im goint to be putting in a diy4x dash soon and was looking at gauges and got really lost. i have no idea what to look for. i think i am going to get the auto meter phantom II style but other than that i have no idea. should i get electrical or mechanical, or does it matter? what type of senders do i need? how hard is it to add a tach when you dont have one,how is it done? i know that there is a lot of questions but if you could point me in the right direction i would appretiate it.
that's COMPLETELY outta control........
