From Australia so metric measurements
After receiving advice here I have purchased SGI-5E Universal Signal Interface Unit. The Instructions over abut 7 pages present as a little complex and I am unsure of the correct settings for the "output side" of the unit to my Volvo 240 electronic speedometer and I don't want to burn out either the Dakota unit or my speedometer unit.
Vehicle Information
Ford 5.0, C4 Transmission, Salisbury Differential - speed sensing comes from transmission - not diff as in std Volvo.
Diff Ration (t-shaft turns 2.7 times per wheel revolution 2.78
Ford C$ Top Gear Ratio 1.1
Tyre Circumference (mm) 1930
Tyre Revolutions per Kilometer 518
Ford Speedo Sensor Pulses per rotation of transmission output 8
Volvo Electronic Speedometer Information
Volvo Speedometer is marked on the face as a K24964 - It think this means that over a distance of 1 kilometre the speedometer reads 24964 pulses - but I am assuming this from what I have read.
I am unsure of which of the various options in the Dakota Digital instructions (there are seven different methods) to correctly wire from the unit to the wring into the speedometer unit.
I would appreciate any advice.
