Extra Connector After Clutch Install

So, heres a little background.

I'm mainly a diesel tech and hardly ever work on anything that weighs less than a small house, but decided to help a buddy out and replace the clutch, rack, and brakes in his 1996 Tacoma. (V6 - 4x4)

Everything went pretty smooth, but for the life of me I can't figure out where this last small connector plugs into.

I'm assuming its the 4wd Light indicator, but it doesnt seem long enough to get to the t-case and only has 2-pins if I remember correctly. Its not the Rev. Light Switch or a plug to an O2 sensor...

Its a 2-pin (maybe... I do know its blue though...) connector - Its late and I'll have to wait till Monday to snap a picture.

I know its not alot to go off of, but you guys seem to have these things pretty well figured out.

Thanks,
William
