I just did my on today. I was pretty annoyed at the instructions though. They make it more confusing than it really is. The wire colors are inconsistent with the directions... Basically needs to say: cut the 12 gauge Blu/Rd wire from fuse #27, cap Blu/Rd wire left in place, solder/crimp new Blk wire to Blu/Rd wire, insert fuse terminal blade of new Blk wire in slot #70. Replace all the stuff removed and insert fuse. Test.
