I'm new to this great site and I need a few suggestions. I just started to add some aftermarket driving lights to my 2017 Fit LX. (I live in the mountains. Anything that lights up a critter at night is a bonus.)

What's the easiest way through the firewall? It looks like it might be on the passenger side. I see a thick harness (from the engine compartment side), but have no clue where that's going in the interior, behind the glove box. I don't want to blindly start drilling holes or tearing down the lower dash. It doesn't look like the driver's side is a practical path. It's too tight for a hand no less a drill. I'm missing something, somewhere.

I have the harness and a switch worked out. It's just the engine compartment to interior problem I have to sort out. Any suggestions. (This was so much easier before all these computers and wires...and when I was younger.)
