Headlight Module Whereabouts
I was having issues with the headlights not coming on as they are supposed to. I bought a headlight module off a forum member (last year actually) but never put it in. I always got the lights to come on eventually.
Now, I’d like to install it but I honestly can’t find where it is mounted.
Sounds dumb, I know. But I feel smarter sending this message off to the vast Forum knowledge base instead of crawling all over the ‘vette. (again).
Any help is appreciated.
Thanks in advance.

The control module is located under the right headlight assembly..mounted to the bulkhead.

Now I don't feel so dumb for not finding it.......
To answer one of the questions above..
The problem I am having is that the lights don’t come on when I want them to, only when it gets dark enough. For instance, if I turn the lights on at dusk, while driving, when the instrument panel is difficult to see, nothing happens until it gets dark enough for the light sensor says it too dark. Then they pop up, and they do go back down after I shut the car down. When I got an inspection sticker, I couldn’t turn the lights on without releasing the E-brake. I know that’s connected to the circuitry, but I should still be able to turn the lights on at will, correct?

Your description tells me that your headlight control module is functioning normally, so there is no need to change it. The twilight sentinel is tied in with the e-brake, so the lights will not come on automatically with the e-brake engaged. You most likely have an issue with the MFS. Do a search, there are many threads on troubleshooting, and repair v/s replacement.
