to Cornwall next week with work, so it's going to have to wait until then now.
Still got a LOT of bodywork to do on her, but that's all the good bit!
