Your friend was wrong. If you flashed it with the DBI flavor of NI4,
D2D would work fine. But going W2W will always work best. Especially
with Data Tach and Brake having occasional issues with some DEI R/S
models.
My initial thought was you flashed it with ADS and went D2D. That would
have accounted for the R/S issues. Being as you went W2W, those same R/S
issues could come from using the wrong signal for the ADS AL-CA GWR input.
Due to the different terminology used by DEI, their GWR signal is called
(-) Status Output. So the 4105's Dark Blue (-) Status Output wire should
be connected to the ADS AL-CA's Blue/White GWR Input wire. ( As a side
note, you can also use the 4105's Blue/White (-) Second Status Output wire
for GWR if you don't need it for the Defrost function and don't change the
factory default programming on that wire.)
While it is a bit of work to list out your wire connections, it will be the
quickest way to assist you. Going W2W is fine with the ADS firmware and
your programming steps were correct. The module should be properly bypassing
the trucks transponder system. Being as the 4105 has no alarm capability,
there will no need to use the Door, Trunk, or EBrake Status signals, nor the
Trunk Release wire. Remember that the Hood Status output will only be
available if the NV has a Factory Alarm system and a hood pin switch.
This will reduce the number of 4105 to ADS AL-CA inter-connections. Here
is a plug list for the 4105 to further simplify making a wiring chart for
your install :
