Here's a different way than the page says but it will still work.
Parts:
(1) Fuse extender... . you can get these at any parts store for about $10. 00.
(2) 4" 16 gauge wires
(1) male wire spade
(2) female wire spades
(1) 20 amp fuse
1. Attach one end of the 16 ga. wire to the end of the wire from the "Extend-a-fuse" and put a female spade connector on the other end.
2. Put a male spade connector on one end of the remaining wire and a female spade on the other.
3. Pull the silver circuit breaker for power windows from the fuse box and attach the wire from the "extend-a-fuse" to the top spade of the circuit breaker, and the female spade from the other wire to the bottom spade. ("top" and "bottom" are determined by the way the circuit breaker came out of the fuse box)
4. With the wire that is on the bottom spade of the circuit breaker, put the male end into the bottom hole from where the power windows circuit breaker came from.
5. Put the 20 amp fuse into the extend-a-fuse and plug the extend-a-fuse into the #16 "spare" fuse receptacle.
6. Tuck the circuit breaker under the fuse box and put the cover back on.
That should be it. The # 16 "Spare" is powered on with the key on the "ON" and "ACC" position. So your windows will work with the key in the "ON" or "ACC" position.
