Silly-ass question about instrument cluster wiring...
Do the normal cluster and the HD gauge cluster use the same wiring harness??? Is the HD tach cable-driven or is it electric? If electric, is it a transistorized tach? I'm buying an HD cluster from a forum member, and thought about the wiring as an aside. So, are there any changes I need to consider when changing out clusters, in terms of wiring?

I would think that the wiring is the same for the gauges and the tach uses an extra harness. Just can't see a totally different harness for the H D Gauge option. Just my guess.

Patrick,
The wiring is indeed the same,with added wires for the tach. There were cable driven tachs in Med.Duty trucks,but most were electric and require a sender like a Sun eb9a or the like.

I believe the tachs were different depending on the year. I know the early trucks required a tach sender but not sure about 69-71.

yes - the earlier tachs are different but all years used a sender.soopernaut wrote:I believe the tachs were different depending on the year. I know the early trucks required a tach sender but not sure about 69-71.
Patrick - i converted mine to a one wire tach using RedLine Gauge works. the senders are usually full of corrosion or don't work very well.
i have had my butt in a few HPP trucks and the only ones that worked were the converted ones like mine.
