There are actually 2 connections - a SENSOR, and a SWITCH

The sensor has continuous variable resistance between pin 2 (middle pin) and Pins 1 & 3. The switch is On-Off between Pins 2 & 3 (it tells the ECU that throttle is shut).

SENSOR - Pin 1 connects to ECU Pin 48. Pin 2 connects to ECU Pin 38. Pin 3 connects to ECU Pin 30 (and to A/T control unit)

SWITCH - Pin 1 connects to ECU Pin 54. Pin 2 connects to ECU Pin 57. Pin 3 goes to A/T control unit.

ok in this picture i have it in red paint with red circle around it.... its a grey plug its 2 wires if i am correct it shouuld only have 2 pins and the third pin is empty?

but on my rb20 my tps on my plug it is not grey its a small black plug connector and it has 3 wires coming out of it, and 1 is a yellow wire that I can't seem to find a home for it, and if it helps my ecu is auto ecu so i was told the yellow wire i have is a auto kickdown b/s thing but i really dont know I just want it hooked up and wired right...

the problem is on my rb20, with the black connector plugged into my tps, the car will not rev and kinda idle's rough.... But if I unplugged it the high is sky high like 3 grand and still seem rough, but it will rev just fine without cutting off.

      Pillar gauges

      See, that button sounds like perfection Duncan! My eyes really don't like light shining at them from a dash when I'm driving. Being part red colourblind, I've found for most cars that I can change colours on, I set everything to red, so my eyes see the elast amount of colour! I miss normal gauges in cars

      bro, knowing the Japanese in  the 90's, i wouldn't be surprised if they shared components across their model lineup.

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Maaaan so many "little" things  i rly hope my old RB20 would be "ok" and not too bad. I try to learn what and what not do i need. I look at crossmember at it looks different...even parts numbers are different. Wiring and all that i rly do not know...yeah someone mentioned the speedo thing. On that yoke clip. I rly do not know what can and cant be done "custom" so that is why iam asking to know and not be suprised 🙂  I know what it looks like

      Oh, there's also the gearbox crossmember which will probably be different between the small box and the big box, and the wiring loom will probably need to be modified, because the plugs for the switches etc, will probably be different. And I think the speedo on the small box R34s is from somwhere stupid, like the diff, possibly, so you'd need to work out what needs to be done about that (assuming it is different). I think the thing you need to realise is that the front end of that yoke is a large hollow tube with splines on the inside that mates with the splines on the box's output shaft. It is a dedicated thing - not available "aftermarket". They were made to suit that box, by the car's OEM.
