need to where to run your power wire in the fire wall or can't you? i need the factory wirng clolors for the main harness for the radio some one cut the plug out

 

I don't like squeezing power wire through the stoclk hole, especially if it is 4 guage or larger. I would suggest getting a grommet and drlling your own hole then run it into the cabin.

 

Not sure on Preludes, but on Civics and Accords, there's usually a grommet on the passenger side right below the glovebox area. But as previously mentioned, I'd just drill a hole and put a plastic grommet in. Just look twice, drill once.

 

either under your steering wheel column...a little above the pedals...or by the passenger side under the glove box..there should be a whole the size of a quarter almost...

 

Id say most likely the steering column, ive seen it done before...2 person job, one to push it through, the other to grab the cablr through the other side.
