K jetronic Injector test

[hoolio]

Hi all I have a 91 b3 16v quattro that I'm getting back on the road after sitting for 12 years and would like to check and flush through the injectors. I've found info on removal , spray pattern and measuring but cannot find details of which relay to pull and which way the bridging tool goes. Any help much appreciated. Thanks

This is sorted now I pulled relay 208 pulled the injectors bridged the relay and lifted the flap on the metering head. Eventually got a good delivery of fuel from each injector. But no spark back to it.
