I googled a # Derek had posted for this switch, and came up with a few hits for BMW's, Volkswagon, Citreon, etc.
Found it at the auto parts online for $16.76 US, ordered a couple for myself for my 99 ST2. The fan seems to be coming on later than I like. New +/- errror was listed at 3.4'c at 100'c, fiqure 2 sensors with some age on them maybe 10'c or more possible error. I'll change them and feel better, hoefully run cooler.
My fan isn't going on until 221'f, but the bike is running between 155-180'f [so far, just got it going 450 mi. ago]and I live in the desert.
0-280-130-026 Bosch not sure if this is the long or the short one.
