[s-cars] Autocheck after relaying headlights

[Sean Douglas]

Steve:

I know what you are saying, but the relay is a double-wide relay and
also controls the tailights and brake lights. If I simply removed the
relay and jumped everything, I would also disable the tail and brake
light functions.

The other way as you suggest is to take the relay apart and do the
jumping inside, however, I tried this and couldn't figure out all the
PCB tracings so I decided it was easier to do what I did.
