Where is a good spot to run wires through the firewall for adding additional lights and power wires for other stuff? Have a 95 sport with 4.0. Please help!!

On my 98, there is a big wire grommet in the driver's floorboard above the pedals. I don't know if there is one there on a 95 but it's worth taking a look

My 90 has a hole behind the vac booster. Here you can see the marks from the cramp-onns the mice were using to climb. Actually I'm not sure what gear their teams use. (was thinking I could drop a little piano on them)

Any holes where there is a rubber grommet are good. You could also find a blank area and drill another small hole (watch where you drill!) and seal it up with another grommet or something of the sort. You can also get small diameter rubber hose and slit it longways down the middle and put that around the circumference of the hole to protect the wires from ripping on the sharp metal of the firewall. Keep any drilled holes as far up as possible so water doesn't enter and make sure you don't drill into anything important. Use existing holes as much as possible.
