So this week I decided I was going to wire in a keyless entry remote unit to the vert. for those that don't know how the locks work on our cars, there's 2 wires leading from the inside lock knob on the driver's door. One is a ground and the other is a signal wire (orange/black).When the knob is at the unlock position, it completes a circuit that tells the doorlock timer to unlock both door actuators for 1 second. When the knob is set to lock, it breaks the circuit, which the timer recognizes as the signal to lock both door actuators for 1 second.
Pretty simple, no?
In the 89-90 model 240s, the knobs had 3 wires. Ground, lock circuit (Or/B), and unlock circuit (Orange/Blue). This system worked by having the Or/B circuit complete to lock the doors, and the Or/L would unlock them.
So I grabbed my trusty service manual and pulled the glovebox and frame out of my car to get ready to tap into the wiring going to the door lock timer. Being a '92 model, I expected to see the one wire setup. However, I was greeted by both the Or/B and the Or/L wires. WTH? I figure, well I have the old style of system. No biggy, wire the unit up like you would to an '89. No dice on that. The car unlocks, but won't lock.
After I do some testing, it turns out that the Or/B wire acts like a single wire setup, but the Or/L unlocks the doors as well (it doesn't relock them if you sever it's circuit continuity, though).
My only guess is that since my car was produced in '91, Nissan decided to use the verts of that year as trash bags of old parts. It was a limited edition run, so why not get rid of all the old pignose era stuff? So the chassis harness must be out of an 89-90, but the locking system is the newer setup from the '91s. Thanks Nissan!
