Convertible top issue

[banzia]

Hi Guys
Got an issue with my 1999 boxster soft top.
Had it down the other day but it refused to close...
I managed to get it closed by removing relay and linking some of the connections. Seen this on youtube... So motor seems to be ok...

I checked the fuses which are fine.

I have checked nearly all the sensors that Im aware of. Doors micro switches. The micro switch in the roof clam. Its all looking like this very pricey relay..

Can anyone please list the sensors or switches in this system before I buy this part only to discover its something else..

regards
james

ps, I have opened up the relay and its quite a technical bit of kit for the era, not your average relay. I have no idea how to test it...
