Momo,

I am also setting up a Switch Pro (SP9100,) and after looking throughout the whole toyota-4Runner.org looking on how people setup their SPs in a 4Runner 4th Generation, I came across your posting. And, I have a few questions regarding your setting.

1) What holes did you use to pass the controller and trigger wires thru the firewall?

2) How many trigger wires did you passed thru? I understand the ignition wire does not have to pass thru the firewall, at difference from the 5th Gen, ours has the ignition fuse in the engine compartment.

I love what you have done to your rig, I've been closely following your blog for inspirations. I just pulled the trigger on the SP9100, and I love the way you set it on the center console!

3) Would you be able to take a few snap shots of that section of the setting?

Looking forward for your response
