When looking up the pressure switch for 07 and up Im getting info that says the switch thread is 1/4" npt. As opposed to 2006 and earlier using the 10mm size.

Can anyone confirm ?
That is probably correct. I bought an adapter designed for the X100 to add an oil temp sensor, and it didn’t fit, so returned it. Here’s a photo I took back then.

X100 adapter and X150 sensor
The one on the right is definitely 1/4" npt. the other is M10.
I would have bet it was NPT, but nope it's not, It's BSPT which makes sense since its a British car.
My first clue was when I screwed a 1/4 npt fitting into the switch hole and it screwed all the way in. Not right, So did some digging snd the truth turned up.
So , here we go . 1st picture shows 2 connections in the oil filter cap. The one on the left Green is the oil pressure switch. The larger one Gray is the oil temp sensor.
Oil pressure switch is 1/4" BPST and the Oil Temp is 3/8" BSPT.
What I did was to obtain the right fittings from McMAster Carr and install a T setup for a 1/8" npt pressure transducer , using BSPT to NPT connector. Pic below.
Theres more than enough room to mount this large Sender and this is as far as Ive gotten. Now evaluating / searching for LED readout in rectangle format that dont cost $300.
Good info! When I was messing around with mine, some number of years ago, it didn’t seem like I had much wire on the OEM sensor to play with, yet you seem to have mounted the original sensor quite far from the original position.
Time and life got in the way of me pursuing it further then, hope to get back to it in the near future. Have the sensors, both temp and pressure, to hook up to my existing HKS Camp2, so your info will be a time saver!
