stock to autometer wiring

moparlover said
my autometer tach must be different. it has 4 connections, GND LAMP SIG 12V
12V goes to keyed ign 12v source and SIG goes to the tach wire from the MSD

other thing i'm doing different... every gauge has an incandescent bulb with a little green condom or a little red condom. i got LED replacements (i wanted amber, they have 99 different colors) the only funny thing about the LED's is you have to try them if they dont work flip them because they have a +/- that are not labelled

will post a link for the source where i got the LED bulbs
www.autolumination.com

they are "194" bulb replacements, be sure to get the "inverted" since they are wide angle

look for "194 168 W5W 2825 Inverted Lenses"
on this page (close to the bottom):

No you are correct. The TACH does have four terminals. One is the signal which I need to run to the MSD and the other is 12V which in my case can be tied into the BLUE w/WHITE TRACE to work off the ignition switch. Also, I need to state that I originally bought what is known as the Designer Black II gauges. These are exactly the same as the Designer Black but the Designer Black are analog gauges and the Designer Black II are the LED gauges. The LED are built right into the gauges. My issue was that the Designer Black II that I bought in the FUEL GAUGE was not the correct 73 to 10 ohm rating and they did not make it for that rating. So rather than undo all the gauges, I had to buy the Designer Black Analog, which does come in 73-10 ohms. Only problem was that the analog light bulb would be a different white light, so I am just adding the red/orange cover to that one gauge so at night it will light up RED and the rest will be white. I think that will be OK and just be a look I chose? I will definitely make changes to my original post to include your information. Thanks for the input. I hope this is helpful to others.
