When i installed my BBK White face guages, i had to take the needles off, and there not even close to being accurate now. I put them back where they were but not even close to bein right. Anyways. I have the dual A pillar thing, and im going to be putting a Water Temp Guage and an Oil Press. Guage. My questions are, is this a hard job, im a newbie to all this stuff, so ive never done guages before, what can i expect in the difficulty category? Also what becomes of my factory guages, will i need to disconnect those? By the way these are 2 1/16 Autometer Pro-Comp Ultra Lite, Electrical Guages. Please make my day and tell me this is not a hard job!
