I've installed a four gauge pod (about $40 or so from Summit Racing) where the rear view mirror would normally be in our '06 2500 Long and Tall Cargo containing the following ISS Pro gauges: voltmeter, transmission temperature gauge, boost gauge, and exhaust gas temperature gauge. I'd like to hook up the power feed for the gauge illumination so that it is dimmable from the instrument cluster + and - buttons. From reading the service manual I see that supposedly:
"• Panel Lamps Dimming Control - The EMIC provides a hard wired 12-volt Pulse-Width Modulated (PWM) output that synchronizes the dimming level of all panel lamps dimmer controlled lamps with that of the cluster general illumination lamps and multi-function indicator."
"The EMIC also provides a Pulse-Width Modulated (PWM) panel lamps dimmer output that can be used to synchronize the illumination lighting levels of external illumination lamps (up to about 23 to 30 watts) with that of the EMIC."
From reading previous threads here, specifically:

... it appears that I want to tap into a GY/DG/RD wire located at, or around, S253.
My questions are:
1. Do I have the location and wire correct ?
2. Does this wire indeed work as advertised - providing a PWM output that will dim or brighten small 12v lamps via the + and - buttons on the instrument cluster ?
Thanks in advance.
