VSS buffer location

[Chipsbyal at aol.com]

All of the CK trucks from 88 on up have an electric speedo. They all have a 
40 tooth reluctor at the trans. The early models had the buffer built in the 
cluster. It is calibrated with a jumper. The newer trucks (not sure what 
year) used a DRAC, which in turn fed the cluster, PCM/ECM, cruise and RWAL 
brakes. This is a little white box beneath the glove compartment. These can 
be modified as well, just need to do some soldering.
