DIY Cruise Control on 07-08 Yaris (step by step)

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.
