I just put one of those (same brand, bought from VA Mustang) in a 65 convertible project I've been working on. Be careful pushing the spade connectors on. They were very tight and the connector came off of the rivet on the constant voltage regulator. Of course this happened on a Saturday afternoon, so I decided to solder them back on and hope I didn't wreck it. I also ended up filing the spade connector, it was a little too wide. I'm not sure if the problem was caused by the harness or the CVR, both are reproduction parts. Thankfully, it worked after all that or I would have been out $20.
