Not needed ... the test is a direct connection of bat power to starter solinoid.
This is a diagnostic trick to eliminate the starter/sol. circuit before getting into the chain of starter circuit power of NSS and ATA systems..
[ starter/sol. verification, if you will - just a good place to start diagnosis due to the ease of the connector location.. ]
