Vacuum line and wiring for 5th injector

[kevtar658]

Where did most people run this through the firewall? Did you drill a new hole or is there an exisiting one that works well?

Thanks,

Look at the pic on page 57 in the instructions. http://www.fastforwardsuperchargers.com/Install/Coldside-Install-99-00-PC-Pro-CARB-A.pdf

It goes through the big grommet for the main harness

I think the 94-97 guys run it through the firewall on the passenger side and then under the carpet to the PC-Pros.

There is a rubber plug installed in a hole in the firewall right behind the washer bottle. Not the big rubber plug with wiring harness, but another that is nearby. It is about 3/4 inch. You can punchure the center of the grommet and feed the boost line and fuel injector wires whought there. That should be all you need to pass through.

You will need to remove the glovebox, and cut a hole through the insulation to get to the wires from inside. Then run them along the transmission tunnel to the ECU.

I drilled a new hole right above where the accelerator comes through the firewall. The wires then ran easily up through the radio area and then under the plastic of the center console right to the ECU behind the seat.
