Could send the details to the group?
My 94 940s are factory pre-wired for keyless entry and alarms.
Wiring diagram sent separately.
The first thing you need is a lock motor. (see SWITCHnMOTOR.JPG) The one with
the blue wire sheath is the motor.
The second is a Keyless entry controller. I bought one on eBay for $25. Next
time I’ll spend $45 and get better security codes.
The third is .187†wide Quick Disconnect pins from Radio Shack # 64-3132
They are a tight fit but you can use them in the plugs below.
Under the dash there are two plugs taped to a harness to the left of the
steering column. D3 has 4 pins … D2 has 8 pins
D3 Pin-1 Red Wire .. +12v from fuse 2
D3 Pin-2 Green/Red .. +12v from fuse 5
D3 Pin-3 Blu/Red .. +12v from fuse 9 with Ignition sw in RUN position
D3 Pin-4 Black .. -12v (GROUND)
D4 Pin-1 Green ... Left Turn Signal
D4 Pin-2 Blu/Green ... Right Turn Signal
D4 Pin-3 Brown/Black ... Ground when any door is open
D4 Pin-4 Yellow/Black ... Lock (ground to lock)
D4 Pin-5 Green/Black ... Unlock (ground to unlock)
D4 Pin-7 Brown/pink … To pin-2 of plug D4 Under hood left side
D4 Pin-8 Greenn/White … To pin-1 of plug D4 Under hood left side
I assume 7 & 8 are for a siren
D4 Pin-6 Brown/Orange … Ground from Station Wagon Hatch
I used D3 1 & 4 for power and ground
And D2 4 & 5 to operate the locks.
PROCEDURE
1. Make sure you have the radio code
2. Disconnect the battery
3. Remove panels under the Dash
4. Find the plugs. They were taped together with masking tape next to the
steering column above a harness. (See pictures)
5. Connect to the plugs
6. Route the antenna wire ( I ran it up to the dash at the A post)
7. Plug in, connect the battery and test
Note! If you have not put the new lock motor in yet the remote will only be
able to do the opposite of where the drivers lock is.
Exchange the switch on the drivers door lock for a lock motor.
They look and mount the same. The motor plugs into a two conductor plug
instead of the three conductor one the switch plugs into. The best way to do
this is;
Go to a U-Pick junk yard for a couple lock motors and practice in a junker. I
think the lock motors were used for several years in 740s and 940s.
1. With the window UP, take off the door pad. (If you don’t know how let
me know.)
2. Take off the latch. (On the end of the door. Two big torque screws.)`
3. Note the short screw under the latch. Leave it in for now.
4. Remove the two screws below the latch. They hold the plastic window
channel.
5. Find and remove the other window channel screw. It is a sheet metal
screw near the windowsill. See the picture of the channel. It is at the top.
6. Reach inside the door and pull the channel down and let it lay in the
bottom of the door.
7. Unplug the switch and cut the tie-wrap on the wire. The motor plug is
taped up about 3†away.
8. Reach inside the door and disconnect the levers from the lock assembly.
1 from the key 1 from the exterior handle and one from the interior handle
9. Remove the small screw that you noted under the latch. The lock
assembly will now come out.
10. Swap the switch and motor.
11. Put the lock assembly back in. Use the little screw under the latch to
hold it in place
12. Plug in the motor
13. Put the door back together.
