You will need to tell more specifics about the vehicle - year, TDI, V8 etc.
I know one of the wires is for the coolant temp on the dash but what is the other one for?

it is a/c over temp cut-out, lars
don't swap the leads over![]()
Which temp plug?
Engine temp (gauge) front rh side of manifold...
Engine temp (EFI) LHS top of manifold...
thermo switch in thermostat housing...
Fuel temp )in fuel rail)...
Trans temp (if auto) in trans cooler line...
If you mean the one in the thermostat housing, its a thermo switch to switch the condenser fans on when things get hot, 103-105 deg from memory
The plug/ sender that is the most likely too be one that you wan`t to change will be the one in the most awkward sod of a position. Speaking from my own personal experience with a 3.9 V8.
