Installation of Cusco Oil catch can

[DNYALL]

My car is a 96 EK1 Civic d16y4.I have the Cusco catch can also.I drilled 2 holes in the firewall then mounted the Catch can.Bought some hose.It runs from yellow to yellow and green to green.Where the hose goes through the Intake Manifold it connects onto the PCV valve.
The stock set up has the hose connected from the PCV to the IM,so you have to get ya hand down under the IM and puul the old hose off and connect the new hose,then run that to the Catch can.The other hose from the Catch can to the IM:


We gots da same engine me and U Frankie! give me a PM anytime,about anything

Might be a dumb question but how did u go about drilling the firewall. did u take your dash off to check if there was anything behind where you drilled and to get the bolts in. or did u just use self tapping screws and screw into the firewall.

I need to re-mount my oil catch can (used to be mounted to the battery tray but now my battery is in the boot so want to get rid of the tray as well) but can't be bothered taking my dash off to look behind the firewall. and am too worried to just screw into it, incase i hit a wire or something...
