Before I begin, here are the steps.



1. Cut the 18ga wire to your desired size using the razor blade to mark the wire at the end of the ruler and than cut with pliers)



2. Strip 3mm off each end of the 18ga wire peice using the 1/8" alum sheet and razor blade to mark it first than strip the wire at the marking)



3. Crimp atx connector pins to each end of wire



4. Measure the wire + atx pins (together) from end to end (measure in mm)



5. Take the number you get from step 4 and SUBTRACT 32mm from it



6. Take the number you get from step 5 (number from step #4 MINUS 32mm = number for step # 6) (total length - 32mm = desired length for sleeving)



7. Tape down sleeving and mark it using a razor blade



8. Cut the sleeving with scissors at the marking made at step 7



9. Fish the wire through the sleeving until each pin on each end is outside the sleeving (use the compress and pinch technique to prevent pin getting caught on sleeving)



10. Put the 15mm heatshrink peice over the heatshrink (fish it over top of sleeving)



11. Measure 18.5mm from tip of ATX pin to Starting of sleeving using a ruler



12. Position the heatshrink so that it begins at the beginning of the First crimping flaps (from the tip) ( between the 1st and 2nd crimping flaps) and than continues over top the sleeving.



13. Take the heat gun on LOW settings, and apply heat all around evenly, start where heat shrink is at its widest point. Allow the heatshrink to shrink partially, allow it to touch wire but fully shrink (looks like a balloon).



14. Position heatshrink so that it aligns perfectly at the begining of the first crimping flap (from the tip) (between 1st and 2nd flap) see pics



15. Take the heat gun and apply evenly for a quick second at top, than bottom than sides until heatshrink fully shrinks (you will see the outline of the sleeving threw the heatshrink)



16. Take your nails (index and thumb) and pinch the point where the sleeving ends (where you see it go from being thick to thin(than transition point) )



17. Adjust the amount of heatshrink that is after the sleeving, you may have to pinch at the transition point and pull the sleeving slightly to get the desire amount of heatshrink after the sleeving. (this is important because it will allow for easy seating into the connector) ( with experience you will be able to tell by the look of it)



18. Insert wire into connector (make sure the pointy part of the pin is facing the connectors flaps (where it slips into the other connector)



19. Grab the wire at the thickest point (where the wire + sleev + heatshrink are) and push into the connector until you hear two faint clicks.



20. If it does not go in and falls short, pull it out and repeat step # 16 - pinching the transition point and pulling the sleeving slightly.



21. Repeat for other side



22. Repeat for all other wires and watch all the wires line up perfectly.
