Prostate removal, make sure to use the Di-electric grease on everything, I did all the blacks first, then one colored wire at a time, after all was done I went back and did one connector at a time and removed all the wires with electrical wire numbering system attached to each wire and put shrink tube on the wires, reinstalled and then heatd shrink tube to clean up installation. This last part was done after verifying the wiring job was good when I heard the Dog roaring again. I also went for about three days starting at different intervals to make sure it was a go. So far Egon alls well. Just take your time and double and triple check connections and the wires, I even went the extra mile and crossed off each step in the instructions after I put each wire in the correct plug. If you have any issues there are lots of capable people on here my self included to help you through this. Good luck and let me know how it goes for you. One last thing I did go the extra mile and soldered everything instead of getting one of the crimpers and apparently it worked so if you solder pretty well you might take this route. If you do be aware that you don't want any solder build up on the back side of the ring on the pins for this is the surface that locks the pin into the plug. Hope all goes well.
