You don't necessarily have to remove the original blade connector from the plug, you can do this without doing it. I did it mostly because I wanted to check that connection and make it a solder connection also.





Next strip back a piece on the original red wire. I used a utility razor and carefully stripped off about 1/2" or so. Then strip off about a 1/2" on the new wire and solder them together. I also soldered the crimp connection of the factory wire but that is optional.



Once the soldering is done and cooled, tape that connection up suitably with electrical tape and then tape everything together simulating the factory sleeve that was cut off earlier in the process. Connections on this end are now done.

If you have some electrical contact cleaner and dielectric grease this would be a good time to do some maintenance here while you got the connectors exposed.

If you removed the factory blade connection then put it back in the plug. Make sure it seats firmly and then grab the cover, plug the rectifier back in, make sure the blade connector didn't push out the back, and then replace the cover.
