anyone fitted APEXi mechanical EL boost gauge on their EVO before?! no problem with the 2 wires ie. ground and amp; parking light, but the 2m rubber hose could be too short if i want to loop it out to the firewall via the ECU harness tunnel. is there a readily exit point below the drive compartment, seems to be a shorter path this way. pls don't tell me to drill a hole on the firewall coz' i rather not. next question: where does this hose fits/taps to?! the T-junction and filter comes together... any DIY photos or website to refer to?!
