86 Maxima door lock headache problem

i'm working on a 86' nissan maxima, installing a Sting Pro alarm system and headunit and an amplifier. The problem with the headunit is that after i took off the stock headunit the stock wire harness didn't include any of the speaker wires, does anyone know where it is i can't seem to locate it. I know that there is a stock amp, i think actually, could this be the reason why there isn't any speaker wire connection behind the headunit? Also is there a way i could change the stock headunit for an aftermarket pioneer, but still keep the stock amp to power my front and rear speakers instead of having to get another amp? Also for the alarm i couldn't figure out how to get the power door locks and door unlock to work with the alarm. I can't seem to find the wire, any help will be greatly appreciated...Thanks in advance.

What do you mean by actuator, the car already has power door locks, when i light test the wire one was +12v another was +12v trigger when the unlock was pressed and other one was negative trigger for lock. I really need to finish this car today, so any assistant will be greatly appreciated. Thanks in advanced.

Here are the door lock wires:

POWER LOCK|ORANGE / red (x2) *1  |-  |below package shelf        
POWER UNLOCK|org/blk and wht/blk |-  |below package shelf        

* 1 These are colors for cars equipped with keyless entry (keypad on door). For non-keyless cars, look for a blue/red wire (5 wire) for unlock and a WHITE/ black (-) for lock in the drivers door.

For the speakers you will have to run new wiring into the car if the vehicle has an OEM amplifier ( which my notes tell me it DOES NOT ).

actually it does have a stock amp under the passanger seat it think, but what do you mean by "Keypad on door"
the car doesn't have a keyless entry i don't think but it does have a all door lock and unlock on the driver door and also the blue/red wire on the driver door is +12v triggered to unlock and WHITE/ black is negative triggering to lock, can you explain exactly how to hook this up the alarm comes with a central locking interface connection which has 3 wire for unlock and 3 wire for lock, the 3 wire represents NO, COM, NC.

well i finished the stereo by testing wire from the stock eq and all the speaker wires were there so i just chopped them and connected them to the aftermarket headunit, works fine. Stereo problem solved, but alarm is still giving me a headache.
Still cannot figure out the door lock problem never came across this before. the problem is how do i get the alarm to lock and unlock the doors? I tried locating the orange red and orange black but don't know where exactly to find it....and where exactly is a below package shelf, i'm not familiar with this.

I realize that on the 86' Maxima it has a positive trigger to unlock the doors and negative trigger to lock the doors and also notice if i just try to lock the car i hear a relay noise from under driver seat and but same doesn't happen if i unlock doors. If someone could tell me exactly what to do, location, color, in detail what to do, it will be greatly appreciated. Come on one of your experienced pros help me out, my hairs about to fall out from being so frustrated. Well cause i'm not getting paid unless i finish the job. Help...Help...
