Hi, could someone please help me with my 93 Ford Tempo keyless entry installation?

I am having trouble getting the lock / unlock to work with my Omega REC-11 keyless entry. I also have 4 bosch relays available.

I think that I have "5 Wire Alternating (+) 12 V DC"  I'm pretty sure that the pink/green wire is lock, and the pink / YELLOW wire is unlock.

This is how I currently have it wired:

On each switch, 1 wire is constant 12 V, one is the unlock wire, the other is the lock wire, and 2 are ground wires.

I have tried hooking it up many ways, but the relays just make clicking noises, and nothing happens. PLEASE PLEASE PLEASE help!!  I have already spent a whole weekend trying to get this working.  ****Whoever helps me the most to get this work, I will give $20.00 using PayPal.**** (no lie)

Your car has a (+) type door lck system. If your alarm has alternatinf polarity door lock wires, then hook straight up to the alarm otherwise you will need this diagram to hook up the door locks to reverse the (-) signal from the alarm: https://www.the12volt.com/doorlocks/page3.asp#3wp

Ok, I couldn't get it to work with the information that you gave me.

Here are some more details about my installation:

On each door switch, I have 5 wires.  The pink/green wire rests at ground and shows 12 V positive when I hit the lock buttton.  The pink / YELLOW wire rests at ground and shows 12 V positive when I hit the unlock button. There are also 2 ground wires and 1 constant 12 V wire on each switch.

My keyless entry system has negitive lock and negative unlock outputs.

When I tried hooking it up using the diagram you gave me, I got a high pitched squealy noise from the relays, and it didn't work. When I tried hooking it up straight to the keyless entry system, it did nothing.

I have also tried hooking it up as "5 wire alternating 12V positive door locks" with no luck. (maybe I'm hooking it up wrong???)

One more question.... What is "the optional DLS"??  In my manual, it recommends that I use this, and it also says that "some doorlock systems, however, require more than the 500ma ground output that the keyless entry system's control module can accomodate". So do I need to get one of these or not?  I don't know what this "DLS" thing really does...

Whover replys next, could you give me some extra details?? This is my first time installing one of these, and this message board and my instruction manual assume that I know what I'm doing (and I don't)

That $20.00 offer on PayPal still stands if anyone can help me get this working.....

First thing you need to do is make sure your outputs from your RKE module still work, they may have been fried. To do this take you DMM or test light and clip your positive lead to 12V+ and clip the other lead to your lock or unlock wire on your RKE module. Now use the remote and trigger the lock or unlock. If your module is still good, your DMM will flash 12V+, or your test light will flash.
After that, find your target wires (pink / YELLOW, pink/green) and cut the wire. If you have the right wire, when you hit the button on the door it won't function. Now you have to find which is your motor side and which is your switch side of the wire you just cut in half. Take your DMM or test light and clip one lead to ground and the other lead to the side of the wire you are testing. For the pink / YELLOW, when you hit the lock button on the door, if you have the SWITCH side the DMM will show 12V+, or your test light will flash. If you have the MOTOR side of the wire nothing will happen. When you have figured out which is the motor side and which is the switch side label it or just remember. *A quick test to find the MOTOR side of the wire is to supply it with 12V+, if you have the MOTOR side the door lock/unlock function will work.
Do the same procedure on the pink/green unlock wire as well.
Now get your relays wired up as follows:
lock relay:
85 -> Green on RKE module
86 -> 12V+
87 -> 12V+
87a -> pink / YELLOW SWITCH side of vehicle
30-> pink / YELLOW MOTOR side of vehicle
unlock relay:
85 -> Blue on RKE module
86 -> 12V+
87 -> 12V+
87a -> pink/green SWITCH side of vehicle
30 -> pink/green MOTOR side of vehicle
*Remember that when you cut the lock/unlock wire in the vehicle, that function no longer worked when you hit the button on the door. If you have the relay wired up correctly and connected to you lock/unlock wires, when you hit the switch on the door that function should now work again, if not check to make sure your relay's are wired correctly.
Now try your RKE, it should work, if not you may have the SWITCH and MOTOR side backwards.
I tried to go through this step by step, I hope it helps.

Thanks a lot,

I have done what you have said EXACT once before, so it IS possible that i have fried something...

THANKS A LOT....If I get this to work on saturday night, I'll owe you 20 bucks. (I appreciate the extra details)

Ok, i tested the positive / negative outputs on the RKE module, and they are between .5 and 1 volts......I think it's fried....(the lock / unlock wires from the RKE should both be 12 volts..right??)

If it is fried, i'll just buy another one....they aren't TOO expensive....

I'm not sure on how many volts they put out? Is it enough to energize the coil in the relay?
Quick test to find out would be:
85 -> lead from RKE
86 -> 12V+
87 -> positive lead of DMM/test light
87a -> not used
30 -> 12V+
then connect your negative DMM/test light lead to ground. Use your RKE, if it's still good it will switch the relay and you'll get a reading on your DMM.

I've got another question.............

Uhm, I'm not so sure that I've got "5 wire alternating 12V positive door locks" because when I supply 12 V to the motor side of the cut wire, NOTHING HAPPENS!!!!

What does it take for me to activate the lock manually?? (without pressing the button on the switch) Remember: I have 1 lock wire, 1 unlock wire, 1 constant 12 V, and 2 ground wires on each lock switch.

The relays made a high pitched, squealy noise when I pressed the lock / unlock button on the remote (so it was obviously the wrong way to hook it up).

ALSO, I HAVE BURNED OUT THE DRIVER'S SIDE DOOR LOCK SWITCH BY WIRING IT AS "5 wire alternating 12V positive door locks", AND I HAVE ANOTHER SWITCH BEING SENT TO ME SPECIAL ORDER BY ADVANCE AUTO PARTS.

I have tested all of my equipment (RKE, and 4 relays) and they all still work (nothing is fried) , I'm just not wiring it correctly.

Please, someone help me figure this thing out!!!! (IT IS DRIVING ME CRAZY)

OK... where are you grabbing the wires from ?? In the door switch between the motor nd the switch or between the switch and the relay ?
