start button C40 to switch ground to pin D3

[rusefillc]

implement that when voltage arrives at pin C40 to switch ground to pin D3? With this the car could be started by key without hardwiring the starter

[rusefillc]

D3 is P5 "starter lock-out" we have a via, let's jump to P35 "low12"

C40 is P3 "start" we have a via. Let's connect to RES2 P31

@Qwerty-OFF what is a good input to feed this into?

[rusefillc]

rev C change 1: connect D3 and OUT_LOW12

rev C change 2: connect C40 to RES2 as "start button"
