Our records on this one are thin beyond the identification itself, so we can't speak to specific fitment details, mounting position, or wiring configuration from what's on file. If you're trying to match this to a particular bike, bring in your old switch or the part number from your parts book and we'll confirm before you buy.
Given how many manufacturers used Lucas switchgear in this period, cross-checking against your bike's wiring diagram is worth doing before you commit.
