Thanks. Can you tell me more about the supplimental harness?
The two spade connector rev counter I borrowed had one connector market + and the other was unmarked. I tried all the combinations of hooking it up I could think of:
+ to 12V, other to distributor
+ to distributor, other to 12V
coil to +, other to distributor
coil to -, other to distributior
Body earthed in all cases.
The action of the guage was always to ram at full speed over to max as soon as power was enabled (either through connection to battery or when ignition was turned on), or not to move at all.
The rev counter I still have is a 6000rpm red line one, and has one spade connector on the back, and one other connector that looks like a screw on clamp connector which is isolated from the guage body. I'll take photos some time. Ive never connected this second connection up to anything. My car is a 1963, but I dont know if its early or late in that year.
