Wire pass thru - engine to interior
Seeking to run some wires for a laser jammer and wanted to know if anyone had found a good path between engine compartment and interior (i.e. firewall).

I'm not familiar with that specific engine compartment, but You should be able to follow the lead from the battery to the fusebox and through the firewall. They are usually a rubber gromet and you can usually slip an extra wire through no problem.

I ran my wires through passenger side firewall. You can't miss it. There is a much of wires that go through there and then I tapped into the fuse box on the passenger side footwell which worked out really well!

There is a grommet on the firewall where a clutch slave cyl/hyd line would be if it had a clutch. Just lift the insulation/padding above where you would normally find the clutch pedal and you'll see the grommet, it's pops out fairly easy. That's where I mounted the wires for my boost gauge and it worked out great for me.
