On 1150 RTPs a relay is sinked to ground thru pin 17 of the motronic ma 2.4.
The relay contacts can be used to automatically and optimally operate the fan.
If you need a contact pin to do this mod, PM me and I'll mail you one.
Interesting. What about the 1200?
Here is a picture of what I've got - SPAL fan - around 120cfm - lighted LED switch is by the speedo. This is bolted to the upper crash bar on a 1200GSA. The SPAL is waterproof etc. (got it on eBay ~$50) but I can only fit one in there. Since I've installed it I really haven't had to use it, so I can't say just how effective it is. I know it works though...
