Hi, my name is shane, I just bought a new 2006 Saturn Ion 3 with the Enhanced Performance Edition, I have just installed a short shifter and a AEM cold air intake, and now Im trying to install a Faze 5' aftermarket tachometer, and anoil press gaugebut I dont know were the signal wire for the tachometeris or were I could even begin to look for it, and I dont want to pay 250-300 dollars for the repair manual, can anyone help out please, thank you.

First, doesn't the Ion already have a Tach? Why do you need another? However, if you do want the extra tach, you could buy a Hanyes manual for about $20 and the wiring diagrams in there will help you find the connection you are looking for. They are very helpful for most maintenance and repairs to vehicles.
