i have a 95 hardbody and im trying to convert my old outdated manual slide type a/c controls to a newer modern electrionic caontols....i know i need the motors to move the flaps and the control panel with a pigtail still on it so i can wire it up....what i need is a diagram on the wiring on the control panel itself so i can know whats what coming in and out of the panel....im also considering just yanking the whole air duct assembly from a qx4 and stuff it into my harbody, but if i can just as easily adapt the motors to whats already there that would be good...also i know these controls wont mount into my truck at all...i have already moved my existing a/c controls to where the radio came from the factory and moved my single din size deck to where the control where but now i want to totally redo the panel and do a double din indash nav unit up high and mold in the a/c controls down low....any help or guidence is greatly appreciated....thanx in advance..............................albert

ok well i just downloaded and looked over the fsm on the 99 qx4 and that looks rediculously complicated to transfer over to my truck...so is there any others out there that have the digital display and is electric that doesnt have to go through all the modules and a micro computer.....

Having had the dash out of my truck, I can say it would be a major undertaking. I know the 99 QX4 is on a different platform than the D21 style hardbody truck. I don't think there are any other Nissan climate control systems that don't use all of those modules and mix doors and sensors... it is really a pretty complex system.

Either way, if you do take this on I would love to see pictures!

well after looking at the diagram a little closer it doesnt seem to bad of a conversion....im a mobile electronics installer so the wiring i feel at home since security is my specialty....but i cant seem to find a schematic on what wires go to what on the harnesses that plug into the control panel..i.e. which is power in and ground in and which ones go out to the sensors and which goes to the motors...really i need a pin diagram if anyone can get it....im used to using diagrams with specific wire colors doin specific functions...so if i can get the schematic in a pinout form i will well on my way to pullin this off...

As far as I know, the only wiring diagrams are in the FSM, like the one you downloaded.
