im doing a full system not using the stock bose, what harness/adapter to buy

 

Metra 70-7550 wiring harness

 

You might want to use teh 70-7551 instead if you want to reuse the stock bose amp. I'm pretty sure it's better then the one in the receiver. You'll also need one for the antenna, i think 40-NI10 (correction?).

 

I'm using the 70-7551 but the dush helping me decided we didn't need it and cut every single wire in my dash😭🤬🤬. Now im wondering if he did the bose amp bypass correctly? I really could use color coding diagram cause all thus is really beyond my knowledge. I read that bose amp bypass thread but it doesn't make sense to me im a total noob when it comes to radios 🤦‍♂️
