Getting multiple wires from engine bay to cab

I have been doing alot of mods to my truck here lately and i have noticed that i have alot of wires in the battery. I know i can install a terminal block but i will still have alot of wires going into one grummet (sp) . is there any other way i can get the wires inside?

 

I have a lot of wires too. As long as they fit and they don't strip, it really doesn't matter. You can always drill your own hole.

 

You should really try to keep the wire count down to just what is necessary. A single switch only requires a single wire if done properly. Try to keep most of it under the hood where there is way more room.

There is nothing that says you can't make a mess though. It's really unlimited how many holes you can put in the firewall.

Planning is the key. Planning will avoid a mess. Of all those wires you ran how many are actually used under the dash? Like in the Cab.

 

You could also poke a new small hole in another part of the rubber grommet and feed a wire through it. I've done this for the grommet under the driver's seat, just gently start a hole using an Xacto knife and start feeding the wire. Take care not to cut any existing wires and only make a small starter hole so that it stays tight around the wire keeping out the outside environment/dirt.
