Okay here is the deal, ive been working on changing my head gasket on my firebird, well i planned installing a gauge pod cause my car lacks actual water and oil pressure gauges while im under the hood.

Ive ran into a the problem were to feed the copper coil and plastic tubing from my gauges to my block, do i need to drill a hole in the firewall or is there a factory made opening i cant slip them through any tips or advice would be some help. Thank you

 

If you look under your dashboard and pull off the trim, you should be able to see your firewall. There should be holes in it with grommets to allow wiring to go from the passenger area to the engine bay. You could proudly just use the existing holes to slip the wiring through
