The engine temp is sent to the Vapor gauge unit by a connection to the spark plug.
To accommodate the ring terminal that goes around the spark plug I'll have to remove the existing crush washer.
Not as easy as threading it off, but it's gone, nonetheless.
...the fit to the spark plug is nice...
...but the spark plug well is going to be a tight fit. Unsure of how this will work out, I'll just try cramming it down in there.
And you can see here, it didn't hold up too well to the abuse.
...and it looks like it will need to be extended...oh well, that's for another day.
