(–) Ground Input
The RED wire is the (+)12v power input to the
1480. Be sure to connect this wire securely to a
constant
12v source, such as the factory wire at-
tached to Pin-16 of the car’s OBD2 connector (see
OBD photo at bottom of page 8).
As of this writing, Toyota, Lexus, the Subaru BRZ and some Nissan cars do
not put the factory OBD connect to Sleep to save power like some European
cars do, so you shouldn’t have a problem 12v from Pin-16 of the fac-
tory OBD. However, car makers can change their body computer at any time.
So if you find the 1480 shutting down when it should not, your Power and/or
Ground connections must be suspect. If you have doubts about whether the
OBD is being put to Sleep, run an extension wire through the firewall and
attach the 1480’s RED wire directly to the po12v battery terminal,
which will bypass any Auto Sleep features of the vehicle.

Pages 9-10 describe how to
MANUALLY CONNECT
the Power & CAN
wires. You do not need to reference these 2 pages if our Compatibility
Chart says your car can use OBD, unless you wish to cut off the OBD
plug to hide your connections. For Honda 1-wire, note pg.10. For all
other cars, refer to our separate Install Guide.
If this section doesn’t
apply to your car or installation method, skip to page 11.

The BLACK wire is the (–) Ground input to the 1480.
Be sure to connect this wire securely to a good ground
source.
Most security system installation problems
result from a bad ground connection!
The easiest
connection is to the factory wire behind Pin-4 of the
car’s OBD connector (as shown in the photo on page 8.)
And unlike Pin-16 (+12v) of the car’s OBD, Pin-4 (Ground) is normally not
put to Sleep by some body computers. If you have doubts though, you can
connect to body metal or an existing bolt (brush with steel wool first), or you
can run a wire directly to the car’s Negative battery terminal.
