im jus wondering where do u run your power cable to the back of the 08n xb? wheres the hole for the power cable on the firewall? help please!!

 

thru the big firewall grommet

 

thats through passenger side, what the best possible ground in the rear for the 08 xb's?

 

behind the rear seats under all the mats is where i put the ground for my subs just sanded the paint alil and drilled through

 

i wouldn't drill try to find the factory ground point back there

 

btw, do u know the part number for the wire connectors for the factory stereo to install a aftermarket deck? i jus bought one and its a schosche TA021, it shows that its for the scion xb from 04-07? its an 08 so idk....you know whats the correct number for the factory harness?

 

Any recommendations on how to get power directly from the battery and run all the way at the rear? Any entry point if I run it outside and go in underside? Or better to run through the firewall and back to the rear... ?

I'm wanting to run 10 gauge wire suitable for a 500watt inverter I'm putting in. Will be fused up at the battery.

Thanks

P.S. Where exactly are the 'factory ground points' under the rear seats?

 

i ran the wire thru the stok hole for the clutch cause its an auto matic, or youcould run it through the big rubber grommeton the right firewall, or since its a 10 guage u can run the wire thru the drivers fender thru the lil plastic guard then into the stock harness were the wires run thru from the door, then your in the cab already n run em all under the plastic moldings n your all good

 

the wire harness is the same for the 08 as the 07, I put my ground on the bolt in the back where the silver tie down hook is, It works well... as far as a power wire I would not run it on the outside of the vehicle..

 

i ran it through the one behind the glove box. mine was 4g but with a little force it went through
