So I as at my parent’s house recently and found myself in a hard spot when I wanted to listen to my iPod on my Pioneer DEH-P4500MP. I was leaving that Sunday to go back to New Orleans and buying a cable on Ebay wasn’t an option. I called to every one of their local car audio shops in Alexandria and nobody had an IP-BUS adapter. The only shop in town that could order me one wanted $70.00 for it!
I thought that $70.00 was WAY to much for a simple cable. I figured that I reprogram routers, build computers, and hack IPods then I could make a simple cable. I started searching around on Google and found this website: http://stereophonik.com/gutterslide/IP-BUS_Hack/
The author outlines and makes clear the instructions on how to make your own IP-BUS cable.
Well I didn’t have any motherboard plugs as the author describes because I was on vacation and I don’t carry this stuff around me (my fiance’ would tell you otherwise). I decided to go to Radio Shack and use molex pin
connectors (what you would find on a computer power supply). The hack worked with the molex pins but I had to squish them down with some needle nose pliers otherwise they would make contact with more than just the intended pin.
I’m not going to re-hash stereophonik.com’s instructions but here are the pictures and subsequent steps I took to achieve my $5.00 IP-BUS hack
I had to, like I mentioned, squish the plugs in to make a smaller plug then what came out of the box. You can see the four plugs that the author mentions in his (her) website clearly in my pictures. The plugs around them I’ll never use and you’ll see later why that is so I bend them down but taking care to NOT let them touch each other.


Then I put shrink tubing over the molex plugs I put on the IP-BUS pins. This was partly to prevent movement of the molex plugs but mainly to prevent the plugs themselves from touching each other. I used a blow dryer to shrink the tubing on the plugs.

I borrowed a hot glue gun and just filled the IP-BUS bay with loads of hot glue. Be warned that if you do the same that you MUST have a great contact between the molex plugs and IP-BUS pins otherwise after this step good luck changing anything.

Because I was leaving in a few hours to go out of town I needed to get this project done FAST. Normally I don’t do this with ANY of my hardware but I stuck my Pioneer in the freezer to rapidly cool the hot glue and boy did it cool fast!

The finished product was a hot glue’d IP-BUS bay.

Finally I connected my RCA plug wires (as described in the instructions on the author’s website), soldered those to the ends of the molex plugs, and shrink tubed those wires. To top it off I used the remaining amount of hot glue I had. These wires are going NOWHERE! 

Here is a short video clip of the iPod in use on my stereo once I got it back in my SUV. Sorry for the bells or whatever it is in the song, if I had known it I would have used a much “softer” song (something you’d find on the Chillout channel from DI.fm). I demonstrated volume up, volume down, song seek, play and pause. You can view the video here: http://www.youtube.com/watch?v=pXOowT4r4S4
