Wiring issue TS 15/150

[ivor]

Hi all. I have rebuilt a TS125, (with a 150 top end) and am just finishing off. However I have found that there is one too many wires versus connectors on the speedo. It would seem that the charging light and indicator light share the same bulb, so do I simply use a 'piggyback' spade connector and connect the two together ?
Cheers, Tony.
