The info I got on wiring the blue antenna wire to the blue/white wire is found here:
My Pioneer AVH-X3500BHS Head Unit Installation - Toyota 4Runner Forum - Largest 4Runner Forum
That post also mentioned the remedy for using a microbypass is wiring the antenna wire to the yellow acc wire. This is what confused me and made me wonder how to wire it up to the yellow acc wire.
I am not ordering from Crutchfield to try to save some money so I don't have the instructions laid out as well as they do.
Do it correctly unless you are going to use a amp leave that control wire alone. you could have just purchased a 4 prong relay connected the parking brake pink to it and then ground it out.
I have a pioneer and I simply followed the paper work and then added the the relay for watching movies that was until of course I met someone that worked for pioneer who gave me the factory code for programming it. at that point I went in and removed the relay capped off what isn't used and while in there connected the backup camera.
Just saying i rather do it the way Professionals in the field would do it rather then following a thread on a car forum. Granted there are ALOT of knowledgable folks here, granted it may work BUT the key word for line for me was I FOUND THE WORK AROUND. Not sure way they were having a antenna issue but I can say I didn't and I have the same truck and brand of stereo
I have been unfortunate enough to have a car catch on fire due to a faulty HID harness and also was in a holiday inn that had water dripping on the hot wire inside the wall which caught fire inside of my room had it not been for the dog waking me up it may have been to late in either case its not a very pleasant feeling.
So I learned I don't **** with electric and do it according to the every day professionals in that particular field. It eliminates me from the problem and makes them responsible in the end granted the car stereo is low voltage.
As far as the steering wheel adaptor sorry cant help they are a PIA, add way more wires inside the dash then needed and they are a SOB to program. I don't see a point to needing the stereo wheel controls when I have the remote for the stereo right next to me and the actual stereo half a arm reach away.
BTW is you decide to add a back up cam you need a REVERSED IMAGE camera otherwise the image with be backwards aka right will be left and vice versa its pioneers way of screwing people
