DISCLAIMER: I KNOW NEXT TO NOTHING ABOUT WIRING. A friend of mine helped me get as far as I am right now. He lives 2 hrs away and our work schedules don't mix very well, so I am going to try and finish myself. I am no meat-head, just don't know much about wiring stuff up.
I have Autometer Ultralite 2 gauges
I am part of the way done with my gauge install. We ran out of daylight (and wire) when we were wiring them in.
The gauges are in the pod and the pod is in place,
the sensors are in the exhaust and trans
the sensor lines are run through the firewall (not prettied up yet)
I have the Diesel power article (Jan09) on the gauge install. They wired the gauges to the dimmer switch on an OBS truck. That way the gauge pod dims with the stock gauges. They also "t-d" the Boost gauge's vacuum line into the Map sensor line. They used the 15 amp radio circuit to get positive juice and grounded the gauges at the e-brake bracket bolt.
So let me get this straight:
1)I run all 3 grounds of the gauges to 1 common ground that runs to the e-brake mounting bolt
2) I run all 3 positive lines to a common positive that runs to the stereo circuit
3) Then I wire the gauges to the dimmer
So question 1
1) Which one is the dimmer wire I want to splice into? And how do I wire my gauges to dim if I am already running the positive line to the radio?
2) Where do I get the "t" to "t" into the map line? Do I just clip in half way and insert the "t"? will shortening the boost sensor line affect the reading?
Thanks for the help
