A universal plastic molded firewall bulkhead type pass thru would be a nice addition to AAW's complete line up. I know there have been times that I would of liked to route a harness through the firewall but be able to plug it in on each side. So basically a universal bulkhead, possibly with different sizes to accomadate different harness sizes. Something simple similar to what comes with the kits like they use for the fuseblocks. With a foam or rubber gasket around it. Doesn't need to be billet or use any special tools. Just something clean and OEM looking.
