PS love you pace car. I'm glad I got to see it!
I just threw that together to fake people out. Didn't spend tons of money. Car has only been out 2 years and it's getting beat up! Oh well, Just drove it 2600 miles in a little over 2 weeks. Having fun doing it.
The 2 wires for the key in buzzer are added to one of the connectors. Do they show continuity when you push the key in?
All these wires were in my head when I did my dash. I think it was all pushed out with other stuff. The Diode deal was only on one of my harnesses so I think it was optional. Most didn't have the lights on buzzer option.
