I just did the locker bypass and it will still only lock in low 4. Does anyone know if you can just cut the wires to pins 4 and 5 and leave them hanging, or does the computer need a logical "0" for it to work right?
Sounds like you maybe did the wrong wires. The wire color changed either from the 04 to 05 year or sometime around then. What you are basically looking to do is trick the computer into thinking that it is in 4Lo. By grounding the 4Lo indicator wire from the switch it allows you to lock in 2Hi and 4Hi. Check the web for wiring diagrams but I remember reading that the wire color for the 4Lo indicator changed over the years.
There is a great thread on here for this I did it and it worked fine i think it is called Locker Bypass great pics and wiring diagrams I used the little clamps that go around the wire and then you insert a spade connector took like 30 minutes find that thread it will help you out
