Rostra 250-3742 Universal Left-Hand Mount Open Circuit Cruise Control Switch

The left mount circuit is very easy to mount. The use is fiendly and the documentation is very good. I suggest to buy this article to everyone. Many thanks

Not hard to understand the installation instructions and good phone help. It took about 3 hours to complete the whole job, (control module and control switch) under the hood and inside the car. Now that I know how to do it, an hour would be enough to get it done. Works good and helps me get better gas mileage.

Recieved the unit, would not turn on. Tried to trouble shoot with provided instructions. Unit does not recieve power, check with a multimeter. Everything else shows 12v except the controller itself. Wire going into the unit has 12v power. Does not work. Waste of money. Customer service is non existent.

Like others have said the on off button is touchy. Overall it fits the bill and works well. Seems to be well made

I had the control cruise control including the column mount installed by a mechanic. I think he had some difficulity getting it all done, but it works like a charm and holds a very steady speed. Overall, it works as well as the factory systems in my other cars.

Works fine, but if you need the T-bar adapter Rostra fleeces you for $30 extra for that tiny piece of metal. (A search online failed to find cheaper sellers of that adapter, no doubt Rostra doesn't sell it wholesale for much less).

Having read the reviews, good and bad, I chose to give it a try. With the exception of the wire colors differing on my 91 Honda Civic DX from the instructions and I might add the wiring diagrams in the various manuals and other sources the install went perfectly. Evidently, Honda wires each Civic differently? Used the loop throttle attachment so no additional brackets to buy or fabricate. Switched the gain two times to get it right and my 2400 mile trip was a pleasure. Unit did not miss a beat. The only connection to the distributor was the tach feed so nothing to cause a problem with the distributor.

Unobstrusive, easy to install on the steering column with a drill, it's almost as effective as factory installed rather then aftermarket. Used on 2003 Toyota Matrix RX and fits perfectly.
