I got under the '85 4+3 this evening to look for the oil cooler.
(Didn't find it.)

What I did find were two single pin connectors that are about 2" long. They were right by my oil filter and immediately fed into a wire bundle, so I could not track them.

Well, one was mostly unplugged. (In, but not clipped.)

What the heck are they for? I got no codes off the computer.

That's a for a 3/4 fexer valve. Use a little 30 weight and it should be fine.

Only thing I can think of is an O2 sensor wire or an ABS sensor wire (white or yelowish color). Anything unplugged off the battery cable + lead? I recall finding one similar when replacing a positive cable.

"They were right by my oil filter"

Methinks it was the water temp sender. Up until I connected it, I had a 'lo' reading on my dash. I thought it had something to do with my radiator cleaning tonite, but chances are that my mechanic properly burped it after the F&F.

Correct oil temp sender and the other could be for the 02 sensor or there is a 1 wire connector that goes to the temp sending unit between cyls.2 & 4 that connect down there. Pipe

I played around some.

The one closest to the oil filter is the oil temp sender. The one closer to the oil pan, tucked closer to the maifold is the coolant temp sender.

There we have it.

The oil filter attaches to the oil cooler and the cooler attaches to the block--the cooler is only 3 inches high and has a rubber hose/hard line from the main water pump hose and second rubber hose into the block.

I have an early '85 ironhead. I'm not thinking it has the cooler, but I'll check closer. I have not had the car very long and the last owner changed the oil for me when I bought it.
