TPS wire question...

[Dust Devil]

The three wires on the TPS...

Yellow/white...is the (0-5v Signal wire) that f.i controller tap into...

what about the other two, light blue and BR/BLK are either the..

sensor ground.
Or
0-5v reference/constant

I need to know which is the (sensor ground) to hook up my dynojet WB-2 O2 sensor for analog reading...

I know by using a DC volt meter with the key on...
One will measure zero...
one will measure a constant 5v to frame ground...

I'm asking if someone already "Knows" before i get out my meter...

And I don't want to (Oops) and short-out my ECU trying to meter the connection...

I already talked to Dynojet they confirmed the Y/W wire being the 0-5v signal Yet didn't know about the other two??

And I e-mailed Dynatek and asked them this same question!!

Yellow/white stripe= Signal 0-5v

solid light blue= reference 0-5v

brown/black stripe= sensor ground
