Well if you know bosch relays (standard automotive relay) you can wire it from one of them.
The fuel pump relay is constanly powered. So is the ASD relay.
Either one would work. They are located on the firewall BTW.
This is the standard wiring terminal designations for a bosch relay;

You must be logged in to view this image or video.

87a is powered with the key off on both those fore mentioned relays.
I'm sure either the relays in the car doesn't have the 87a terminal.
Either on the relay or the connector for the relay or both.

You can just add a 5 terminal bosch relay (make sure it's a good one 20 amp rating) Then add the terminal to the connector & use that for your key off power.
