Where do you get the idea that a 928 central locking button is the way to go - it isn't - it won't work... I post because its likely misleading to others to mention it...

The alternating central lock button function is a problem - as is the fact that it is anyway non-operational with the ignition off - it only locks the car in that mode - not very helpful...

On a Ford/Chevvy or similar the 2 way (lock/inactive/unlock) button is a possibility - on a 928 you need the individual lock/unlock wires to the locks (commonly available at the alarm or central lock modules)...

Keyless entry is easy to install on any electric lock 928 - but all the existing equipment has to work correctly... This won't solve a lock or hatch opener that already doesn't work...

Where do you get the idea that I want to do that? I simply said that I was having trouble hooking it up because I fail to see where that misleads anybody! I do not want a central lock button, I never have used the one in my 944. I now have two early 928's that I am trying to put remote locks on and I am trying to get some help. How bout if it's so easy just telling me where I can find my answer; search hasn't been my friend on this. Everybody seems to be putting remote start, alarm, heater, hatch, flashing lights, etc, etc ,etc on late 928's. I'm just wanting remote lock hooked up to my stock working system.
Thanks

 

Well I suppose it would be because you said Folks with 928's with central lock buttons may think thats the best way to install one...

This seems to be a rather odd way of asking for help...

Well, let me be more precise: Where do you tie into the door lock system on a MY 81 & 83 to install remote door looks?
Thanks

 

Be cool towards Alan. He is the electrical Savior. Meaning it or not it did sound demanding. Shake hands and go back to being friends:-)

 

You should only need to hook up the included antenna, power(30) & ground(31). Lock & Unlock for basic function - ignition and interior lights are not needed at this point
On an 81 & 83 you will need to configure for positive & short locking pulses. If your unit doesn't support positive locking you will need 2 additional SPDT relays for this.

Try to see what the pulse lengths are for locking - its important they not be too long...

You will need to connect to the 2 central locking wires between the doors - you only need to attach in one place so nearest to where you install the unit. You need the Yellow & Green/Black wires that go to the locks - you will probably have to open up the doors to find them (they are not available at the central electric panel).

Connect lock & unlock outputs (or the equiv. relay outputs) to these - I'm not sure which way is which - I suspect green/black is unlock - try it and swap them if needed. The feeder to the locking relays (or whole unit if positive is configurable) should be fused with a 1A fuse.

Get this working first... Assume you don't have an electric hatch opener on either car? What else do you want to do - horn honk for confirm, lights flash, interior light control?

Thanks, I spent most of yesterday fooling w/this and I was really at my end of it. Didn't mean to sound short or anything; it would be very difficult to maintain these cars as 'easily' as it is without Rennlist and the members on it.
I think I am hooking it up like you say, but I just may need the extra relays. The yellow & green/black wires lock/unlock when you ground them. I assume the remote is supposed to ground them thru itself.
I will try again later, since your advice is similar to the instructions but car specific, I should be able to figure it out.
Thanks

 

Actually I was mistaken - negative locking is needed - most KE's can support this directly (I was looking at some diagrams that don't agree with the factory wiring diagrams... ! Since you've tested it you know which is which already...?

I have never installed one on a pre '85 car - but it should be no major problem to get it working.

The wire colors and other instructions I mentioned are correct - go for the shortest pulses possible on your system - and only go longer of that doesn't work...
