Unhappy unknown wire

i was changing the oil on my 1990 ranger 2.3 5spd to day. when i pulled my oil filter wrench off of the filter to take it out from the bottom a single wire with a connector fell down. the wire is red with a white mabye oragne stripe. the covering that it Ts off of continues on and conects to the back of the transmission with 2 wires. all my gauges work and the truck starts and has no error lights (however i didnt drive it long enough to see if the temp gauge worked) i felt all over the block and and looked all around the drivers side of the engine but coulndnt find a missing conection. is this just a extra wire? or somthing else?

Mmmm... it's probably not just an extra wire. Do these trucks have a low oil level sensor? That could be it, if they have one.

If you are feeling brave, ground it and see what light lights up on the dash.

How long is it? Stretch it out and see where all it'll reach to, it can't be really long.

The wiring diagrams for my 87 Ranger/95 Taurus/97 Explorer all show red/white stripe is the temp sender wire.

Probably the same on yours.

Your 1990 2.3 l. has a low oil level sensor in the oil pan. Look for it on the driver's side of the pan. If there is no wire connected to the sensor, that's where your stray wire belongs.
