400ss - did this work? Were you able to simplify the circuit? I have a floor shifter (caddy / G8) and was hoping to recreate what you have done if it works? Any photos / final wiring diagrams would be a big help.
yes you can simplify the circuit, yes one step down,(M) mode, 1/4 watt will be ok, try to find the same ohms resistor,, corvette tune and done
