Module is pretty standard on all later model Hondas just look at the plug configuration, yet I believe they are all the same.
Any Honda model series CB, GL,CX, Goldwing from early 80's will work. These used to be dirt cheap but are getting a little more expensive as time goes on. They rarely fail, so buying used isn't an issue.
Here's a set for $35.00 US that will work for you. eBay item number:331772058275
