DIY - 2009 Cruise Control for $10, without pulling the steering wheel and airbag - Toyota Yaris Forums

okay, i gave it a shot with no luck. I wired the switch as shown with the correct resistor values, and went to run a wire to the ecm. THat's where i hit a snag...

I thought there would be an existing wire for me to tap to. instead, i have one of those little harness plugs in the hole where pin 40 would be. how did you guys install the wire? I'm itching to do this!

Check out this other thread, starting at page 16 to see how nickjhort did it:

AAAARRRRGGGHHH!

So, i finally got a few strands of the "red" wire pulled through the ecm connector on pin 40, so i know there is a connection. the black side is grounded directly to the black battery cable.

my switches are wired exactly like described (2 switch method).

i'm going to check my resistor values, maybe i used 620K instead of 620 ohm.
