Correct... see rfmaster's circuit diagram in post #108. The only caveat is that the light you use should not be a grounded internally to its mount or it will be on whenever IGN is on.

THe computer turns on the ground for the light so you can have a full time 12 volts to the light but it will not come on untill the computer turns on the ground for A-5. This is how I have mine run. I also used the place for the choke light because that is where GM put the check engine lite from the factory. (except ofcourse it says check engine soon not choke)

As for the vss you will keep getting a ses light untill you install one. Ask me how I know .
