Hi Rob,

Yes, I was sure you had connected it too, although I tend to err on the side of more faith, estimating others' diligence.

I'm guessing your "add-a-lug" is for a .250 faston, and this is a .187, but it is gobs faster to get at the ECU connector than to pull the cluster again - that is why I offered the suggestion that would check the circuit back to the source. Also, the clue I offered about the VSS signal being necessary is worth checking.

Your instrument lights will probably die each time you bump the cluster; they are the newer halogen type, shockingly expensive, and extremely brittle when aged. FCP can provide you with the best prices.

I don't think these cars had any kind of adaptive electronics, but if they did, I guess it would be the LH 3.1 version.

Beginning with LH2.4, the fuel injection ECU is adaptive, although its memory is volatile compared with the Bendix (Regina) equivalent. All you need to do is remove fuse 6 or disconnect the battery for a second, and all modified fuel trim is lost. However, I don't know about specifically the shift point table - most likely because I didn't pay attention, not having any 5-speed cars.
