The SAM switches relay 9 on
supplying power to fuse 13
when the headlight switch is
on! thus turning on the trailer
tail lamps.
When in emergency power
mode , the SAM switches relay 9
on and off, which switches the
power to fuse 13 on and off!
thus flashing the trailer tail

lamps.

NOTE R 9:

BAT

R8 is a single throw relay, it will
only have 4 prongs. Either pin
87 or pin 87a will be missing,
depending on the intended
functionality of the circuit.
If prong 87a is missing the
circuit will be normally open, the
trailer power circuit is enabled
only if the key is in IGN position
or enabled through a switch
(depending on SAM
parameterization)
If prong 87 is missing, the circuit
is normally closed ( BA T).
If a 5 prong relay is used, the
trailer power will be always on.
