One thing that has driven me nuts since i started tearing apart my radio is that i lost control of my steering wheel buttons. I bought PAC SWI-JACK to integrate my Alpine CDA-9886, but after seeing how you need a friggen' engineering degree to read the instructions and set it up, i quietly put the SWI back in its package and gave up.
Metra has a sub-company called AXXESS which also makes Steering wheel interfaces. After reading on here about everyone else having success with this plug and play miracle, i picked on up online for 45 bucks. Well, today ( 3 months later), i decided to put it in.
The ONLY problem that i ran into was that the wires the instructions told me to use on the interface unit were completely wrong. Maybe i read the instructions wrong, maybe i'm color blind, who know...but i figured it out.
It was a four wire connect, and because we have Tacomas, 3 of those wires were just sitting there, taped together on the back of a white pin connector. i cut the connector off, twisted and taped up my connections, and connected the fourth wire. it powered up, taught itself, and i was immediately able to use all functions of the steering wheel. the wires i used are below:
Tacoma Color or Radio Harness Color - (connects to SWI wire color)
White/ red stripe
from Tacoma- (BLACK ground wire from the SWI AND your radio's black ground wire) - yes, you will have your white and red Tacoma wire, connected to the SWI BLACK ground wire that is also connected to your RADIO's black ground wire - a three way connection.
From Tacoma- (aqua light blue wire with pink stripe)
yellow/ black stripe
From Tacoma- (dark green wire with orange stripe)
Red / solid red wire
From Radio Harness- Red / solid red on your radio harness (power wire)
in the back of your radio (depending on radio type) - 3.5mm male end from your SWI. (ah-duh)
After that, it was simply turning on the ignition, letting the SWI do its checks and lights, and then a radio test. I was able to determine that the instructions were telling me something differently than the SWI because of the blinking LED.
It will flash very fast in the beginning just after you turn on power in the car. then, it will pause, then it goes into two series of 7 blinks. PAY ATTENTION HERE, because this little beauty tells you what you F'd up! the first 7 blinks (short or long) are telling you what wires are hooked up that should be. For instance, mine had 4 short blinks, a long blink, and then two short blinks. It told me that somehow i had hooked up the fifth pin wire instead of the necessary 4th. the SECOND (quicker) set of blinks is to tell you what kind of radio your SWI thinks it is connected to. In my case, it was connected to an Alpine and that is exactly what the seven blinks told me. Then, the SWI will stay on solidly and you can test your buttons. If you get a slow blinking light, you F'd up and need to start trouble shooting.
All in all, with my screw ups, and my trouble shooting, it took about an hour. VERY LITTLE button lag, I'd say it's as fast as it was stock Pictures below
