hmm, you still need to use a diode b/c the hood pin itself will send a ground signal back to your ECU.

test it by metering your tapped ECU connection with the Hood Pin grounded. it will show ground even if your gear shifter is in neutral! your ecu will think the vehicle is in gear though the gear shifter is in neutral.

1 amp diodes aren't expensive, 10 cents perhaps!? and it will protect your ECU from getting an improper ground from the hood pin.

It works great!

The only problem is now I don't get to see the confused looks on people's faces when I used to get out of my car with the engine running and then have the engine and headlights shut off magically.
