It's described in the Tech FAQ link from the thirdgen.org home page.

If you search the forum for "ALDL", you'll find pictures (from Vader if memory serves).

Re: fuel pump relay "83 firebird"

On this website http://theking.joakimweb.se/z28/felkoder.htm there's an image of a dash and just below it is an ALDL diagram. Apply 12volts to the "G" terminal. This is a great way to drain the tank.

Re: fuel pump relay "83 firebird"

On my CFI car I just jumped from the orange wire on one side on the connector to the red wire connector on the other side of the relay. pump came on right away. In fact that is how my pump is set up now with the orange wire wired to a ignition hot and the red pump power wire wired to the orange wire.
