2005 Mercruiser 3.0, Alpha Drive.
Just finished replacing the rocker cover gasket and removed the Water Temperature (audio) and Water Temperature Sending unit wires from front of thermostat housing, but failed to tag them. Without taking each out and breaking the seals etc., is there an easy way to visually identify the Audio unit from the temp sending unit? I have the wiring guide, but don't know which is which visually.
Also, there is a third wired brass unit plugged into the port side of t-stat housing - what is this for?
Please see image with questions.
Many thanks to the community!
