1. Take you old cable off.
2. Run cable from refill spool (don't take it all off) through downrigger pulley and through a small hole in your downrigger spool that you will run the end of the new cable through.
3. Take a connector sleeve and run the end of the cable through once and then loop through again making a small loop (about the size of a dime or less).
4. Crimp the connector sleeve 3 times ...in the middle then on each end. I use a 4D .070 size crimpable connector sleeve.
5. Have someone hold the refill spool as you crank the new cable onto your downrigger spool (keep firm as you go to avoid loose wire on your downrigger spool). Pencil placed in the refill spool will help greatly.
6. Attach the swivel to the end using a couple connector sleeves.
7. Re-calibrate your depth meter to zero estimating where your swivel will enter the water.

This should all take about 20 minutes start to finish
