"Brake Lamp" wiring location?

[demerson]

A few months back my 03 Pilot suffered a major rear-end collision while parked that obliterated the tailgate, and rear-left quarter panel. A local body shop did a relatively great job restoring my car to it's original condition, however over time I started getting creaking noises coming from the back end when cornering. Yesterday I took it back to have them fix the noises. Today I picked up the Pilot, and the tech informed me that majority of the noises were coming from the rear cross-member and they had to tighten it down near the 'rubber gromets on each side'. Since driving the car the noises are gone, but a handful of times I noticed the 'Brake Lamp' indicator would flicker for a second or two then go out.

So I have two questions...

1) I'd prefer not to have to take the car back, so where does the brake lamp, and brake sensor wiring run, that could have gotten pinched or losened when they tightened this stuff down. Pics would be l33t.

2) Could anyone post a pic of where the bolts (or whatever) are on the rear cross-member that he could have been describing so if I start hearing the noises again I might try and tighten those points myself.

Thanks for any help in advance!
