Thanks, while it doesn't cover everything, the pictorial is a good visual reference.
The first decision would be which brand / model of remote starter. Did you want just remote start,
remote start with keyless entry or remote start with keyless entry and alarm? Some of that depends
on what your truck has from the factory. You must currently have power door locks for the R/S system
to control them. If you have the Factory alarm system, do you want to add another alarm / siren?
Viper is not one of my normal brands, so I can't advise on that aspect.
The iDatalink ( or most any combo style ) bypass module will do several things for you. First it will
bypass the trucks ignition immobilizer system, which basically is a transponder chip in the ignition
key and the the antenna and associated immobilizer circuitry at the key cylinder. During start-up,
the bypass module handles the ignition MUX wire which signals keysense, accessory and starter all on
one wire ( no need for any relays or resistors ). The bypass module takes the door lock and unlock
commands from the R/S brain and passes them to the truck thru the CAN Bus data wire connections ( again.
no need for relays and resistors ). If your truck has a Factory alarm, it controls that using the same
lock / unlock input from the R/S. Lastly, the bypass module gathers vehicle info from the CAN bus and
supplies it to the R/S. Signals like Brake, EBrake, Door Status and a Tach signal. These inputs to the
R/S make the install even easier.
Using the iDatalink ADS ALSL CH5 install guide and the Type 2 diagram with the W2W wiring method between
the bypass module and a Viper ( 5701 for arguments sake ), you would make all the necessary connections
shown by solid Red or dashed Black lines between the Viper and the iDatalink. The install in the referenced
pictorial was for R/S w/keyless only so the Door Status wire was ommitted. (The Viper 5701 would use that
for its alarm system.) Also not used was the EBrake Status and Trunk Status.
In W2W mode, the D2D harness is not used and the 3 wires shown at that plug are hardwired. The GWR
Blue/White would connect to the Vipers' (-) 200ma Status Out Blue wire ( H2/10 ). From the Viper, the
H1/2, H3/6 and H3/9 would all go to +12V constant and of course H1/5 to chassis ground.
The hood pin is usually supplied in the remote starter kit and installed by finding a good location,
drilling a hole and screwing the pin into position. Adjust the pin height for proper operation and
connect to R/S Hood Status input wire. This is an important safety feature as it insures the engine
can't be remote started with the hood open ( if the engine is running under remote start and the hood
is opened, it will immediately stop the engine, too). The hood pin is also used for the alarm system
to monitor that point also.
As for wiring info, the iDatalink install guide is very accurate for all of its' vehicle connections.
For the other R/S to vehicle wires, here are some links to help. Remember that these are only guides
and there can be errors / conflicts. Always verify with a Digital Multi Meter.
