Second ignition is a small gauage white wire and so is the yellow starter wire, test carefully.

Everything else is also at the bcm, door locks are in the far left plug, factory disarm is in the far right plug

and parking lights (-) are in the middle plug.

Brake wire can also be found at the ignition harness, white wire (+)
