<< Hi everyone I have finally rewired the whole car with the exception of the
high beam switch. My 16 year old multimeter finally died on me. I have the
switch situated with the three connections facing up. Can anyone tell me
the order in which the wires get plugged in? Also the new wiring harness I
purchased from Moss only has one ground connector available for the four
smaller gauges. The manual only shows the fuel and temperature gauges being
grounded. This may be a dumb question but do I need to ground all four in
order to get all the gauge lights to work? Did earlier TR4s not come with
gauge lights or do the ammeter and oil pressure gauges not get grounded?

Hi David
The center post should be the blue wire, I don't think the other 2 matter
which side they're on. My TR4 has a black wire with a number of ring
connectors spaced along it which is to ground the small gauges. You don't get
this with a new harness. Easy to make if you don't have one. If you have a
wood dash, the lights won't work (and maybe other things) without it.
