90q No Brake Lights

[Tony Hoffman]

Well, looking at the schematics, it monitors everything, park, headlights,
and brake kights. On the V8, the brake light symbol says "BRAKE". I just did
it :) But, the switch being bad would indeed not trip the autocheck. The
autocheck is wired after the switch. It does indeed check resistance between
circuits. In fact, hooking up a trailer to the back of a V8 will trip it,
because of the lower resistance of the additional bulbs.

As for both bulbs being out, I'm going out to pull them both out of the V8,
I'll report back in a minute. I'm thinking it will still trip it.
