Pirate! You are my hero!

I just emailed Hennessey... they emailed me back right away.

YES, they do sell the module... but, its only $199

Just bought it, I'll let you know how it works.

Thanks,

I like it Slim!

How did you run the gray wire that connects the switch into the cabin and and then under the AUX pannel?

Second question, My Cutout isn't here yet, but how did you get power to the motor? Directly to the battery?

EXACTLY!

The 8 wires behind the glovebox are like this:

4 wires from the switches. 4 wires from the engine bay.

From Engine Bay to Glovebox:

Red (thick)
Blue (thick)
Green (thick)
Purple (thick)

From AUX panel to Glovebox:

Yellow (thick)
Green/Brown Stripe (thick)
Brown (thin)
Green/Violet Stripe (thin)

In Engine Bay:

Red (thick)
Blue (thick)
Green (thick)
Purple (thick)

OK. Just think of it like this. The Red, Blue, Green and Purple wires are merely "laying around". They run from the engine bay (where you see them in your picture) to behind the glovebox. They're dead. They're as good as 4 wires just left over extra from the factory.

Imagine that YOU installed the AUX panel with the 4 switches. You have 4 leads coming off of the bottom of the switch panel. You fished them though the dash and now they're behind the glovebox, too. Connect them to make ONE LONG WIRE that terminates in the engine bay!

I guess you could think of the 4 thick wires (Red, Blue, Green and Purple) as "jumper wires", or "extensions" of the 4 coming from the AUX panel (Yellow, Green/Brown, Brown and Green/Violet). Once you connect the two ends of each of the wire PAIR that you want behind the glovebox, you'll have one live continuious wire from the AUX panel, into the engine bay.


It really is THAT SIMPLE! Just remember to connect your GROUND WIRE [black] to someplace in the engine bay.

For the rest of the AUX switches, I went like this:

Blue + Green/Brown = AUX 2 (20" LED)
Green + Green/Violet = AUX 3 (White Dually pair)
Purple + Brown = AUX 4 (Amber Dually pair)

You can feel free to connect them behind the dash (and I recommend it since they're a pain in the ass, since you're down there already) with no worries. They're terminated and weather sealed in the engine bay.


Honestly, that's what I did. It's behind the glovebox, not like it's getting wet or nasty. If it's good enough for a ceiling fan rotating at whatever RPM, it's good enough for a smooth-riding truck.


Yes. I actually used an already existing ground that Ford used for something on the truck. Look inside the engine bay, passenger side and you'll see a silver bolt going into the fenderwell. You'll see (I think) a clump of wires terminating there. I simply backed that bolt out, got some weatherproof eyelet wire tap ends and slid them over the bolt and then re-attached the bolt. I can go get a picture if you like, of where my ground is.
