Query: Did not fit 2005 Silverado

Soldered all the connections from the head unit to this harness. Pulled out the factory unit, the connectors are different. i had to get the Metra 70-2003 Radio Wiring Harness For GM 98-Up Harness. The Metra 70-2003 Radio Wiring Harness For GM 98-Up comes with a red wire that needs to be connected the to fuse box and the red wire of the head unit. I guess the red wire on the Metra 70-2003 goes to nothing on the factor 2005 harness, no 12v, like the others have said. Connecting the red 12v wire to the fuse box is advanced. I'm not doing it. Taking it to Best Buy for $160.
