Tailgate power latch retrofit Bcm pin30

[Stevemcc]

Hi all, trying to finish t6 tailgate power latch retrofit
Am stuck with one wire the blue what goes to pin 30 at the Bcm
I have checked Bcm and already have a blue wire in it , so question is where is that wire going (what route) is it taking and could I join in somewhere in the van

Hope am making sense and thanks for any help and info

I didn't bother tapping into any of the existing wiring. I simply bought a momentary switch and wired it directly onto the tailgate actuator.

Where does the other end of the wire go ?
(i dont have wiring diagrams in front of me)

It goes from control unit in n/s rear quarter panel above n/s rear wheel arch to under passenger seat, I have fitted new white t17j plug ( I think pin 1) is the location. Just stuck from here to Bcm pin 30

No cables need to go to the bcm
Where does the other end of this cable go ?

That cable is the switched negative return from the tailgate to the bcm so is present on all vehicles
You just need two wires from terminals 6 & 8 on the control module and run into the roof above the rear quarter and just cut and join it there

I think it’s pin 9 on the multiplug above the control module

Did you check under the seat at white 17pin plug to see if theres blue wire at pin 1? Youre probably prewired from factory for it but not to the tailgate from there. That wire doesnt seem to be feeding anything else other than latching module.

Scrap that just saw you added the plug

My pin 9 in roof n/s has brown/blue , I have connected terminal 8 also brown/blue from control unit to that

 

[Pauly]

The cable needs to be cut then terminals 6 and 8 connected to each side of the cut

 

[stan-the-man]

Looks like in T6 the pin 30 goes directly to tailgate lock where if there’s latching it goes to latching module first and then out to lock so basically running through it so important part is to connect the right ends to pin 6 and 8. So from pin 9 on tailgate plug to pin 6 on latching module and from pin 8 on latching module back to pin 9 on tailgate plug
