Oil pressure wire mystery (1 Viewer)

[michaelharrisco]

my oil pressure quit working so I started to look around. I found this wire dangling, but I'm not sure where the other end is supposed to connect to. Looked around, but nothing obvious. Anyone know?

where does the other end of the wire go? to the gauge or to the block or frame as a ground wire?

According to the woytovich google doc list, is that WB for a "canister vent solenoid" A schematic coolerman has shows the oil pressure wire as YB.

Coolerman is storing a harness photo here: http://www.globalsoftware-inc.com/coolerman/fj40/schematics/FJ40/1978FJ40/WireHarness12_78_lrg.jpg

Here's the breakdown of the connections: December 1978 FJ40 Wiring harness reference

That wire appears to originate from the starter, but it doesn't look like an OEM connector and the color probably doesn't match the schematic either...

Where does it really originate?

The oil pressure sender is under the oil filter mount... If the sender doesn't have a wire to it already, see if that one will slide onto the sender.

I used a connector like that to replace the original when it wore out.

I think that is it. I forgot it connected right under the oil filter. I'll connect it all back tomorrow.
