I have a 2001 Yukon and have pulled the radio to replace it with a 2 din screen aftermarket product. Checking the power plug I find there is no 12v. Fuse is good and I suspect the anti-theft thing with these models. No problem, I can run power from somewhere else. Does anyone know an easy place to get power from. I need switched power and and always hot. The always hot will draw about 5A and the switched just a little current to turn the radio on. Hopefully someone else has done this before. Thanks in advance. Cheers, Wavelength.
