I just got my factory boost gauge and really want to install it, but i have no idea how to though, it has one vaccum line with a t fitiing on the end, and two electrical wires black and yellow. Detailed instructions would be great. How do i get threw the firewall?? Thanx
I'm not sure about the wires but you can get through the firewall by the pedals and then the line that goes into the bypass valve, cut that at about 4-6 inches off the bypass valve and put the T in for the Boost gauge. My guess is that the black is a ground and the yellow to some 12V or somethign for the light on the gauge. I'm not sure about the wires though. Just to let you know the factory boost gauge is known to be unaccurate.
