So I'm trying to figure out the sensor wiring for the oil pressure - see pic below.
There are four wires hanging there disconnected.
One Solid black 12 ga - goes to starter ground
One Black w/green tracer 14 ga - goes into wiring bundle
Two Tan w/red tracer - goes into wiring bundle
NOTE: Pay no attention to those connectors - I added them trying to figure it out. When I found them, the connectors were all broken.
You can see the two sensors there. I'm assuming that the one with two poles is the sending unit for the pressure, and the single pole is the alarm circuit.
I checked the back of the oil pressure gauge and the wires are black w/green tracer.
The second pic is from a VDO diagram on their website, I am assuming that my sensor is probably Illus. 2 - which would mean the floating ground to the starter goes to one pole and the black w/green tracer goes to the other.
However, I'm at a loss for the other two wires and what runs the alarm circuit. The alarm doesn't work by the way - when I turn on the key, there is no tone.
Does what I'm saying make sense? Anyone else lucky enough to have this setup with this color combination and can shed some light?
Thanks in advance.
