where does it go?

[3.0trd]

I have an 89 non-turbo 5 speed. bought it with a bhg in pieces. almost done getting it all back together and there is one connecter I cannot find a mate for... on the intake side there is a small loom of wires that goes down through the lower intake manifold with connectors that go to the starter, tranny and a few other things. I got them all into the right places except one. it is a white 4 pin connector with 3 wires. they are yellow, black, and red with a black tracer. I can't for the life of me figure out where it came off of! please help!
