Fuel-pump and shorting relay...?

Wanting to test all 4 injectors and check their spray-pattern for conical and similar shape/quality, I am repeating a posting I had here two days ago.
Testing requires you pressurize fuel-system by running fuel-pump, as if the engine was actually running. This is for me the tricky part now.
I am the lucky owner of an 8-valve B2012i fitted 1990 5-door SAAB900. Can anyone specify for me how to get the fuel-pump to run (- after you have disconnected ignition-coil and removed the air-duct/boot) for more than the initial 1 second after turning the key to run position?? I believe it comes down to wire-assisted short-circuiting terminals in the fuse-box, but which of the 4 connecting the fuel-pump relay do you target??
Last time, tow day ageo, I got some information, but noone specified exactly what relay-terminals in the fuse-box to connect to shortcircuit but not blow the circuit.....
Thanks, Mike
