Oil Pressure and Temperature Senders

Oil Pressure and Temperature Senders
I am trying to figure out the best way to monitor oil pressure and temperature on my new engine. For cooling I am replacing the OEM oil warmer/cooler with a Mishimoto thermostatic oil cooler. The sandwich plate has 1/8NPT ports on it (just one from the looks of it) to put in a sensor, so I figure the temperature sender can go in there and I can use the OEM pressure sender location and a stainless steel 1/8BSPT to 1/8NPT adapter to use this pressure sender.
I want to use this CANchecked cluster gauge, which has 4 analog 0-5V inputs. Since it takes the place of the OEM oil pressure gauge I figure I can hook up the pressure sender to it, along with the temperature sender and possibly a solution to read boost, although I am almost certain I can use the MAP onboard the ECU to display boost through the CAN interface. I am using an MS3 Mini so I only have one analog input, this to me is a great way to add more inputs and keep the amount of gauges down inside the car since I am not fond of a bunch of gauges and pods and what not.

Temperature sender: https://bofiracing.co.uk/product/rac...sensor-18-npt/
Pressure sender: https://bofiracing.co.uk/product/hon...psi-5v-18-npt/
I want to make sure this solution will work and if there are any roadblocks I am not aware of. This is the first time I am using something besides the OEM dummy gauge so any advice is appreciated.
Edit: For more info on my build this is my work in progress spreadsheet: https://docs.google.com/spreadsheets...it?usp=sharing

I have a CANChecked gauge in my MX-5 (based in the UK) and have it connect to my MS3 (Rev supplied) - You can send Boost to the gauge via CAN, so that takes care of that one. I had the German suppliers add a setting for me to display boost in psi, so if you do purchase, make sure they send you the latest firmware. I also had them add miles as a speed setting option too, as it was kph only initially.
I haven't used the gauge's own inputs myself as i have everything into my MS3 - but the pressure sensor should work. Let me know if you want me to check any setting in my gauge.
Edit: Oh, obviously the temp sensor (being resistance rather than voltage based) will need to use the spare MS input, with the pressure going into an input on the CANChecked gauge.

I did some more reading through Trackspeed's MS3 Basic installation guide, and with the MS3 Mini after I delete the MAF (by using the IAT on my 01-05 harness for speed density) I have a spare 0-5V input through the OEM loom. That being said, I can instead use a GM CLT/IAT closed element sensor wired into the MAF harness and use it as an oil temperature sensor with the standard 3-point curve in Tuner Studio, or wire it directly to the inputs on the gauge, instead of figuring out what to do with the resistance based oil temp sensor I linked previously.
As you said oil pressure, boost (and hopefully AFR as I am using a Spartan2 wideband controller) will all work through the CAN interface and/or the inputs on the gauge.
Thanks for the feedback, please let me know if you see anything else wrong with what I said.

So how did you end up connecting the oil pressure. It has one wire on the pressure sender. I have a canchecked gauge and an aftermarket ecu with spare I/O, is it just as simple as hooking up the output of the pressure sender to the i/o port?
And if you've wired it into the gauge, how did that go?

Prior to making my own my sensor+GPS+WB02+Gyro+Fuel box, I did the following on my MSM:
I used the "now spare" MAF input (AIN1) for Oil pressure:
FYI: Electrical tape now replaced with a few gobs of craft glue.
The green-highlighted comments in the Notes column are mine and correspond to my sensor box configuration.
I made a small sensor box with a circuit board that has copper traces underneath running vertically connected to each hole:
The two resistors are for the Oil Temperature sensor, 2K49 ohms serial in total.
The "+/-" inputs are the 5V and GND from the MS3 connector above.
The "H/L" are the CAN High and Low from the connector above.
The "AT/OT/OP" are the Air Temperature, Oil Temperature and Oil Pressure signals to the MS3 connector above (all share the MS3's GND and the Oil Pressure uses the MS3 5V).
Mike van Esch: That oil pressure sensor has 3 pins, 5V, GND, and Signal (to the MS3)
