What water temp guage? Gotta watch out for the sender/sensor size, as the ones on our cars are japanese and most ones you buy, ie. Autometer have the USA sender/sensor size.
Boost guage, make sure no vac leaks inside the car!
Airfuel ratio, no need as they are mostly inaccurate, unless you get a wideband sensor. But loooks cool though as the lights jump back and forth lol
But that was totally offtopic... sorry I brought it up, must be the lack of wh0ring at SAU'ing ive had.....
