Stupid question (how to hot wire IC pump)

[Spencer]

How do I hot wire the IC pump to turn on when the ignition is on? I grounded one of the wires on the relays located on the firewall but that wire made it run all the time. Is there a specific wire that will only turn it on when the ignition is on?

For anyone interested its the yellow wire on the drives side relay.

yellow to green, right?

 

[GM TURBO]

Yellow to ground is easier.

yea, just run a wire spliced off the yellow to one of the firewall bolts and us an o ring crimp connector, pretty simple, other then trying to get a cheapo scotch lock on that wire when its tightly in place that is.
