Jump to post 45 and you'll see the resistor voltage divider. You need to make one of those up. Clipping the wires turned out to not work.

Just to clarify; adding the switch doesn't really make it any easier. If you want to do it without the switch, you build the voltage divider shown below (from page 3 of this thread). You unplug the TPWS connector (and leave it disconnected) and connect the red wire to the red wire show below, the black wire to the white wire shown below, and you connect the green wire to the brown wire below.

The switch method is just for people who run two sets of rims with one of the two sets still having the sensors installed.

Ok so a few days ago I did this. I added a switch. And it worked perfect for a few days. But now the light flashes and when I turn the switch off is stays on (doesn't flash).

Measure the voltage on the brown wire.

It's the ECU-IG 10A fuse.

In the fuse panel that faces the driver's side floor mat at the bottom left of the dash.

You're looking in the wrong place. Lay on the floor and look up at the bottom of the dash (directly under where you are looking). You'll see a plastic panel with the fuse locations. Pull that plastic cover off and the fuses will be visible.

but now when I turn my headlights on the instrument panel goes dim, under daytime running lights the dash is illuminated, very odd and can't find anything in the owners manual.

That's the normal behavior for the instrument panel lighting - Full bright with headlights off and dimmed, per the knob, with headlights on.
