I am glad to see Crutchfield steered you in the right direction... Definitely plugs into the plugs on passenger side of transmission tunnel.. As for the antenna, the brand of radio is often the cause of the antenna staying up issue.. Pioneer is notorious for this but brands such as Alpine have the ability to lower antenna when CD or any source is being used but the AM/FM.. It mainly depends on brandname and what decks have this ability..

Also, you an easily get an amplified bass tube or aftermarket 2/1 channel amp with bass crossover that will connect from the RCA's on the radio and supply power to the stock subwoofer.. You will probably blow it eventually but this is a temporary fix to get your 'bass fix'..

Feel free to post any other questions if needed...

The harness that Metra has always marketed is a generic type one that is used on all Toyotas and is meant to bypass the factory amp and use deck power.. The additional amp is about the only way to go without a 'custom' harness.. You can get an amplified bass tube for under $100 on Ebay and hook it to the RCA's for some bass and can be removed for extra room if needed.. The Pioneer is good radio just doesn't allow for antenna going up and down...
