Try and get someone to help, so they can press the switch etc when you put a finger on each relay(in turn) to see which one clicks, the fact that something clicks says the wiring between dip/main stalk is ok, do these ones have dim dip ?, if they do could as said be that, just try with igntion on as this sends a feed to dimp dip module when in sidelight only mode on switch if ignition is on.
