Where do you run a power wire either 4ga. or 8ga. through the firewall to the battery??? Everything seems sealed up. I did a search and didn't find anything....help...

[potroast]

do you have an auto tranny? If so then use a hole-saw and cut through where the clutch would go through the firewall.

I have done it on several 850's. here's a pic of a 4awg:

before you start cutting holes, look for a black hose type thing under you steering wheel and dash. It will have a cap on then end of it with 4 little black nubs sticking off. pull the black cap off and it's and empty tube you can run wires through without cutting holes. I found it in my car and it fits a 4ga wire perfectly. If you cant find it insde the car, look under the hood on the top right side be the driver side strut tower. sorry if this post made no sense

oh jesus no.. thats not necessary at all..

there's a firewall passthrough on the drivers side, its a little rubber nipple thingy, theirs like 4 nipples attached to one big rubber line, u just cut a nipple, feed the line through the firewall and then on the other side unerneath the drivers side you cut the coinciding nipple and feed it through.

volvospeed has a write up.. ummm link is HERE

this writeup is for a boostgauge but it shows you where the firewall passthru is.

OK, I'll to find that tube with the cap on it.....

it's definitely a lot easier than cutting a hole in your firewall. take the panel below the steering wheel off (the one, right above your knees when you drive). the interier nipple is behind a bundle of wires under the drivers side dash. I would take that nipple off, because when I ran my amp wire through there, it got stuck about 2 inches from the end and I tried and retried, putting it through, finally I just reached in with some plyers and pulled it out. there used to be an awesome tutorial on project850.com, I don't know why the site doesn't work anymore. otherwise I'd send you to that. I'm not sure who ran that site or whatever, but if they're reading, please put it back up, it was so helpful.

look under the master brake fluid chamber...wait, u have 96? hmm..i think it's just big open space there...at least, the chamber is there but the abs control module isn't. anyway...look in the area right before the windshield around where the steering column would be. there should be a rubber grommet there.



it should look something like this.



it's 8-gauge...but i've since changed it to 4-gauge...u just gotta make the hole in the rubber grommet larger

My 4Ga cable goes inside the ECU box and then inside the car.
