Installing Cruise Control on a 172

#1
Hi all,

I never really thought it was easily done until I took my control panel off and realised I had 2 unused plugs behind it.

How hard and what work is involved to install cruise on my car and what do I need?

So far I'm aware I need a steering wheel with cruise control buttons, the obvious cruise button panel and something about a clutch switch?

What are those unused switches for behind my switch panel?

Any information will be helpful.

The most expensive item is the squib (clock spring) behind the steering wheel. It needs to have an extra connection for the cc buttons.

Buy new or get one from a wrecked 182.

The cc buttons can be fitted to a 172 steering wheel. The airbag needs to have two small pieces cut out for the buttons to fit.

The unused sockets are the halogen headlight level (not used on a car with xenon lights) and the cc switch.

@Vaughan Mines an early 172 without ESP. I bought a panel with the ESP button thinking it would be as simple as plugging it in but nothing happens.

Any ideas?
The early 172s don’t have ESP so there will not be wiring for the ESP switch. There should be a plug for the cruise control. You need a cruise control switch. Plug the switch in, turn the ignition n and off a couple of times and the dash should display SET - - - -.

If it doesn’t shot SET then the cpu might not have the ability for cruise, but I believe all 172s do (except Phase 1s).

So I don't need a steering wheel with the buttons? Or a clutch switch? Mine has ESP

The wires and plugs are there for the cruise and the ESP. Not that I really need ESP, it would just be nice to have the button working. I'll try and pick up a panel with just the dash light dimmer switch.

Early 172s without ESP don’t have the wiring. That extra socket is probably for the halogen headlight level control.

ESP cannot be retrofitted without a lot of effort, the ECU is different plus there is a yaw sensor and different squib with steering wheel angle sensor too. None of the wiring for those us there.

Ah. It was just the fact that one of the white plugs fitted into the ESP switch and the other ones didn't that got me wondering. There's 4 plugs in there, two white ones and two smaller black ones. I know naff all about electrics though. Cheers for clearing it up.
