Aftermarket cruise control

I am missing the "enclosed reference manual" for the audio box ccs-100 cruise control. Has anyone installed this and happen to have the manual? Or where to locate the stupid thing? I have to set the dip switches to rotations of the driveshaft.

Thanks! But I don't have a Yamaha Roadstar!!!! Haha! I have found and downloaded the installation manual but I am unable to locate the reference manual to find out how many pulses per minute to set the system to so it reads properly. From what I gather this is how many times will the magnets I mount on the driveshaft pass in front of the sensor each minute to let the system maintain speed. I did find one reference manual but it didn't list the P30 on the list.

Oops, guess I missed the Yamaha Roadmaster part!

It sounds like you're looking for PPM (pules per mile). Looking at the instructions it sounds like there is one magnet on the drive shaft which means for every rotation of the drive shaft there is one pulse sent to the cruise control module.

Your diff ratio should be 4.56:1. I'm assuming your tire size is 8R 19.5 so the revs per mile for that tire are 621/revs per mile. 4.56 x 621 = 2,831 drive shaft turns per mile or PPM = 2,831.

The dip switch settings provide for 2,000 or 4,000, 5,000 or 8,000 which aren't really close to what your actual PPM is.

Looking at the CCS-100 manual it says you can also use the tach signal as a speed reference. I've actually used an aftermarket crusie control that used the tach signal and it worked just fine with one exception. If your transmission craps out then the cruise control will start to rev the engine as it tries to keep your speed up. Net result for me was an over revved engine after the transmission blew up. So I guess I wouldn't recommend using the tach as a speed signal!

Another choice is to use a signal generator. This is what the normal Classic motorhome used as a speed reference for the cruise control. GM used speedometers that were expecting 1,000 revs per mile from the speedometer cable. So installing this signal generator creates 8,000 revs per mile that can be sent to the cruise control module.

Wow! That is math I could never wrap my head around! Amazing! Thanks!
I'm gonna try and tackle the install maybe sometime this week. Then off to get the u-joints changed. Got a nasty vibration up to 60mph and they are the only other thing I can figure is wrong. It also bangs pretty hard when I put it in gear. I had the front two changed already as they were terribly worn. I should have had all of them done at the same time.

There is no guarantee that my math is right! It would definitely behoove you to double check it

I would also suggest that you skip the magnets and just use the signal generator as it would be a lot less problematic in the long run.

Did you just buy the Audiovox cruise control?

If by signal generator you mean where the cable attaches to the tranny that port has fouled. The speedometer and cruise stopped working and I have taken it to a couple places and they say the back of the transmission would have to come off $$$$ because the gear has fallen inside . Or some such irritating thing. We put a drill on the cable and the speedometer works when that happens so I def know the problem is down there. I figure this was the cheapest way to get the cruise working as I am really tired of foot feeting it down the highway. I have a heavy foot and it takes a lot of effort to keep her at a reasonable speed.

It shouldn't be that expensive to work on the speedometer drive gear. If you remove the transmission extension housing it's right inside on the output shaft. I believe it's just sort of a light press fit onto the output shaft. There is some info about the TH400 speedometer gear in this thread.

The tail shaft extensions are removable without removing the transmission from the vehicle. You will have to drop the drive shaft and since you probably have the parking brake drum you will likely have to deal with that as well but that should be about it.
