Wanna put gauges in overhead console and was trying to see which way would be better for gauge wires/switch wires to go down to firewall.

You have to go across the headliner and down the windshield pillar. I am not sure how many options that you figure you have?

Thank's Max Power, I already knew that. I want to know if it matters which way I would need to go when routing from overhead console down to the firewall. Drivers side or passenger side. It will be when I do it, boost/pyro lines and also the wires for the accessory switches. I've read it matters to go a certain way when routing for some reason.

I see. On my truck everything goes down the drivers side because my pyro probe is on the drivers side in the BD manifold. If you mount the pyro on the passenger side there might not be enough length to go in the drivers side so you might have to bring it in the passenger side and go up the passenger pillar. I have done this on a few trucks.

Other then that it makes no difference which pillar you go up. It's your choice, use whatever works best.

Is that BD manifold really worth getting,I've read about it before but not too much. If it doesn't make a difference in changing the manifold just to hook up the pyro I'll just tap the manifold. Does it matter which one (driver's or passenger side)I'd have to read off of to get a real accurate reading when I sometime do this.

I would go through the drivers side, if you want power to your gauges for lights then the fuse panel is right there and hook up to your light switch if you want lights to your gauges only when your lights are on! My 2 cents
