Sorry - no pics. I drilled a hole in the upper-left portion of the driver-side firewall and used a grommet. Sometimes you can find an existing grommet or plug you can pass thru a small diameter wire, so look around the desired proximity.

While investigate possible locations, pay close attention to any nearby moving parts, and/or HOT parts.
Use plenty of zip ties to prevent your wires from vibrating, and getting chafed, also.

Thankyou very much. I've been playing with using the hole where much of the wiring goes thru the firewall. It's located near the brake master cylinder. I have some plastic conduit to keep separated from other wires. I don't think I be able to get everything thru there so I'm looking for a 2nd site also.
