95 maxima command start confused

My 95 Maxima came with command start installed, 290i controller and two button remote. Pressing button one now activates the start sequence but the starter will not disengage and the unit times out and shuts down UNLESS you press button 1 again after the car starts... then the starter disengages, park lights illuminate and 1 second later the daytime running lights come on.

Install looks basic with aux 4 and aux 6 used to lock the doors and reset the alarm. There is no unlock capability from the remote. Is there a specific reason this would be done.

Not only that, last night my wife complained about the alarm going off when she tried the command start and I attributed it to being electronically challenged but when we went out, sure enough if the alarm sits for 30 sec and locks down the car, the command start only triggers the alarm. After resetting the alarm, the command start functions as described above.

2 questions then...

1... Where do I get a manual on how to reprogram the tach and what settings am I looking for. The tach wire runs to the driver's side cylinder on the front bank of injectors.

2nd... There are two wires that run from the module to the door through the left kick panel. As stated, I believe they are aux 4 and aux 6 and they only lock the car, I cannot unlock the car via the command start remote.
