Think that one would work best for automotive use... nice find by the way!
You will need to get some wire that will also hold the 40amps (that's what the circuit is fused for anyway)
Then you can tie into pin 30 and 87 and close the circuit at will!
Be careful routing the wire though so it has no risk of abrading the shielding over time.
