DIY Z4 cruise control stalk with ZCP steering wheel

[Obioban]

You can reenable cruise control on a CSL DME, so maybe you can do the same on a ZCP. Might have to route some wires though.

Won't even need a DME tweak :P

Only if you retrofit a CSL/ZCP MK60 DSC module.

I did this last year on a non CSL/ZCP. I believe I had to wire it into a relay to convert the signal from ground to 12 or 12 to ground.

I have a ZCP and miss having cruise control on long drives. Would love to do this if it’s confirmed that ZCPs can have this working properly.

Did you ever try this? I have a ZCP and want to do this but I'm not sure if the wiring is the same.

If you don't like steering wheel buttons, this will completely remove it:

Unfortunately, no. Been so busy with the silver car that all blue car projects have been put on the back burner.

BMW sells a kit with the wires to enable cruise on an e46 that didn’t come with it, it works the same for a ZCP car.

The part is 61120016012

It does work on ZCP, 2003+. My 05 ZCP came with the 'normal' steering wheel controls, with cruise functional. I switched back to a ZCP upper trim by just swapping one wire in the green connector on the bottom of the steering wheel. The Previous Owner had the Track Mode button pinned over to a E39 M5 wiper stalk button, like Obioban showed above.

I'm going to replicate this mod, as I want my cruise control!!

As long as your ZCP all the cruise control wires (See BMW part 61120016012) and it's functional with the multifunction steering wheel, you should be able to convert back to a ZCP wheel and use the cruise stalk without issue. That is the setup I have in my car.

I just did this over the weekend, THANK YOU for this write up!

if you want to tap into the two wires without cutting, I recommend these…very solid connection.

I did have to trim the bottom inside the lower cover AND the bottom of the the stalk base to get the clearance needed, but I’m not worried about it.

I also just removed the foam/metal piece altogether by cutting the plastic rivets they are popped into, made this a much shorter ordeal.

Looks fantastic, nicely done!

Excellent the info I was looking for!

Will this work if i want to only add the cruise control stalk and still keep my MTM button working? Or do you lose the MTM button by adding cruise control?

This will keep your MTM button working. You need to use the retrofit kit, BMW part number 61120016012, but then you can follow this guide for everything else.
