Challenge for our electrical gurus!

OK, here is the problem / issue:
I installed a key-less entry / power door locks in the Coupe.All works, including the running lights blinking.It also has the option for the trunk popper, which I can't figure out how to connect it.Below is the wire diagram of the system, the red/black wire is for the trunk ("K" for "Kofferraum", the German word for "trunk", highlighted in yellow). But which is it? K1, K2 or K3?There is no pink wire, only the red/black.

Can somebody figure it out?    Where do I connect it to the trunk circuit??
Thnx!

Look at the wires going to the trunk relay.

I'm going to make a guess that its the red/black.  The trunk popper only has 1 wire going to it in stock form.  That's your volatage wire.  The solenoid grounds through contact with the latch loop on the body, so there would be no other wire involved.

You should connect the red-black wire on the module to the gray-black wire on the trunk relay.

Dead on!
Works!
Thanks!

I have to say, for €27.00 and free shipping, this system works like a charm.
Plus, moving the lever on one door, locks or unlocks both doors. Hence, I can retain the stock look without adding the power door lock switches.

Thanks guys.

Hmmm.  What is where the power lock switch would be?

I am curious how moving the lever on one side makes the other actuator activate.

[Donster]

I have the standard, non-power option door handles.

[Donster]

I am curious how moving the lever on one side makes the other actuator activate.

Moving the lever forces the actuator back and forth also, which activates the internal mechanism, hence both actuators, and thereby both doors.
Of course, you need to ensure that all of the internal moving parts are well lubricated. They get cruddy and hard to move over the years.

[GTRS Fiero]

Right.  I replaced my door actuators and window motors, years ago.  I have always used the buttons.  I wonder if moving the lock lever on mine would have the same effect.

[Donster]

There's an easy way to find out!

On the stock electric door locks, moving one doesn't affect the other.

This.
The instructions want you to use a relay, anyway. The trunk popper relay is already under the dash, between the column and the radio pod.

I'm not sure whether the relay has a continuous ground, and 12V is switched to activate it, or whether it has continuous 12V, and ground is switched.
(I'm sure that others are familiar. I've never had to investigate, so I don't know.)
If 12V is switched, just connect the red-blk wire to that terminal. Or to the other end of that same wire, at the dash switch.

The solenoid itself uses switched 12 volts, and is grounded through the trunk latch hook.

Steve,
I guess you didn't read the rest of it. I took Pat's advice and connected it to the gray-black wire on the trunk relay.

You should connect the red-black wire on the module to the gray-black wire on the trunk relay.

On the stock electric door locks, moving one doesn't affect the other.

So I have something unique!  And I like it!
