Notes of the relay wiring
The relay wiring of pump: oil connectors of both ends are a fine white line (85) and a fine
Green line (86). The fine white line (85) is connected to vehicle positive power (+12V). The
fine green line is connected to the device relay control line.
Cut off the positive connection line of the pump; then connect in series to the relay N.C. contact
(thick green line 87a) and the other end to relay COM contact (thick green line 30).
Note: The standard relay is 12V and only suits the 12V car battery. Please choose 24V relay if it
is 24V car battery.
