if i were to just get an mbc and then get a gauge, would all of the wiring needed come with the mbc? and can i mount the gauge somewhere else without having to get an a pillar gauge mount? haha short on the $$$$
do yourself a favor and research very heavily the parts you plan to put on your car...If you are just putting a gauge and an MBC so you can up the boost with all your other engine parts stock you are in for trouble...
the only wiring is for the backlight of the gauge so it lights up when you turn your lights on (check the how-to i sent you for directions). for the mbc, there's nothing really needed except maybe a lil' vac line, you just insert it between lines -- again, how-to.
