i dont want to mess anything up on my little wagon so i was wandering if any of you have installed a stereo, or anything else through the firewall, and if so where would be the best place to enter in at? thank you. Devin.

 

The stereo already has a harness, most people just tap into those wires. If I had to go through the firewall, I would likely go through with the cruise or turbo vac lines.

 

no i know how to wire in all the speakers and power to the radio. Im installing a power wire for the amp. and i have to take it through the firewall, my car is n/a so i have no idea where the turbo vac lines would be ran, im not familiar with boosted Volvos lol.

Also, i was thinking about going in through by the throttle cable it just looked a little high up in the dash to go through there. I ran out of light to finish and i figured id ask before tearing anything up tomorrow lol.

 

What are your plans that require you to use a 0 gauge line?

 

I can't say this is the best place but I didn't hit anything on the other side. I removed the center console and ran the power and ground wire under it.
Works for me. I do need heavier wire but I plan to do that when I install a second battery.

 

The 850's have a flexi-tube with a rubber end on it in the engine bay. The rubber end has 4 little knobbly things on the end and has a matching one inside the car, run it in through that. That is where the cruise/turbo vacuum hoses would run if it had those options.

It should be between the brake booster and the side of the car, the rubber cap just pops off.

 

I need to run a hot wire from my engine bay to my tow hitch harness.

 

Good idea brick buck its all under a bunch of stuff and between the shock tower bump. Where does it dump off in the car about?

 

Well mine being right hand drive it may be different, but mine comes out next to my accelerator pedal.
