ACC retrofit: wiring problem.

[fin-vw]

Hi,
Could someone tell me please
Transporter t6 2.0tdi 110kw 2017.
where I connect J428 (acc unit) pin numbers 2 (can high) and 3 (can low)?
I have pulled already the wires inside the cabin:
-Pin1 -> ground.
-Pin8->fusebox slot37.

i can't find the j788 relay. or the colors are in a different wiring diagram.

Can I connect somewhere else?

Coding advice is also welcome.
->search tell me that:
bcm 09 ->byte 5 ->change 60

probably something else is needed too.
I using vcds and factory odis at work.

I would appreciate your help.

You can connect to the PDC CAN-BUS wiring directly. If you are not concerned about CAN-BUS network safety then you could consider ignoring separation relay.

Assuming that you have CCS via MFSW,
coding wise you need to apply the following:

ECU 01


ABS 03

probably something else is needed too.

Matching radar with your Instrument Cluster or disabling CP altogether.
Plus uploading appropriate SWAP to match your gearbox type and ACC max speed.
