wire routeing

[vaderj]

Ok, So I am installing both a single 10 and also trying to figure out how to hook up my pcm tuner which requires both a usb cable and cat 11 cable (standard 4 conductor telephone).
Firstly, where is everyone penetrating through the firewall at for the amp power?
Secondly, Any clue of how to route a couple wires from the ECM location (under passenger side wiper) through firewall in possibly into the glove box?
only options I am seeing as of right now involve a drill and I really dont want to do anything permanent quite yet

thanks!

there was a rubber grommet under the drivers side of the dash, i just used that to run the power wire through the firewall

i just drilled through the firewall on mine. i used a firewall grommet and some silicone to seal it up after the wire was passed through. i think there might be some big rubber grommets behind the front seats on the floorboard. maybe someone else can chime in on this.

I am just wary of drilling through the firewall because up here in ND it gets a hair chilly ( a -60 windchill is common a few times a winter) so I would like to keep the cab as hole-free as possible!
The grommet and silicon crossed my mind, I just dont like the idea of silicone'ing in the cables to my $500 tuner either ....
by the way today was a blistering hot day .... we broke freezing!

The hole you'll make aint that big.

The best place to drill a hole is just above the wire pass thru, upper right corner. The picture is of an Explorer but the Ranger is similar. The fuse/relay block is held in place with 2 10mm bolts. I do it this way cause it much easier to drill from the engine comparment side

look at your petals some times the 5 speed and the auto are the same design, so you have a big empty rubber plug from were your clutch stuff should have went.

i ran mine on the passenger side. theres a rubber groumet on the floorboard on that side too. ive dun the drilling in the firewall on my 90 model n that worked too. Ranger SVO is right, the whole is hardly anything. n usually amp kits will come with special groumet at jus the right size for the power wire. but i understand what u mean Vaderj bout not wanting to drill. So run it throu the groumet on either the passenger or driverside floorboard. if u dont want to do the silicone thing then jus drill a hole in the rubber groumet jus big enough for power wire to run throu..
