I want to add oil temperature and pressure sensors to my 99 turbo running the above ECU. I understand from a brief conversation over PMs on another forum that I need a resistance type temperature sensor and a linear 0-5v pressure sensor.

​​​​​​I am however unsure as to how I would wire the two sensors once I have them fitted. The MS2 is configured with the temperature input as a 5v pullup so I assume I run the wire from the MS2 to the sensor, then the sensor to ground.

However the only 0-5v pressure sensors I can find have a 5v input and I'm struggling to work out where I would take 5v to feed the sensor with

There isn't a 5v reference for the TPS?

That hadn't occured to me, makes things nice and simple then

For the temp sensor buy the GM one from DIYAutotune. I will try to dig up some pressure sensor links on ebay for the ones I use. I use 5v from TPS for them.

I was looking at these for a pressure sender
Premium Oil pressure sender- Premium Fuel Pressure Sender

And a Bosch coolant temperature sensor (I'm in the UK so these are easier to source)

It saves a lot of hassle to use GM sensors for any NTC thermistors (resistive temp sensors) you add.

Here is the pressure sender I am using for oil pressure, and fuel pressure in my car.

Perfect.

i just need to pull the cover of the ECU tomorrow now run, pins are listed in the DB37 pinout but the colour coded wiring diagram Dimitris supplies doesn't list oil pressure/temp inputs

Should be pins 11 and 12 on the DB37 right? That's what I have for them in my ms2e docs.
