Im puttin in my new Genos garage Fuel pressure gauge. I cant see where i can feed the wires through the firewall. Do i have to drill my own hole, or is there a common plug or something i can pull out and feed the wires through? Im installing the gauge in the dash just below the air bag on/off switch.

 

There is a rubber grommet that is right above or close to the steering shaft.

 

Whats the best way to route from there over to the place im putting it. When i look through the hole, its all heater stuff. Also, where is people pulling power from? for the gauge?

 

Go thru the big grommet on the drivers side just below the cowl, to the right of the brake booster. You can cut a slit in it and run your wires thru it and up and into the a-pillar. Route the egt wires up along the spray skirt along the cowl. Mine started to fall off so I drilled five small holes and zip tied it in place, you can use the zip ties as loops to hold your wiring up out of the way.

Since your auto you can use the grommet that would be used to run the clutch lines through.

 

Yeah, that's where mine go.
