battery relocation question



Vince,
	I also have some 1/0 copper but it is only 13' long.  I will
have to run it inside and as direct as possible.  I plan on exiting
through the hole that the O2 odometer uses.
I just happened to see the set up from Accel and thought that I would
share it.
Rick K.

Wow! that's perfect and it's a good deal!

I ran 1/0 and it's a little big to handle. But there's a pretty clean
path
from the hatch up the drivers side into a grometted hole.  That stuff
looks
cool and is the perfect gauge for the job, and at $2.50 a foot its a
steal.
get it!

Vince
