Now then, sometime ago on Mogtalk we were chewing the fat about Roadster relays & relays in general. I managed to take this photo

of my 05 Roadster installation, and Colin Jones5857 did the impossible

and came up with the functions.
So L to R it's:
Cooling Fan (High Speed)
Cooling Fan (Low Speed)
Ignition ECU
Fuel Pump
Start
The big one it turns out is wiper delay.
The relays must be fitted with a diode. They are behind the speedo & revcounter and the photo was taken with the drivers door wide open looking up above the steering cowl.
