Thread: Honda Prelude 97 Amp Power Wire problem

There is definitely a hole somewhere in that firewall, but you can easily enough drill a new one. Drill a hole someone w/ easy access and clearance form potential hazards of driling. Use a rubber grommet that fits the hole nicely and fits tightly the wire you are running. Run the wire from the battery and into an inline fuse, then run the wire from the fuse through the hole into the car. As far as more on this process goes there are probably a million pages on the net and probably tons w/ pics. Other than that, find a hole already there with a large water tight grommet and put a small slit in it just to the side of the existing wire, just big enough to carefully pull the wire you are running though. Make sure the seal stays tight.
