going by those color codes i messed up.........step one - you can hear/feel the relay change state when you use the toggle switch or turn on/off the car. always check that first.
step two - measure voltage across the ELD. this is basically done between relay pin 30 and the black ELD ground wire. the pics in my thread with dual meters used some wiring from my ELD wiring intercept into the car. normally, you won't be able to do that as easily. for the thread, i wanted to demonstrate what voltages you should see.
