I have seen some post on here about aftermarket cruise control. Like the Rostra cruise control, Was this a option in any vehicle or just aftermarket installs. Heading to pull a part tomorrow and would like to look for one. |

Just for clarification, Cruise control was NEVER a factory option on ANY Metro. But there is ONE that looks that way.... ![]() Rostra cruise control modules, are universal control units. Finding a universal one installed is a little far and few in between. But it gets a little weird over the past 5-10 years. Some manufacturers, started using Rostra units as the OEM, factory installed option. It's cheaper for them to buy the universal units, then it is to make there own. What does this mean for us? Well if you can find one, it means that there are 100's of units out there that can be adapted VERY easily to any car. The bad is know which cars got them. ![]() What your normally looking for is a medium-sized waterproof black or grey box approximately 4"x4"x6" that is located *usually* within about 12" of the accelerator pedal. It will say Rostra on the outside. ![]() It may have an OEM connector on the end of it attaching to the pedal. Most have about 3-5" of wire coming out of it until you get to a large connector about 3" across. Just get as much of the wiring harness as you can. The only thing you may not want to grab is the OEM style set/resume/on switches. You don't need them; you can make your own. I want to say the last one I got was from a 2005ish Suzuki Something or Another. As it comes from the junkyard, it will be programed for the car it can out of, however it is EASILY reprogrammed using the DIP switches located on the circuit board inside the box. I have the user manual somewhere.... ![]() Adding it to your Metro is up to you. There are no real guides or how-to's just because there are only a couple of us that have adapter in Cruise. This one, is NOT for the faint of heart. But when it's done....

Thanks stiffchezze. I knew it wasn't a factory option but sure do miss it on a very long drive. I'll walk the yard and see what I can find. I already bookmarked a couple how to install it. I won't have a problem with the install i don't think. I don't mind wiring stuff up. Besides I have a FSM I can look up the wiring in. |

Could you wire a 91 5speed with cruise control? |

You could wire a lawnmower with cruise control if you were dedicated enough! Yes, you can. Brake light, VSS, and RPM are the only signals you get from your Metro. Everything else is all new wiring.

One of the farms I used to work on had a huge International tractor that has cruise control

Factory stick shift cars have a clutch switch so the engine doesn't see the rev limiter. |

What exactly does that mean? |

If you disengage the clutch while using cruise control, the engine rpm can increase rapidly. Factory installed cruise systems have a brake switch and a clutch switch to disengage the cruise. |

The Rostra units have a wire coming from the ignition coil to "see" the RPM's. A sudden increase of RPM's (300 I think) causes the unit to cut off. Also it HAS to be wired to the brake switch in order to work. You could fool it, but it's MUCH easier just to hook it up right. |

![]() Just to let you know, the Rostra units are self contained. The box, the wire, and the cable out the side, is the entire unit. There were some old units from other manufacturers that had multiple pieces.
Some might disagree with me, but IMHO: Considering this is a unit that controls your car, and that you have to make a new harness that takes in inputs from an existing harness, I would put this at about an 8 on a 10 point scale. Also you have to make your own adapter to connect to your accelerator. I would not use this as a jumping off point to learn how to wire a car. |
