quicky to be sure.

thin fitting to live -  fatter fitting to negative

Are they from a Boyer kit ?
If they are then they should have + and - marked near the terminals.
Can you also post a pic of them mounted as I'm not really happy with how I've mounted mine.

Yoshi823:
If there's no +ve or -ve marking, it dosn't really matter, as the primary/input circuit isn't polarity conscious. One side will have the +12v standing voltage, the other will be the switched input from the contact breakers.

So the spade connectors are the low tension input, the output to the spark plugs is for the fatter connector.

Tim, I was refering to the HT leads attaching to the coils.

fatter earthed cable end to negative output - thin live HT end fiitting to live output from the coils or does it not matter a toot ?

Bryanj:
As its a Wasted Spark system with both plugs sparking together it dont matter
