2006 Toyota Tundra TPMS Bypass. Easy fix. 

Did it yesterday on my 06 SR5. Grounded the splice to the lower right nut that holds the radio in place. Worked like a charm. 20 minute job. Thanks.

Thanks for the info! I also have an 06 DC with the same issue. Blk electrical tape helps to cover the blinking light, but is still an annoyance at night! I have installed an aftermarket radio head unit, so I am familiar with taking the bezel and radio out to get to the module. I am glad to know which wire I can ID to stop this annoyance!

Thank you. It worked perfectly

Can you just cut the pink wire?

So you just grounded the pink wire? Is that right??

That's all. Completely dismantle your dash. That's all.
