I've tried to search for this with no luck. I'm sorry if it's been covered already somewhere. I have an 06 custom. I've stripped it down to just a headlight and taillight. No blinkers no speedo no controls on the handlebars except the throttle clutch and brake lever. I want to mount a low oil pressure light somewhere on the bike for peace of mind. Anyone know about the wiring for this? Thanks in advance

Not a wrench but I think that switch is just a make or break circuit type thing. In other words, if you run hot to one terminal, the second terminal will be where you pick up the hot for the bulb.

Almost....

The hot goes to the bulb directly.
The oil pressure switch grounds that circuit when there is low oil pressure.

As oil pressure is increased, the switch inside the oil pressure switch opens the circuit, removes the ground, causing the light to go out.

If you take a multimeter to the terminal on the oil pressure switch and measure resistance to a ground point, you should measure zero ohms when the engine is not running. Remove motorcycle wiring from the oil pressure switch when you do this to prevent false readings.

There's only one wire coming from that switch...I guess I'll have to follow it. I'll mess with it another day

Right. That would be the ground wire for your oil light.


Remove that wire temporarily and measure resistance from the post on the oil pressure switch and a ground point. Should be close to zero with the engine off.

Oh I understand now. So if I wire a hot wire to a light and ground it to the pressure switch wire it should work. Thanks
