Apparently you solder them as it's more permanent and you don't have the correct (expensive) crimper.

Since you don't have an actual sled in front of you to copy, just use the wiring diagram to hook up what you need. If you can't ever see yourself using cell phone mute, no need to put a wire there.

Finally do not forget to put an inline power fuse as was in the original sled. I think the necessary info (3 amps?) is in the FAQ.

Although it's not too important to get exactly correct, you'll also nee the correct guage wire. I imagine the original wiring was around 20 AWG?
