Just got some autometer gauges from the wife for xmas wondering what color the ignition wire was on the colum thanx guys

 

Don't look for wires when hooking up guages. Hook up to these:

 

Good day. What will happen if you connect the ignition wire at the wrong place? Ignition wire color is very important. Thanks.

 

In the ignition harness the colors for an accessory wire or ignition wire are as follow:


Accessory : WHITE/red
Ignition : BLACK/yellow
These wires will be around a 12 gauge (thicker then most wires)

(ALWAYS CHECK YOUR WIRING WITH A VOLTMETER TO VERIFY YOU ARE TAPPING INTO THE CORRECT WIRE)


You can also pull an ignition wire from the fuse panel. I don't know what the fuses are that are on ignition but you can always test them with a voltmeter and find out

 

Don't tap into a wire - there are accessory terminals in the under-dash fuse box:

Option Connector E - live when the parking lights are on, through fuse 23, 10 amps
Option Connector D - live always, through fuse 42, 40 amps
Option Connector C - live when ignition on (and not cranking) through fuse 42, 40
amps.
All 3 of these connectors are recessed male 1/4" quick-connects, and yes, you should
use an in-line fuse, especially when connecting to D or C.
