Hey guys the previous owner cut the plug out and i found the wires but im not sure how they should be wired up

A picture of the actual plug would help me out thanks

its a 91 N/a s5 thats been turbo'd but still uses stock harness+ecu if that makes a difference

thanks

 

This help?

 

oh im sorry i meant the plug on the shock tower to calibrate the tps the 3 plug one the wiring diagram doesn't help as it shows only 3 wires going to it when i have 6 wires here

 

o'rly

 

The TPS check connector is green and has but three wires. One wire is black/white which is the power wire for the LED's and the other two are the same color as the wires on the switching and relief solenoids.

On a series four car the TPS check connector is located near the right front strut tower. I suppose the series five is in the same location.

 

just curious if i dont have the solenoids in the car will the led's still light up?

 

Yeah. It's the ECU that outputs a gnd signal to the TPS connector and the two solenoids at th same time.

The L/Y wire at the TPS conenctor also goes to the relief solenoid and a gnd is put on that wire when the TPS outputs approx 1vdc. Again, the wire can be off the relief solenoid and the gnd will still be put on the green, three socket TPS check connector.

The other wire in the green, three socket TPS check connector is L/R and is spliced into the L/R wire on the switching solenoids elect plug. Plug does not have to be connected to the switching solenoid for the gnd signal to be put on the green three socket TPS check connector.

Neither the L/Y nor L/R wire should be touching gnd or eachother if those plugs were cut off the respective solenoids.

What's wrong? The LED lights are not coming on when plugged into the TPS check connector when you adjust the TPS? I think the key needs to be ON and engine Off when you do that.

 

Hey Dude, i just replaced my TPS two days ago on my FC3S turbo so here are some pics i also took some pictures of the older one as the wires on the new plug where slightly a different colour. I found some NA TPS pics aswell on the FC3S pro forum they mite come handy, i hope they dont mind.
