Can we do this? (aka The DIY Cruise Control Thread)

[Paulee]

Hey guys. Got myself an 09 Yaris recently and want to add the cruise. Ordered the OEM stalk from China and was wondering if I will need a clutch switch too. I know the guide says I do but shouldn't the car already have one? havent tried starting it without pressing the clutch in (force of habit) but the switch should prevent the car from rolling forward on the starter no?

apologize in advance if this was already covered elsewhere.

It does have a switch that tells the car you are pressing the clutch all the way in. It is not same switch that you would need to install that tells the car your clutch is all the way out.

the two switches would be on opposite side of clutch. If clutch is fully engaged the one switch would be used. If clutch is not engaged at all, other switch would be used. If clutch is halfway between then both switch would not be used.

thanks. since posting I went through all the pages and some associated links. Think I have a good grip on what to do. just waiting for my stalk to arrive. might skip the clutch switch for now and drive around it. sounds like I dont have to dig under the dash and engine bay if I do save it for never.

For me, the wiring was tied down by wire tie just above the clutch.. Cut the wire tie and pull wiring down and there it is ready to plug into the switch.

By my logic, If you don't have switch installed, the car will be thinking the clutch is not engaged and therefore cruise control won't turn on.

If I am wrong and it works, just be careful cause if you have CC engaged and you press down on clutch, the engine will rev up quickly and could damage engine if you leave it revving long enough.
