Gauge install help

[Tackleberry]

Hey Guys,

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

Stab the one they say it is woith a test light, and turn your dimmer down and off, if the light goes out, thats it.

As far as the MAP line goes, cut it and stick the T in there

Let me find a pic of my old T I had in the MAP line.....

Here it is.

This is after I capped it off and moved the reading to the AIH plug, so that is why you don't see the boost line on it.

hey Southpaw,

The wire they said it was supposed to be isn't on my switch. The article is for an OBS truck and mine is an '03.

[Southpaw]

I would just keep sticking wires till I found the one that made the light go out when turned the dimmer off.

It's been so long since I did mine, I really can't remember which wire it was.

I am trying to get you a link from dieselmanors website, but its down right now. They have the best instructions with pics for new body style trucks. Maybe you can try going to diedselmanor.com and clicking on install sheets. My computer is being gay.

Nope, it isn't working for me either. I will keep trying. Thanks!

Not working for me either. Here is something from the Dfuser site.

On the Ford, look to the right of the steering column, and you will see a brown 6-wire connector. The
top center wire in that connector is a light blue wire with a red tracer. This is the wire you want to tap
for the gauge lights, because it is controlled by the dimmer switch. If your truck is a 2002, the connector
may be grey instead of brown, and the wire may be yellow, but regardless of color, it is always the
top center wire in that connector. Attach a T-Tap connector to that wire, and crimp a male spade connector
to the red wire coming from the gauges. Insert the spade connector into the T-Tap. Crimp a loop
connector onto the black wire coming from the gauges. Remove one of the chassis ground screws from
under the dash, and add the black wire to the other loop connectors on the post. Re-insert the screw
through the loop connectors, and tighten. For the "B" connection from the Trans Temp gauge, you will
need to insert the other red wire in any fused, keyed 12V source. Do NOT attach it to where you connected
the other red wire, or the Trans Temp gauge will only work when the trucks lights are turned on.

I think that should help me! Thanks
