Hi everyone, I'm fairly new to these boards. Just got my 240SX coupe and have really enjoyed working on it so far. Since I've had it, I have noticed this one lone green wire that has been running from the battery, snaked along the firewall and escaping into a little hole in the firewall and ended up behind the brake pedal with a really crummy rig job. After the wire comes through the firewall, it comes down and it is butt connected with another wire that has a fuse and then continues to a little box behind the break pedal. I can't for the life of me figure out what it is. The hole that is in the firewall seems like there should be something there that is missing. I'm fairly new to these cars and not the best mechanic in the world so please take it easy on me. Thanks everyone.
Here you can see where it leads into the hole. Did something originally go there where the hole is?
Closer look.....
Further look back.....
In the car now.....shot is of the butt connector, fuse and block that comes behind the break pedal.
