I bit the bullet and bought the Pioneer AVH-W4400NEX with ready harness from Crutchfield. It's been a while since I did a radio install so I was a bit rusty. This was also my first double din. I went and got a MicroBypass for the brake bypass.

SO...

I managed to solder the Microbypass to the brake wire (green), ground wire (black), and amp wire (blue/white unit side). All went well until I realized that the ready harness that I bought had the blue/white spliced onto a blue and connected to nothing on the car side. Forgetting what each wire was I panicked, assumed Crutch screwed up, and removed the pin and placed it into the only one that didn't have a wire......The red aka Dimmer. Emailed both MicroBypass and Crutch and was called an idiot (at least I know they did when reading my email). Microbypass corrected my reverse thinking in that the blue/white sends the 12V out not receives it and Crutch sent me the harness diagram. This is where I got a bit lost.

I emailed them back with a "my bad I'm a dumbass" reply (never letting Crutch know I did the bypass). The blue pin is back where it belongs and the bypass works.

However, when I look at the diagram, I see that the car side harness pin#10 POWER ANTENNA has a missing wire (yellow/green).
Does this mean my 4dr LX doesn't need the ant. booster? And where, exactly, is the booster located if I wanted to see if I had one?

Also, the diagram that Crutchfield gave me matched 99% of how my car harness looks with the exception of two wires. Can someone explain this to me?

PIN #1 CONSTANT 12 V WHITE/RED
PIN #14 RIGHT FRONT SPKR- GREY/RED
but the harness has it reversed. Or am I misinterpreting what that grey dash is on pin #1 ?

According to my diagrams, sedan did not have an antenna amp. Coupe did.


Sedan/Coupe have a few wiring differences. Plus your numbering doesn't match the factory diagram, maybe you counted from the wrong end of the plug?

factory plugs:
Pin A 1 (yel/grn) in a coupe would be the switched power out to the antenna booster, which is not needed on a sedan (empty hole).
Pin A 10 (wht/red) is constant power on both coupe and sedan.
Pin A 11-14 are all empty
Pin A 17 (gry/red) is RF spkr neg on both coupe and sedan

Yeah this should be a remote wire to turn on an amp if you had a sub amp or 4 channel amp in the car. It just turns the amp on with the radio so the amp isn't on all the time draining the battery.


If I remember right from my car audio days this refers to if the car has a motorized antenna. When you turn the car on the antenna extends out of the fender and then retracts when you turn the car off. I don't think it applies for these cars.


I think so, the speaker wire looks red/gray in one picture and then red/white in the 2nd picture. In the pic on the left it looks red/gray but on the right it looks red/white but it's the same wire. The red/white with the little gray bands should be the 12V constant.

Well ****. I didn't notice it was grey on the top. I swear it looked white and the other with the grey dashes threw me off.
