They can come in all different technologies such as inductive photoelectric and capacitive just to list a few although the sensor technology may differ all 3 wire sensors are wired the same a three wire sensor has 3 wires present.
It came with every other wire just not the 3 wire plug wiring for the oil pressure sensor.
There is also a two wire oil pressure switch when it sees pressure it will complete a circuit.
To wire an oil pressure gauge make sure to get a copy of the wiring diagram for the specific brand and model of the device the manual usually comes with the purchase but the manual can also be downloaded from the manufacturer s website.
I had mine set up to use that however i buggered up the plug above the oil filter and now i need a 3 wire because i only have one hole now.
Here s a wiring diagram for the oil pressure sensor in your truck.
You can jump any of the three wires to keep the compressor in good condition.
I have a 87 s10 with a 99 5 7 vortec engine harness.
The voltage signal is sent to the pcm and then to the cluster to the oil pressure gauge.
We also have repair guides for your vehicle simply follow the previous link and enter your vehicle s info.
You can use that for a relay trigger or for an electric choke or any other thing you want.
The oil pressure sensor remember a pressure sensor varies a voltage signal based on a fluid or gas pressure.
The oil pressure sensor is from the 99 5 7 vortec the rest of the harness is finished.
Update spent awhile following the schematic and i had all the right power in all the right places but the gauge was not moving.
Three wire sensors are used in various applications from detecting parts to locating position of the actual machine.
According to expert maintenance tips it is essential to follow the previous readings in mind.
The oil pressure sensor is in the bottom right corner of the diagram.
Here are the instructions on how to wire an oil pressure gauge.
Anyways the 3 wires are orange tan and grey.
You can also browse excerpts by subcategory.
You should have 5 volts key on engine off.
Browse the excerpts below to find out how to access automotive repair guides through autozone rewards.
If i member right the oil pressure.
A switch is on or off like a oil level switch.
I need to know where the 3 wires go.
The oil pressure sensor is located on the top of the motor drivers side at the rear.
Key on check the voltage of the grey wire.
Fuck me running.
