Audiovox CCS100 Universal Vacuum Cruise Control

The unit works great - I installed it on my work car, a 97 kia sephia, 5spd manual tranny. I didn't hook up the speed sensor, just the tach wire (on my POS it's the yellow with white stripe going into the back of the instrument cluster). I set the pulse count to 5000 PPM and it seems to hold within 1MPH under most circumstances. I have a 45 mile rural commute, and this thing has really made it a lot easier. It took me a little under 4 hours to do a quality install.

If you don't have a fairly firm grasp on electrical schematics or bracket building, don't try this yourself. On an older car with a coil that is outside the distributor, a tach feed is as easy as hooking to the negative side of the primary. On newer cars with the coil built into the distributor, or engines with multiple coils, it can be tricky to find a tach feed. To find a tach feed on my POS, I spent some time looking at schematics to find one under the dash. I got away with just hooking up a tach feed because with a manual transmission car, the engine RPM is a linear function of ground speed - or - the engine will turn a given RPM for a given MPH.

If you have an auto tranny car, you'll have to hook into your Vehicle Speed Sensor, or install the included magnet kit. Years ago, I installed a magnet kit on the driveshaft of an old Volvo with an auto tranny, and it gave me nothing but headaches. I wouldn't recommend this to anyone.

Long story short - this isn't a quick & easy thing to install, but if you install it correctly, it does seem to be a good little unit, and Amazon had the best price I could find anywhere.

Audiovox CCS100 Universal Vacuum Cruise Control would recamend this add-on. fairly easy to install but, wiring diagrams for ford are a little iffy. have used this product twice. tom o.

I have had this product over a month and still have not successfully installed it. There is no access to wiring diagrams and the instructions are very unclear as to what wires to connect. I installes an auto start system on this vehical. so I know with proper instructions I should be able to install this...

I just finished installation on a 1971 Impala, 350 V8 and automatic. While a little intimidating when starting, it seemed that instructions may have originally been written for an car like this, because I had no problem. Perhaps messing with digital controls makes it harder for others, but it was all simple mechanical and electrical connections on a car this old.

I didn't use most of the hardware, just the servo, the control switch and only one magnet required. A little troubling to get to the end of the job and have so much left-over hardware, but they seemed prepared for any eventuality.

Only required the ball chain and a couple of connectors to make throttle connection, it was the easiest part of installation. There is a bracket next to the coil that seems intended to accommodate the servo cable. If you have a Rochester 2bbl carb, it's a simple matter of popping off the snap-on throttle cable, slipping a ring connector at the end of the ball chain onto the carb, then pop the throttle cable back on. About 5 minutes to get that done.

I thought directions were clear enough, except perhaps on dip switch settings. However, help desk had the answers. My biggest difficulty was getting to places under the dashboard that GM in 1971 didn't think a consumer would ever need access. Not everyone needs to install all components (servo, control switch and magnet sensor), so each installation handled separately, which caused a little frustration because installing all three components required bouncing from one instruction sheet to another.

For this type car, it's hard to get it high enough with a jack to get magnet and sensor installed. I got frustrated trying to work in limited space, but fortunately had access to a military auto hobby shop. Once on the lift, had magnet and sensor installed in about 30 minutes.

Installed this unit on a Valkyrie motorcycle. No vacuum canister required, as the vacuum from 5 of the 6 cylinders is strong enough for the servo. Audiovox certainly provides enough pieces in the box to handle whatever your mounting requirements are (you don't use them all, so there are lots of extra parts left over). That being said, there's quite a bit of work, including some innovative thinking and some irreversible steps, so I would not recommend installation by someone is isn't mechanically inclined. As for its performance . . . the accuracy is very good to about +/- 2 mph. All in all, I'm very pleased with the system and, most likely, will install one on my other bike, before too long.
