Hi.

Need help figuring this schematic out. My manual says to use it if my door unlock pulses are too long ( they are about 4 seconds right now ) but I can't figur eout ho wlong this pulse will be. if I use T=R*C then it says 2,914 secs? Is that right?

Your factory lock/unlock pulses on the motor wires should be 0.8" long.

I need to make them shorter since that .5v that shows up on the lock wires when i press unlock.

 Just so everyone knows this is on a 2008 mazda3 hatchback.
