Ok this is a short post and after searching a few days I still haven't found a good answer. I'm looking to set up underglow on my Fc, however the only issue i'm having is finding a good spot for me to feed a wire from inside the engine bay to the interior of the car so I can mount a toggle switch for it. I would've preferred to have used a fuse tap on a fuse that only has power when the car's accessories are on, but there no "fuse" box under the hood aside from the one for the EGI and other stuff, but those fuses are different and I haven't found one that I can use an add a circuit kit on. I just need to be able to get a wire from the battery to the dash without cutting up my car.

 

Frank, is your main concern just physically getting the wire through the firewall? Both driver and passenger sides of the FC have huge rubber grommets where the emission and front body/engine harnesses pass through the firewall. It couldn't get any easier...on my 10ae the emissions harness had a nipple that you could literally snip and is a perfect and clean pass through the grommet.

There's also clever things you can do like using the existing AAS wiring if your car is not equipped.

 

Awesome thank you so much for the info, What is AAS? I have a base model so I likely do not have it. If it has to do with the suspension im on coilovers so I def wont.

 

AAS = auto adjustable suspension

 

ah thanks man
