Wiring – front to rear routing

[lough90]

I’m planning to run some additional wires from the dash board to the rear pillars for additional speakers and power outlets. Before I start I was interested to know which is the best way to route wires from the front to the rear

Up the passenger side A pillar and though roof above front passenger and onwards to the rear. Easy access and plenty of space.

Agree with @HHO
Main wiring loom through roof runs on passenger side so that is probably your easiest route as you can tag onto the existing run
