So im still gathering all the bits for the wire loom.
There is some $$ in the photo below.
I seem to spend a huge amount of time working out adapters to get it all to fit.
For those that want to know here is the result of my findings and make life easier.
The CA18 has two water temp sensors one for the ECU and the other for the dash.
The dash one (single wire) has tha thread of M12x1.25. The ECU one is the standard M12x1.5.
The oil pressure switch is a 1/8 BSP thread.
The oil cooler has a thread on the side (faces the starter motor and is only on the model with with water/oil cooler thing) this thread is 3/8 BSP.
My wire loom will be manufactured from 20AWG (Sensor wire) and 16 AWG (higher current draw wire) and the wire will meet M22759/32 or Spec55 made by Raychem and for the major part covered with DR-25 heatshrink.
I managed to obtain some second hand AF8 crimps and have two turrets for them, these turrets will do all my barrel pins and also Deutsch connectors. I still need to purchase a couple of crimp tools for the motec (AMP) pins and delphi metri pack. Haltech sell a set that includes some pin remove tools too, that look pretty good for the price.
In the pic below you can see the wheel speed sensors, steering angle sensor kit, pressure and temp sensors, coil packs and some of the tools required.
