1.8 TB/TPS for use with 1.6 wiring
I know that this is a fairly common subject of discussion, but I've not been able to find a simple statement on how to correctly wire a 4 wire 1.8 tps pigtail into a 1.6 wiring harness.
I have the pinout for a 1.8 TPS listed as:
Lt Green / Red = 5vref
Red/Blue = TPS Signal
Red = WOT Switch
Blk/ Blue = GND
Per Brain. And was told by Reverant that I should be able to ignore the 4th wire, in this case the WOT, and just pair up the other 3.
Can someone clue me in to the pinout of a 1.6 TPS plug so I can match the wiring? Or give me a rundown on which color wire should go to which? Or just let me know if I'm somehow missing something and this will not work how I intend it to?
Much appreciated.

I feel the need to chime in here, for my setup this was incorrect. It may be my MS harness was wired slightly backwards, but in any event I had to reverse the 5vRef and TPS signal (Green with white stripe and I think black/green) wires to get a good reading. What was weird was it did "Work" but would bounce all over the place and my calibration values were like 720-820 when it was wrong, but when I reversed the wires and made it correct these values were 100-800ish (Notice it's a much wider range and thus is less susceptible to noise).
Most important thing is your values in calibration look are about 100-7/800. Otherwise reverse it. As always solid red (tps sensor side) is unused.

I did find this which I think could be helpful for people going forward. (I've not tested it to see if it works yet though, hopefully I'm not propagating bullshit)

Lt Green / Red = 5vref
Red/Blue = TPS Signal
Red = WOT Switch
Blk/ Blue = GND
Lt Green / Red = 5vref
Red/Blue = TPS Signal
Red = WOT Switch
Blk/ Blue = GND
then you should connect:
RED to RED/BLUE
BLACK to BLK/BLUE
GREEN to Lt Green/Red
according to this:
so therefore id wire it like this:
what elfering suggest will never work.

I'm still having issues with this myself, after trying with that picture I had found. Its definitely not correct. I'll try with the suggestion that Braineack made today.
Unfortunately I'm using a TPS plug Snipped from a protege and the wire colors are different so there's a small amount of translation to be done.

Seem to have gotten this figured out but my tps gauge still wanders a good 5-10% when left alone. I'm guessing that's probably due to signal noise and I'll probably wrap my signal wire in tin foil or something to try to help it. (At least the solder joint portion).
For future generations sharing my struggle, using the pictures above and looking at the 1.8 tps plug with the press release facing upwards.
From left to right:
Pin 1 to Green and White 1.6 wire.
Pin 2 to Red 1.6 wire.
Pin 3 gets left out
Pin 4 to Black and Green 1.6 wire.

I made a much better diagram that's in my 1.6L MS3X and DIYPNP install docs:
OE = 90-93
the above is really confusing. "black lead on DVM" ???? for both the 5v and ground? Nice diagram, *******.

This is a different than how I have mine wired and what I had previously posted above, I'll have to check again but I believe I have pins 1 and 2 backwards from your new image. Mine seems to be reading correctly but the reading wanders after almost every drive by about 10% in one direction or another. I had always just blamed signal noise for this but I may flip some wires around and try it this way. Thanks for uploading this.

I feel like a bit of an ******* for not coming back and updating this, cus everything else I was reading didn't seem to make sense and other people seemed to be doing it differently, but THIS diagram Brain posted is exactly what I ended up figuring out. I have a question though, what happens if you wire it this way on a stock 1.6 ECU, you lose WOT but if your not running A/C or P/S does that really matter? Asking in case I ever 1.8 swap a car without doing a megasquirt first.
