[TR] Another TR4 wiring question

[Andrew Uprichard]

Thanks as always, Randall.  To complicate things even more, the diagram
shows 8 lamps, but there are just 2 red/white wires running to the center
cluster and 2 coming off the steering column part of the harness (presumably
for the large gauges).

So I guess as often happens it is a mongrel car with a postmarket harness
and a generic wiring diagram.

I just bought a 1959 TR3 with a TR4 engine, a pressed-on ring gear and early
starter, a one-piece steering column, early carbs with the banjo fittings
and TR2 seats !  If only these cars could  talk !

I'm not certain offhand about the early "curved glass" tach & speedo for
TR4; but the later "flat glass" only had one lamp each.  TR2-3 did have two
lamps each, though.

And early TR4 (like TR2-3) only used two bulbs for the 4 gauges in the
center panel.  I don't recall offhand about the "flat glass" gauges, but I
think they were similar.  At any rate, the owner's manual I have is 6th
edition and shows the ZS carbs (which came in around CT21470E), so it should
be for cars with the flat glass gauges.

FWIW, both the workshop manual and owner's manual (that I have handy) only
show 4 bulbs powered from the dash control.  Two are identified as "Ammeter
and gauges", plus "Tachometer" and "Speedometer".

So my guess is that Dan Masters just got that point wrong (at least for
early TR4); and lost interest before it got caught.

If anyone is interested, you can download the TR4 owner's manual (6th ed)
