That is gonna be a pain in the ass. There is a rubber grommet under the brake booster, in this general area.( but lower, beneath the brake booster) You can find it by following the large wire harness that goes through your firewall.



Or, if you go and buy a hose that is about 8ft long, you can go through your passenger side, where they ran your amps power line. I went through under my brake booster, and it is a bĂ*tch.
