Has anybody used these on their trucks? is it worth installing it? I have had one for a while, but never installed it and I would be putting it on my 4.7 if it will actually do any good.

Also the instructions are kinda goofy, it says to (Exactly how its written)

-Cut the MAP sensor wires.
-Connect the green to the output of the MAP sensor, a butt or insulation piercing crimp connector may be used.
-Connect the purple wire to the MAP signal input to the ECU.


Does this mean cut the MAP sensor wires and connect the green and purple wires to the ones I just cut?

Thanks ahead of time for the help

That's what it sounds like. Green goes to the Map sensor side of the wire and Purple goes to the computer side. It sounds like it's an interceptor unit (piggy back). Basically you tune by tricking your stock PCM to see a different load on the engine than what it really has.

Thats exactly what it is a signal manipulator. I have used their products a few times when there was no tuning software available. Paxton used Split Second to control their AUX injectors.

This is how it reads in the instructions:

5) Locate the signal wire that connects the MAF/MAP sensor to the ECU. Cut that wire.
6) Connect the GREEN wire to the signal output of the MAF/MAP sensor. A butt or
insulation piercing crimp connector may be used.
7) Connect the VIOLET wire to the MAF/MAP signal input of the ECU.
8) The BLUE wire is available as an option. It provides a +5V supply voltage and may be
used to power a MAP sensor. If the BLUE wire is used, the power ground terminal of
the MAP sensor must be tied to chassis ground.
9) Reconnect the negative terminal of the battery.
If

I don't know what year truck is, but on a 97 Dakota 5.2 the signal wire is Dark Green with a red. Cut this wire and connect the Violet wire to the PCM, then connect the GREEN wire to the MAP.

I have never used the ARC-1 I have always used the PCS-1. You will defiantly want to be using a Wide-band to monitor the changes that you are making.

Hope this helps

Looking at the wiring diagram it looks like the Dark Green/ Red wire is the signal wire. The Orange one is the power and the Black/Light Blue is the ground. Let me check those abbreviations for the colors though, lol.

Forgot one thing. Solder the conections and heat shrink them.

Dark green with a red signal, Orange 5V ref, and Black with a light blue sensor ground

Just cut the Dark green with red tracer wire going to the MAP sensor and then connect the green wire from the ARC-1 to the MAP sensor side and the Violet wire to the computer side.

ok, so only cut 1 wire and connect to each end of the one wire. I thought I had to connect to 2 different wires

Well what exactly is the ARC-1? Is it just something that interrupts signal or does it monitor it somehow? Does it need to have a power run to it? I really don't know what it is. Just going by what the wiring diagrams are and what I was told by you and gearhead from the directions.
