I bought the alpine 9873. I also have the mitah adapter as well as the factory harness adapter which came together. I'm ONLY changing the head unit and will be using the factory amp, speakers, sub. Ive been following the links, but i'm still unclear. My questions are:

1. The Mitah adapter has 4 pre outs, one set of the preouts has a red label, the other set has a black label. The head unit has the top set of white and red labled 'F', the bottom is labled SW/R, what is the correct way to hook this up?

2. The blue wire off the mitah, I'll connect to the blue/white on the alpine harness, correct? That blue/white is the only wire i'll be using off the alpine harness which would leave the other 5-8 alpine wires hanging there unused?

3. (The dumbest question) Do I use the factory harness connector/piece that came with the mitah? This is a platstic box with connections for dimming, illumination, dimmer and so on. If so, I assume then I need to crimp the wires on that harness piece with the wires on the alpine harness?

Thanks

 

Complete. Sounds and looks great...

 

Ha! Now my pass tailight is out and my fan/temp guage lights don't work. Two other guys have the same problem.
I used the 10mm bolt at the back of the stereo slot to ground. I twisted the orange wire with the orange/white wire on the factory harness (dimmer and illumination) adapter together and connected it to the one orange wire on the alpine harness.
I twisted the blue wire from the mita connector with the blue wire on the on the factory harness adapter and connected it to the blue/white wire on the alpine harness. Everything else was red->red, yellow->yellow and so on.
Thoughts?

 

You twisted orange wires? You twisted negative dimmer and positive illumination? WOW You only using illumination wire on units like alpine. And dude let somebody else install it, I am installer and from what you are writing... please don't do that.

 

Indeed I did, I'll go back and correct that. Thanks for the tip. I had posted a question earlier on the subject, I didn't receive any feedback.

 

Fuse IS blown, corrected the orange wire setup.

 

Cool. PM me if you have any questions.

 

Fuse fixed it. The cig ring light doesn't work however. It's providing power and heats up, but no light. Not as worried about that as I was about the other pieces.
So I'll wait 2 days, amount of time it took to blow last time, and see. If you don't hear from me, the fuse fixed it...
