Electronics on the brink!

Has anyone ever had a problem where the 12V accessories (ie: cig lighter, most switches, clocks, stereo, etc...) just start going completely haywire? I just got done installing an intake manifold/throttle body on my 91 integra gs, and after adjusting the TPS, i started the car, and my electronics in the car went to hell. The first symptom was, i plugged in my radar detector to the cig lighter, and instead of the detector coming on, my door and trunk light illuminated. Then, all my switches on my dash started coming on and off. I also noticed the clock was flickering in and out. Anyone have a clue as to what is going on? I am completely lost. :confused:

double check all of your grounds...

i found it... it was a fuse for the interior accessories. i guess when it goes, crazy things happen in the car? its fixed now. thanks for the advice.
