I am in the process of installing gauges for egt, boost pressure and trans temp. My question is where to pick up the electrical connections for power and a switchable source. Also need to pick up a source that works with the dimmer. Thanks

I found a fuse that came on with the key in the fuse panel by the driver's door.

Just bringing this back around with a question for somebody in the know... http://www.dieselmanor.com/diy/CMS3-gauge/G3image4.htm My existing (and yet unused) pyro port is located in almost that exact location, but maybe 2" further towards the back of the truck. When they say the gauge will read "significantly higher" if located there... what kinda significance are we talking about? Will the pyro gauge even be accurate in this case? Thanks...
