Installing the Viper 5904 / Python 594 / Clifford 590.4x Alarm
The installation manual that comes with these systems covers everything you
need to know so I will just add some suggestions for where to locate things.
The Brain (main unit). Best location to connect to the ignition harness as well as
the remote start wiring seems to be directly behind the glove box in front of the
A/C unit.
The Antenna, Valet Switch & LED. These are a combined plug in module
designed to mount high on the windshield. Wiring can be routed down the
passenger side A pillar.
The Remote Start Disable Toggle / Optional remote start/turbo timer push button.
These can be mounted anywhere convenient. Personally I’m not a big fan of
drilling holes for switches and prefer repurposing OEM switches which aren’t
used in the spyder such as the headlight pop-up switch (under fog light) or a rear
wiper switch.
The Hood Switch. This one is simply not needed if you follow my wiring guide to
wire into the stock hood switch.
The Shock Sensor. This one is built into the 5901 but is external for the 5904
series. If external it can be mounted to the A/C unit behind the glove box.
Adjustable from remote.
Optional Field Disturbance Sensor 508D. This is a great option for convertibles
and has separately adjustable warning and alarm zones. Under the rear seat in
front of the seat belts was a good location. This device works with both 5901 and
5904 however requires external 12V / Gnd powering for the 5904 application.
Bitwriter ESP port. While many features of the alarm system can be
programmed using the valet button, many others need the hand-held
programmer to access. It also makes programming much easier. If you run an
optional bitwriter cable (8998 standard; 8999 molded) to a place easily accessed
later (I put mine under the gearshift boot) – you can change programming easily.
Magnetic Switch. No need for a relay – connect one lead from magnetic switch
to Neutral Safety (-) input of alarm and other lead to ground. Note these alarms
have a manual transmission mode which doesn’t rely on this input, but requires a
rather convoluted procedure to arm remote start. I used the magnetic neutral
safety switch and programmed the alarm as an automatic transmission for more
convenient operation.
