Tony thats because the 2002 and older trucks have all of the electrical architecture sophistication of a 1985 K30. Jumper this, short that, resistor this, swap that wire. Great.

doesnt work on the 2003+ trucks. They use computers/databus for EVERYTHING.

01-02 are the best, just admit it.

BTW, if a light bulb inside the push buton TC control gets 12v power by pushing the 4x4 button then all you really have to do is borrow that power for the dash light just like I did on my 2002, you make it overcomplicated Ben.

It's a light bulb, it doesn't give two shits how it gets power to light it up, in the end its juts a light bulb, solder a dam jumper and be done with it.

By the time you find a calibration you could have soldered a jumper in, and I think it will light it up, it's still just a bulb in a cluster.

:confused:

Tony the problem I have with the jumper wire mod on the 2003+ trucks is because when you dim the dash lights, you get a feedback loop through the LED-dimming circuit (2003+ trucks have two separate dimming circuits, 0-3v LED dimming circuit and a 0-13v incandescent bulb dimming circuit) that causes the 4x4 indicator to illuminate dimly when you have the instrument panel lights dimmer set at anything less than full instrument panel light brightness.

Its annoying as crap to me, having to look at a half-lit 4x4 indicator on the instrument cluster (even when Im in 2wd) because I always drive at night with my instrument panel lights at ~50% brightness. Maybe im sensitive to light at night, I dont know.

I took apart my cluster and soldered in the "easy jumper mod", but I ended up just ripping it out after a year or so because it was so obnoxious, and I was tired of people asking me at night time with the IP lights dimmed "WHY ARE YOU IN 4 WHEEL DRIVE?? ITS SUMMER.".

So yes, THIS is the right way to do it because you dont have the annoying downside of the "jumper wire mod" on the 2003+ trucks. And it takes 2 minutes (a literal 2 minutes, not a "pretty much 2 minutes" like the jumper mod takes) to reflash it. Ill race you for 50 bucks to see who can make the light work faster. Me reflashing and you taking the thing apart and soldering it.....
