It'* a home made splice--seems to be(from memory)the orange wire spliced into a brown wire.
I'll have to double check on Sunday tho.

Uh-oh. Although you didn't say which is which, I'm willing to bet that your brown wire is the Bonneville wire; the orange wire is the aftermarket wire. See, brown is the car'* exterior lighting circuit (parking/side-markers/taillamps).

Are you looking at an end-to-end splice, like this?

==Brown==><==Orange==

That means that they've snipped your exterior lighting circuit coming out of your headlamp switch. Idiots.

You should, at minimum, be seeing this:

==Brown================>
^
|<===Orange=tapped=in===

The orange wire could be connected _to_ the brown wire, but it shouldn't have _severed_ the brown wire.

There is one possible explanation: they may actually be interrupting the circuit, diverting the lights _through_ the alarm box, with another connection coming out somewhere else that you haven't found yet, like this:

==Brown==><==Orange==[ALARM_BOX_HERE]==OtherColor==><==Brown==

...in which case the alarm box has screwed up and blocked all normal lighting current through it, or else its other connection, the outbound one going back to the brown circuit that you haven't found yet (if it exists), is broken.

Wiring diagnosis is _so_ much fun, isn't it? But hang in there because I really think you've almost figured this out.

I'm bringing this post back--lots of good info about those damn headlights!
My projects have gotten out of hand and I wasn't able to check on the brown/orange wire situation--yet, but I will this Monday.

Well, all the exterior lighting _except_ the headlights, but I know what you mean...
