02 WRX sedan

I did a search and found most of the answers I was looking for but there are a few things I'm still not sure about.

I already have an Omori EGT gauge and radar detector installed and they are tapped into the fuse box but I'm about to add a knock light and an Omori electric oil pressure gauge. Since Omori gauges can't be hooked up to the OE dimmer I'm thinking I want to tap the 2 Omori's into the clock with a rigged dimmer switch http://www.scoobymods.com/forums/showthread.php?t=3115 I would also like to run the knocklight and the radar detector to the clock bypassing the dimmer but I'm not sure if running all four to the same spot is going to overload the circuit. I think it should be OK but I just want to make sure.

I can run communication wire in a building as good as anyone but I don't have much experience when it comes to wiring in automobiles so sorry if this is a dumb question.

Please help, if I continue hooking this stuff up like I have in the past my fuse box will end up looking like a birds nest.

Thanks

 

I just noticed that the clock doesn't have a dimmer so I'm guessing I'll have to tap the Stereo harness. Anyone know if the 02 stereo harness is the same as the 04's?

I've put 100k on this car and just noticed the clock doesn't dim (bangs head on desk).
