HOWEVER, the factory cruise control is a VERY NICE unit, probably the nicest I've ever had the pleasure to use with a 4cyl vehicle. It's very smooth & holds a steady speed much better than any aftermarket unit I've ever tried in various other cars. It's also MUCH MUCH easier to install than an aftermarket unit, but only if you know what you are doing.

Some folks on this board helped me out a few months ago when I swapped in a unit from a 1993 940 wagon into my 1992 740.

The reason it's easier to add a factory unit is that all the wiring and mounting points are already in place in your car & all you have to do is add the right parts and plug them in. Here's what you can do:

Just find a junkyard with a 740 or 940, any year, and remove the following parts:

1. Turn signal stalk/cruise control switch

2. The tri-cable spool on the air intake (you have a dual-cable now)

3. The vacuum pump on the drivers side inner fender

4. The servo unit with cable that goes to the throttle actuator on the intake.

5. The brake switch under the kick panel and against the brake pedal

6. The two associated vacuum lines.

7. This is what people here helped me find: the computer control unit. It's under the kick panel and riveted to the inside of the fender where the drivers left foot would be. It may be up high, it may be lower depending on the model you are extracting it from. It's a box about two or three times the size of a typical volvo relay, with a single connector plugged into it with about 30 or so (just guessing) pins. It may say "made in Germany" on it, or have german writing on it. It may not. It is delicate. If you are unsure, look at the same spot in your car and you should be able to find the connector for it, but your car will not have that little box. That is the one you need. The box is delicate, be nice to it. You'll never be able to reinstall it just the way it was in the donor car 'cause it's just such a pain to deal with those rivets. Take your time and be patient in removing it from the donor car & you'll finally find a way to get it out. When you put it in your car, just find a location similar to where it was in the donor car and gently but securely fasten it upright.

Also, all the wiring is there, but it may be held rather out of view by cable ties. Sometimes its hard to find, but it IS there. Be patient and don't break anything or pull any other wires off their terminals or you'll be very unhappy.

If you dig through the archives you'll find other posts about how to correctly install the cruise control.

My last problem was with the brake switch. It has to be adjusted well or the cruise just won't function at all. When you remove the brake switch from the donor car, note exactly how far the brake pedal pressed the little plunger in when the pedal is not engauged. Try to make it go in that same amount when you put it in your car.

My total time of swap/installation was about 8 hours, because I had no idea what I was doing on the Volvo the first time, and because I was waiting for responses from this board. Now that I know what I'm doing, I could probably do it in less than an hour.

From someone with a LOT of experience with different cruise controls, take it from me -- the factory unit is WORTH IT!

You may find it is more expensive to get the used parts than to buy an aftermarket unit. Again, it's worth every penny.

Also, some folks who frequent this board sell all the parts as a kit ready to go into your car. Maybe they'll respond?
