CTScott, If you're willing to sell the switches and the resistors all ready wired for the two switches configuration, I'll be willing to buy them of you.

CTScott, would these resistors work?

Radio shack part # 271-1117
680 ohm 1/2W 5% Carbon Film Resistor pk/5

or do I need the ones in the value pack,

also will these switches work.

Radio shack part # 275-1571
SPST 0.5-Amp Momentary Switch (2-Pack)
One red and one black. Rated 0.5 amps at 125VAC and mounts in a 3/8" hole.

or are these better

Radio shack part # 275-609
3A 250VAC momentary switches normally open

And my last question, if the vehicle goes for service, I assume all this would have to be pulled out as it would most likley void the warranty? Thanks in advance.

680 Ohms is fine. The 1/2 watt resistors are physically larger, but are fine.

For the switches either is fine. I used 275-644, but really any normally open momentary switch is fine. You are switching 0 current, so the rating really doesn't matter.

As far as warranty goes; Unless the dealer can prove that your DIY cruise control actually caused something to fail, they can't say that you voided the warranty.

I could. I would just have to find switches that mount from the rear, rather than front, so you could just drill your holes, poke the switches through, connect the wires, and cruise.

One of the switches that Opto101 mentioned above, would work for that:

the ones pictured above are tiny, just got back from radio shack and after seeing them in person, I went with the 275-644

Much better option

Off to find pin 40 now, will update with photos and status

Worked out great!!! Thanks to everyone, especially CTScott for the further incite, and everyone else who made the how to pdf! I opted for the 2 button set up as I drive a set speed during my commute. The parts where easily obtained from my local radio shack.

Parts list:

Qty (1) Radio shack part # 271-1117 680 Ohm 1/2W Resistor

Qty (2) Radio shack part # 275-644 3A 125V SPST Pushbutton

12 Feet of wire

Ground loop terminal

All together I was just under 15 bucks

I used the grommet on top of the ECU for easy access to the interior.

My only concern is I put the wire into pin 40 and let a couple strands come out the end of the main harness connector as depicted, re connected it to the ecu, but I was wondering will the wire in pin 40 just stay there, should I try to put that rubber piece I removed on the side of the wire so to make sure it stays put or don't worry about it?

Here is my dash install

I also used a hot glue gun to make sure everything stays put behind trim piece.
