Help!--replacing speedometer/odometer

[Jo-Ski]

Hi, folks--

Working with a good auto mechanic, we are trying to replace our speedometer/odometer. We believe the original instrument was a Teleflex (because we determined the rest of the original dashboard instruments are that) that was at some point replaced by a Motorola instrument, which no longer works.

Now we have gone back to a Teleflex, butthe devicecame with no documentation whatsoever for hook-up, calibrating, etc. (I am not mentioning dealer names just yet).We were told by the dealer that it's a "trial-by-error" thing. The mechanic figured out the basic hook-up. However,with regard to setting the 9 calibrating switches on the device, after a couple of hours of going around and around the block with the mechanic stopping and making adjustment after adjustment (e.g., because the devicewas reading 70mph whenthe coach was going 20 mph, for example), we realized the maddening absurdity of the situation because the number of combinations of those 9 switches is endless. Because we are good customers, the mechanic kindly agreed not to charge us for all this needless waste of time.

We are hoping someone out there might might know the exact combination of those 9 switches specifically for an '83 FC 35' RB Blue Bird Wanderlodge.

Thanks so much in advance for any help!
