did a search and only thread i could find pertaining to this was back in 2002. i've got the dual a pillar guage thingy and boost and fuel pressure. where is a good spot to cut through the firewall to run the lines of these guages. also where would be a good spot to tap the fuel pressure guage (electric, not mechanical) so it can get power?

thanks!

When you take the pillar off you can see striaght thru the floor board on the drivers side. I just fished the wires thru there with a hanger. Then just drill a hole thru your pillar. The dimmer light wire is located right by the fog light switch. Its the yellow wire which goes to the white wire + and the black goes to Ground -. The red goes to the key and the black goes to ground. I drilled a hole thru the firewall on the left upper hand side of the brake pedal. The hole will end up right behind the brake booster. I went ahead and cut the wires due to the the fuel sending unit plug hole would have to be huge.

I drilled a 7/8" hole through the firewall above the brake pedal like him.

Your fuel pressure sending unit will go onto the end of the driver side fuel rail. There is a schrader valve inside the rail that needs to be removed. You will need an adapter to attach the sending unit. Do a search for it in the Fuel section and you will find the part number.
