anyone who has put autometers in dash, help!

[low 84]

well i'm going to start on this soon. not this week but after my next couple pay checks. a NEED a new temp gauge soon and NEED the tach. i'm going to start off with just 3 guages. big tach, small temp guage, and small fuel gauge.

i'm only doing three for right now b/c i can't afford all of them. when i buy the other three i will also get the painless harness and wire them nice, but for now i'm going to hardwire/splice the first three in.

so here are some questions.

fuel gauge - when wireing this do i have to run any new wire to the tank or can i simply tap into the old wires that went to the old fuel guage?

temp gauge - same question, can i just tapinto the existing wireing and does the temp gauge come with a new sending unit?

tach - i know this one

can those who have done it post all the pics they have of it. front, back ect.

i haven't decided if i want to completley recess them like mikes or leave the faces outside like eddies.
