power wire routing from engine bay
 

I was just wondering if anyone has a 2002 nissan sentra and who knows a place in the firewall to route the power wire? I can't find a place anywhere!

Prolly underneath the stearing wheel?

Usually it's easier to look from inside under the dash. Locate something with a grommet in the firewall that will accommodate your size wire . Then look to see where it is under the hood. Sometimes the brake booster hides good spots under it. Then there is always making your own hole with a metal hole saw & proper grommet. Don't forget to use a lil silicone after to keep out the water.

I have an 01 sentra, and I couldn't find one on the drivers side. I just drill a hole. A good location is just above your left foot on the drivers side.

use a step drill bit.. work like a charm just watch for wires in the engine bay

There is a very large grommet in the driver's side front tire well.
You can run the wire in the fender, nice and hidden away.
You'll have to pull the splash guard out of the way.
It is a bit of a pain, but it saves you from drilling.

I can take a pic if you want, my 03 SpecV is up and the plastic is out, well so is the motor lol.

I think that's the route I'm going to have to take with my 2002 Protege 5. Problem is I don't have the tools to efficiently route the wires through the wheel well. Could be an all day job.

Pics would be great if you have some!!
