i have a 98 camaro with a 10lbs bottle mounted on rear hump and i was wondering if someone could tell me where to run the main line. undercar? or through firewall? and where would there be a whole already drilled for the line?????can someone help??

 

passenger side go up under the dash. you'll have to remove the door sill plastic. under hood, remove the PCM and you'll see the rubber grommet where the wiring goes through the firewall. i used a coat hanger to pull through.

 

cool thanks...

 

Did the same. I didn't even pull the PCM out. If you shine a light in there you can see the grommet and just slide a hangar in and pull the line out

 

you can poke it through the grommet and feed it through a couple inches, then find a skinny person to stick their bony arm down there next to the PCM and pull it out the rest of the way...i was able to leave my PCM in and get my bony arm down there

 

ya im not skinny and sticking my arm down there was not an option but did pull pcm and the install went smoth and looks really clean i will post pics of install at the end probably a couple of weeks.....
