Speedo issue

[Z-train]

Is there a known issue with 85 720 speedo's?The truck my fried pick-up had the needle ffall off and a bone yard unit from a 93K truck was "stuck".Meaning the needle would stay where you moved it to.

Yes. Use a 1986 speedometer from a low-mileage truck.

There's a bone yard here with Datsun pickups?

[ggzilla]

For sure.

http://www.car-part.com lists a half dozen, if Ace don't have one.

The yard on Park st has a 86 truck.

Just picked up a 86 cluster.Is this a plug & play or does the head unit itself need to be swapped?

[datzenmike]

The complete cluster can be swapped.  Or you can keep yours and just swap the speedo. I sent one to California once to trade for a 4x4 oil pressure gauge that reads PSI. Some clusters have the optional clock and tach in them.

Cool.Just realized this is a 4X4 dash.THe wire/plug hanging out of the back is the 4X4 light....right?No such luck with the tach &gauges.

[datzenmike]

You can add them later if you find them. The ST model will likely have full gauges. If you find a tach you need to get the 2.2K ohm resister that goes in line with it.

 

The two wires on a plug hanging out the back is for the clock. The tach is part of the 10 pin connector and is already wired in (just need the resister)

This is a plain jane dash.No guage except temp.But it has a "plug tail" hanging out the bottom
