Hey everyone, i am wanting to put guages in my truck, but need some help on where to hook everything up at. I want to put a vaccum guage in there, a coolant temp guage, and an oil temp guage. Where would be the best places to run them? the coolant guage... can it be run to the stock water temp spot? where is that located? the vaccum guage... do i just run it to one of the vaccum hoses? how about the master cylinder hose? and the oil temp guage... whats the best to do with that? is there a way to run it in the drain plug or something? or do I need to drill a hole in the side of the pan? any tutorials? thanks for the help.

Oh and what about these PLX OBD II guages? they any good? should I just get one of those and call it a day?
