Default Gs300 electrical wiring diagram schematic

Hey guys. So I've been having some problems with my 99 gs300 lately. For the past 3 weeks now, my headlights would dim when braking and rolling down my windows. Notice the radio would cut off for a split second every so often too. I checked the battery connections and terminals. Had both the battery and alternator tested, both are in great working condition. Been told by a few friends that it is most likely a ground connection issue.

I know this topic has been covered over and over again throughout the years (google) the whole headlight dimming issue is starting bug me even more as time goes by, and I'm just ready to tackle the situation myself.

Don't have the time and option to leave my car at a friends house or mechanic shop for a few days, too busy with work and school.

Been looking for the entire electrical wiring diagram for a 2nd gen gs300. most of the links are out. was wondering if somebody has a diagram available, or know of any links without paying preferably.

Thanks in advance!
