I purchased a pair of fog lights for my 2007 FIT (base model) from Walmart. Then I followed the instruction to hook up the harness, relay and switch. Now, the challenge is I don't how to connect the on/off switch between the engine compartment and my driver seat....
Can someone tells me is there any "hole" on the firewall????
PLEASE

 

i have this extremely high-tech apparatus that i use to feed
wires through grommets in the firewall...

metal coat hanger. LOL hahaha.

 

You need to snake it through just as you would with any wire in a house or car. The wires go through the firewall by the fuse box.

 

What i did is i used the main fusebox grommet behind the brake resivoir. It's easier to gain access from undernath the dashboard. I didn't poke a hole, i just slid off the grommet on one side of the edges and pushed the wire through, then i put the grommet back on as best as i could. it only leaves about 1mm gap. I have washed the car and engine bay many times and water has never gotten in because that particular grommet is pushed up soo far into the corner of the engine bay, water doesnt reach that area.

 

I don't know where is the main fuseobx grommet??Would you like to post a photo for me?!
PLEASE
