My search for micro-relays began with some instructions for converting an ST1300 to an electric windshield. It has a picture of the two types of Micro-ISO relays, as well as the seemingly identical "suspension" mounting sleeves.

Ron Ayers shows the two-way Micro-ISO relays on their ST1300 cowl microfiche. It's item five, part number 38502-MCS-G00, "RELAY (MICRO ISO 5P)".

For reference, his same relay is available from Cycle-Parts for $6.46. Ron Ayers, by comparison, is $6.15.

Also on this same microfiche page is item four, p/n 38306-MCA-000 "SUSPENSION", which is a sleeve intended to attach the relay to the cowl. These "suspensions" also make excellent waterproofing housings for simple switches, such as you might use for accessories on your motorcycle. Just cut a round hole in the end and fit it snugly around the switch body, and zip-tie the open end closely around the wires. Don't buy this one, though, because...

There is another, seemingly identical relay suspension available. But it's nearly half the price!

This second, cheaper relay suspension appears on the ST1300 wire harness microfiche as item nine. Also shown is item eight, 38501-MCS-G00 "RELAY (MICRO ISO 4P)". This is a four point relay, meaning that it can only close a single circuit, it cannot switch between two circuits. Since it's the same price, at $6.15, I can't see any reason not to buy the five-point relay!
