Electrical wiring - rear end extra light

Hi together,

Ive bought myself following LED strip: link -

Please lets dont start arguing about the product itself etc... Im mainly using it for security reasons, since in my area it gets really foggy during winter I wanted an extra light, which I think works pretty good like this.

My main issue at the moment is, that I cant find anywhere the wiring diagramm of the rear lights. Im quite new to the saab WIS and it gives me a headache... i cant find anything there with the same names.
e.g.: this is the connector for the rearlight including blinker:


nothing is explained what is +, what is GND, what is the blinker etc....
with the wiring diagramm i couldnt find any of the connectors of 27RL :



please help on the following steps, which come from the suppliers guideline:

(1) Red wire: connect to 12V+
where do i take the +12V from the rear? is there actually a direct line there? otherwise i would connect it to the +12V of the rearlights, so it gets activated only when i turn the headlights on.

(2) Black wire: connect to 12V-
shouldnt be a problem. any suggestions where it would be the best though?

(3) Green wire: connect to ILLUM
need the +12V signal from the rearlights. which of the connectors 1-4 is it on 27RL?

(4) Yellow wire: connect to left/right turn signal
need the +12V signal from the blinker. which of the connectors 1-4 is it on 27RL? same for right blinker.

(5) White wire: connect to reverse wire
need the +12V signal from the rearlights. which of the connectors 1-4 is it on 27RL?

(6) Brown wire: connect to brake wire
need the +12V signal from the rearlights. which of the connectors 1-4 is it on 27RL?


thanks a lot in advance for your help! really frustrated my the whole afternoon this issue...


best regards
