87 Regular cab pickup trying to get a cable through the firewall and can't find anything obvious. Just need 1 cable for an amplifier and I'm doing this for a friend of mine. Any place existing or does a new hole need to be cut?

 

Opening in inner fender next to fuse block, bundle runs along inside of wheel-well, to opening into cab above or around the ECU. Similar on driver side.
Access by removing wheel-well shroud. 10-mm sockets, of course
Have electrical tape handy to re-tape the grommet/seal.

We've talked about this linking your Google profile images not showing up for those of us who refuse to log into Google sites 😜

Op is presumptively trying to run a power wire for a high current amp. Cut an X in a rubber grommet, like the engine harness seal, run your wire through it zip tie it on the inside and out side of the grommet, then flood the X with silicone or liquid tape..

 

i log in to google, and i can't see the image. just a big "minus" sign surrounded by a circle.

 

Thanks for the help. Once I removed the inner fender the path was super obvious.
