I made a bit of a school boy error.
Engine wouldn't turn over in the car, so I took it out. After I'd gotten it out I had run out of time to do any more work on it, which is how I left the last post.
Next time I went I realised the engine wasn't seized at all, it turned over freely. Whilst it was out I used a boroscope thing with my phone and inspected inside the chambers, no damage or FOD. All good.
What had happened was that I'd used a bolt which was just too long to hold the slave cylinder to the bell housing

this was locking the flywheel and fooled me into thinking the engine was seized. Oh well, small set back in terms of pulling the engine out, but whilst it was out I did change the gearbox tail housing for a spare one, as the one I had, 1 of the 3 bolts holding the shifter in was broken off.
Before re installing the engine, I checked the end float on the crank, as I'd over torqued the front pulley nut. Sure enough, it was too tight, so I unded the pulley nut, and re torqued it to spec, then the end float was back within it's tolerance again.
Engine is back in now, and I'm back on to wiring. I'm about 70% done with wiring, the wipers have proved a bit challenging to keep the park function.
The dash is in, and the instruments all work. I am re using the original column stalks for light and wiper controls, so have been going through taking pictures whilst testing the pins on the back, to check which pin corresponds to which function.
I have ordered some yazaki connectors, I only have 1 useable connector.
I have filled the engine oil and turned it over on the starter, the oil pressure gauge, low oil level and low oil pressure warning lights all work, and the engine turns over fine and has plenty of oil pressure on the starter.
Once the wiring is finished, it's onto the exhaust, and should be starting it up soon.
