DIY Z4 cruise control stalk with ZCP steering wheel

[silbergrau137]

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.

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.

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

Great write up and excellent find. FYI the part number for the "no-button" upper steering wheel trim is: 61 31 8 383 366

This is awesome! I really missed my e36 CC stalk. Nowadays I don't even use CC, but this is still really cool. And obviously the perfect way to do it, they even have the same (as my '94 e36 was) in my 2012 E82.

I'd think you could wire the IO button on the steering wheel to do the same thing as the button on the center console though, yeah? Both are just buttons.

Yeah, but the pin doesn’t do anything unless it’s an 817.3.

I had the button wired up for a long while with no 817.3– didn’t do anything. No change in wiring, 817.3 swapped in, it works.

^I’ve got that as well on my ZCP car ... came that way from the PO since he also added the multifunction controls back in. Very tempted to go back to a fuzzy wheel and single MTM button. Cruise control functionality mod in this thread is excellent, but pretty sure I personally have used CC like twice ever.

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

You could combine that with a e39 high intensity washer stalk to still be able to activate MTM and have no buttons at all



(I have that for MTM activation, but I like the steering wheel controls, so not doing button delete)_

This is very cool. Can the zcp button be set up to turn the traction on/off on a non-zcp car?

Thats great work! I love cruise control, the lack of it actually kept me from buying a ZCP. Sounds small but its a must have for me. Way to solve a problem

I think so, although I haven't tried yet. Right now that button does nothing. I assume since the button on the center console is just a button I can wire it to the steering wheel IO button to do the same thing. Once I figure it out I'll be sure to post it here.
