I found a tach cable for the Mitsubishi K3D that's in my HDT1000, so it's working. Price wasn't all that bad either:
Now I need to find a temperature gauge.
Looking at mine it appears that the connection at the sensor and gauge are both hardwired, so I'll need the whole thing.
Would the threads on the block for the sensor be some sort of industry standard? If so, that might make my search a bit easier.
I would need a gauge that fits in a 2" hole.
Anyone have any suggestions/sources?
