Hi crew, thanks for chiming in and pointing me to the lectric connector, though the water just got a little muddier for me
The lectric connector is opaque white and of a style where the wire is 'in line' with the sender pin axis, whereas the classic one is black and has the wire at right angles to the pin axis.
It seems that neither of these is correct, as it should be translucent white or clear and at right angles?
If this is the case, then the classic one is the best compromise.
Cheers,
Rob
edit: In fact the lectric one almost looks like it's porcelain and immediately above it is kit 34620 which is very similar to classic's kit, though the lectric one has the eyelet [bolt -on type sender connector] already terminated to the wire and the others loose.
Even more perplexing is that lectric quotes that kit as being for everything
except 68 with gauges!
