" Regarding p/n 11-03161, be aware that with the master relay in the battery positive lead circuit, as is commonly done, to actuate the relay coil you must provide a negative/ground connection to the coil terminal (not a positive) from your master switch or key switch. If this is inconvenient, a small control relay can be used to actuate the master relay, activated by the master/key switch."
