Ok, so I bought the relocation harness to move the stock radio to the trunk and make room for the new aftermarket deck. I bought the Metra 70-2003T, but theres no switched 12 volts in the harness. It came with a separate red wire, which I'm guessing is to use to tap into a power source. I cant find anything besides a constant 12V, which of course i dont want to use, I want the radio to turn on and off with the key. Anybody know where I'm supposed to tap?

Hi guys I have been working on my 2000 impala getting a 7in dvd cd radio nav system installed , i tryed the relocation harness but found that was a waste of time. I bought a intergration harness from hifisoundconnection called the gmco for the impala, I also had the idea that the factory radio had to be there to reset low tire and oillife , but there is other ways to reset them. these are the most common things that will come up . you can find the things you need to know about your impala on a web site called( impala how to's.) there is a help on there for a power connection up behind the glovebox and how to reset the oillife and the low tire lights. there is a power wire on the relocation harness if you still go that way. for your memory to keep your stations settings, use the yellow wire to yellow on the deck there should be power from your factoy harness to the relocation harness when it is pluged into it, best to use a light tester and see whitch one comes on with the ignition.Are you going with RCAs off the deck to a amp or just factory wires to the speakers useing the factoy amp,IF NOT RCAs. the SPEAKER wires are the same, its just gray to gray white to white and green to green purple to purple. The only thing with the intergration harness i had to connect the blue power from the deck to the blue wire that said power antanna to power up the factory amp. It also has all the chimes and warning sounds on it, works well. Sometimes i ramble on, does this sound like it will help.
