help, where does this go ? (see pics)

[jonathan]

See the grey plug directly under the fusepanel in the above picture ?

I need to know what this plugs to. I ASSUME is goes to a solenoid or control box. If someone could look under their dash and look to where this plug leads to. I am pretty sure it should plug into some sort of standalone box and not another harness.

It does not go to any type of dash switch as I have eliminated all of those.

Hints: It has something to do with the headlights, probably the highbeams.

I checked schematics (aint that a ***** !) and it didn't really help.

The plug is a 4 slot female type, with 5 wires going in to it. 1 of the wires leads to the plug where the headlight bulb plugs into.

Running power to one of the connectors turns the highbeams on.

it has :

A this red wire w/ yellow stripe
thick red with black stripe

thinner green w/ black stripe

thinner lighter green w/ black stripe (this leads to lightbulb plug )

thinner blue w/ orange(peach?) stripe.

It does not plug into any other plug (I triple checked everything) and does not plug anywhere into the steering column.
