I'm installing a boost gauge, Air/Fuel gauge and Electronic Oil Pressure gauge in my 03 Speed. I was able to find LinuxRacr's install guide on the Air/Fuel gauge and the boost gauge install elsewhere. However, no luck on the Oil Pressure gauge. I realize it will probably be the easiest one to do, but I don't know the location of the sender unit and such. I would really appreciate a how-to if anyone has performed this on a Protege. Thanks.
