wondering if anyone ahs the wiring diagram for an s5 ahndy. need to rewire the h20 thermosensor, is one a ground and the other a signal wire to 2E on the ECU? I havnt looked but is one wire black (the ground, if it is of course).


or does one wire get that 5 volts from the sensor power (vref, pin 2I)




well after reading what I wrote, you can disregard the above statements... im guessing ive got a brown and white wire (vref) that should read 5v, and then a sensor wire that runs back to the ecu? riiight? so if I know the sensor is working, and ive got 5v at the brown and white wire, that means that I should just re-run the sensor signal wire back to the ecu (pin 2E)

thanks team

 

well u can purchase the haynes manual at ur local car store.. but i think i seen some manuals on this forum. but if its not there then sryy.(at least i tired).......

One wire is to 2E, the other to ground. The original ground was a common ground used by all the sensors. A Brown/Black wire. The one to 2E is/was Green/White.

 

yeah so its a brown and BLACK wire? I know brown and white is the vref, so br/b is a ground? does it NEED to ground to the ECU grounds or is a chassis ground ok (ie, green white from 2E on ecu, to sensor, then brown/black on sensor to ground.)

 

A chassis or engine ground would work.

 

awesome. thanks man
