L is leading (lower)

T is for trailing (top)


L-lower
T-top

The spark plugs are marked just the the engine block is with T ands L's also the ignition coils are all marked as well with T1 or 2 and L1 or 2 so you can always know where the spark wires go, get a flash light and look down there, hope this is of help otherwise oh well

I believe the plugs are also marked "T" or "L", in addition to the number.
