Hi Everyone.
We are in the middle of the process of swaping out a DCT from a 135i E82 N55 car for a Manual Gearbox.
Trying to figure out the wiring process to make it work. Does anyone have any guidance? I can't find anything online about this method on N55 E series engines.

Thanks in advance,

Bump. Anyone?
@LMB335is do you know what wiring needs to be done?
I know that the CAS, FRM and DME need to receive signals, but can't find anywhere what pins are.

Shit, I think other than the clutch switch wiring, that's it as far as wiring goes AFAIK. 2TC needs to be removed from the VO and default code everything with the new VO. All the modules are the same, just coded differently

We are getting everything coded today.
Just to let everyone know. there are 4 things to be wired from the new clutch switch:

1 ground
1 wire to CAS for clutch remote signal
1 wire to DME for clutch remote signal
1 wire to FRM (that goes to 2 different FRM pins for reverse light switch)

There are some variants on which pins you are getting compared from a regular ZF6 to Manual Swap.

CAS PIN 41 was occupied by a signal wire from the auto trans. Depin this wire, wrap in electrical tape, etc. The new wire will require a new pin terminal
CAS PIN 2 requires a new pin terminal
DME PIN 31 requires a new pin terminal from connector X60001
FRM PIN 47 requires a new pin terminal

After this, Remove VO Code: "2TC" and Code all modules.

About to swap my manual to DCT. I wont need to remove the clutch switch wiring that you needed to add. Do you think I need to change anything else to make the DTC work in the DME/CAS?FRM? I have the DCT harness.

I also see the clock spring and indicator stalk in that "swap kit" picture. Is that indicator setup needed for the paddles? I did NOT manage to save that from the donor car... I sold it.
