TPS wiring

[Slybeanx]

I am splicing wires to us a E36 TPS for MS on my M20. I have a 5v connection, but not WOT/ Variable. Brown Blue is dead. What would be the cause/ fix for this? Its the only thing stopping me from running rn and id like to get it fixed asap.

Are you wired up like this?

E36 TPS, pin 1 is ground, 2 is signal, and 3 is vref
E30 TPS, pin 1 is closed, 2 is ground, and 3 is open
Swap pins 1 & 2 on the E30 connector

E36 Stock wiring/TPS
1 = BRN(43) - Gnd
2 = BR/SW(12) - sig
3 = RT/GE(59) - vref

E30 Stock wiring/TPS
1 = BR/BU(52) - Closed
2 = BR(-) - Gnd
3 = BR/BK(53) - WOT

Running M5x TPS on E30 harness
1 = BR Gnd - Gnd
2 = BR/BU(52) - Sig
3 = BR/BK(53) - vRef

I spliced the brown and blue with the brown wire, here’s a pic of how it looks now that I’ve had to test them. The TPS is fine and tested w a voltmeter.

Does the car need to be running etc? My closed throttle is 400-600 same as my WOT in tuner studios.

Pretty sure I snapped my TPS when installing. Replace with a used one and swapped my adapter around and it works 100% now.
