Has anyone added a cruise control kit to their 240? If so which one and how tricky was it?
timbo
I know vince harmer attempted to fit a factory kit to one of our customers cars but wasnt happy with the overall function and removed it
Ex850R
I wonder if one off another car could work cheaply?
The old Cressida had a good mechanical system , the sensors though....

I have a factory cruise setup from an 84 240 & had planned to fit it to the turbo'd 88 240 wagon, got a feeling things might need adapting like the throttle spool & that there's no provision for a clutch cutout switch which I can live with. Will post results when I do it.

740 system can be used. Just need to find a 240 stalk and if k-jet it needs the specific spool and bracket.

Clutch cutout switch would be easy enough....
Just tap it into the brake cutout input, use a diode to stop it feeding back into the brake light circuit...

My personal opinion is that most aftermarket kits are a bit cheap and nasty in terms of quality, yet often not cheap to buy.
The Dana cruise control that was offered as an accessory from new on 240's from around '80-'85 tends to be a bit unreliable, and apparently it tends to struggle to hold speed when going uphill, even when working properly, so I'd avoid that.
The vacuum operated system on the 700 series is pretty reliable and works well, the only disadvantage they have (which the Dana system also has) is the lack of a decel function on the stalk. If you want to set a lower speed, you have to disengage it, then set it again at the desired lower speed. This is just because of the age of the systems, many didn't have that function until the '90's.
Here's what I'm going to do, to add cruise to my '77 245L project car:
I'm going to use a complete 700 series system, ie: ECU, vac pump, vac actuator, brake switch, and clutch switch.
240 stalk switch from the Dana system, which is electrically identical to the 700 switch, and uses the same wiring connector.
I'll make my own wiring harness from scratch.
Throttle spool to accept the cruise control cable from the vac actuator, to suit the K-Jet manifold, I bought this from the US, cost me about $60 from memory.
One custom part needs to be made, a small bracket to mount the vac actuator to the K-Jet manifold. This is fairly straightforward, there are a couple of holes on the side of the manifold so I'm just going to weld up a small steel bracket and bolt it to those holes. This will interfere with the vac fitting for the heater controls, so that will be plugged, and I'll use another location for the vac fitting.
I've got all the required parts ready to go, but it could be a while yet before I'm ready to fit it all up.
I'll be using an '86+ diff in the car with speedo sensor, so the system will get it's speed signal from that sensor, but if you have an earlier car, the Dana system uses a small impulse coil that attaches to the back of the mechanical speedo, so you can fit one of these if fitting a 700 system to a pre '86 240.
I think I have a spare 240 cruise stalk available if anyone needs one.

Sounds like a lot of work, but definitely worth it for the end result. Has anyone had much experience with the Command Cruise Control units that a lot of places recommend?

i bought a factory cc set up out of america had to fab up some mounts for the peddle switches but other than that it wasnt difficult there are a few differnt kinds one works and pulls the thottle in the engine bay the other pulls the pedel (the one i got). however it only worked for 20 odd minutes and then the brains for the cc fried itself

I have come into possession of a '90ish cruise control kit for a 240. I'm going to try and set up Nina's '81 244 with it. We're running LH-2.4, so speed signal is at least easy, but I think there's a few other challenges. I don't have the loom for the vacuum pump or the main connector as those I think were part of the factory harness for newer models only.
I'm also not sure if Nina's 244 will have the right accelerator pedal for the actuator rod to connect to.
Vee_Que
The rod connects to the manifold.. I have a spare 740 loom if you need to see the wiring.order. I also wired in 960 cruise onto m my 760.
jamesinc
Maybe this is a different style? This one mounts under the dash to the accelerator pedal.
From my other cruise control thread:
Angus242164;62858 wroteIn about 1992 there was a vacuum operated system similar to the 700/900 system, I've never seen one in Australia, they got it in the US but it's not very common there I don't think.
I think this is actually what I have. It's for a 240 and it has a vacuum pump.
Angus242164
Duncan was telling me about a system on late US 240's with an under dash actuator acting on the pedal or cable, I've never seen one before, but was apparently the norm on US 240's for the last couple of years of production, it sounds like this is what you have.
jamesinc
Yeah I'm pretty sure this came from overseas originally. Okay cool, well I will do a write-up on installing it then. I found some good photos online of another install. It looks like I'll just need to make a bracket to hold the actuator, and add a little tab with a ball for the actuator to connect to. The main thing I'm missing is some plugs to fit the vacuum pump, which is a 3-pin D shaped connector. Number 5 in this diagram:

I should have a connector like that among all my junk, I can take a look if you like.
jamesinc
That'd be pretty great!
Philia_Bear
You should hace asked for one when you were here last night
I have a pile of then from all the removed wiring harneses
They even will have pig tails with several feet of wire
jamesinc
Derp. I'll swing by in a week or so with some more pork buns.

MMMMmmmmm pork buns...........
Hey Paul
I bought a second hand Momo steering wheel with just 2 buttons on the spokes.
One labelled for "on" and the other labelled "Set" ,in anticipation of adding cruise control.
I was hoping it negate the need for the 24o indicator stalk controls also it should look good and be more functional.
The wiring shouldn't be a big deal.
Was I right in thinking this ? ...
I look forward to following this thread.
