Whilst labeling all the various plugs that fit into the UIM, I came across THIS one that I just don't think was ever used. It is a black plug with a yellow center. It has 3 female prongs on the tab with a flat side. It is part of the wiring harness that has the ground wire loop right on the rear of the UIM. Am I right in assuming it is just an unused plug?

I don't recall having any unused plugs in the 1/2 dozen times I've had the UIM off...

I think it goes to the O2 sensor but not sure. If not and you got block off plates then it probably ain't in use.

Are you sure it's not for the idle speed controller or air temp sensor, or one of those other sensors on the back of the UIM?
