I just finished putting together the prototype board with the relays all working as they should be. Its a nasty looking beast of a prototype board but its working. I will be testing out the features of switching the video and disabling the IEBus signal from reaching the navigation computer while in “PC” mode tomorrow afternoon. For now I have posted some pictures of the board below. Enjoy!

Here is a diagram that I put together to show how I used both the 20 pin and the 8 pin (C) connector together to form a completely plug and playable solution for Dom’s video converter box.
(Both plug N play harnesses featured in this diagram are available for sale through this website. Email robbienewton (at) gmail (dot) com if you are interested)

Just thought it worth mentioning that if anyone needs any of the 16 pin connectors, I have a few available. It came to mind because a guy by the name of Garrick Lau sent me an email asking if I had any I could sell to him. He is working on completely replacing the navigation system in his 04 NSX! He needed the 16 pin for the XM connection that includes XM traffic.

I have began working with the PD72042B again thanks to some chats with Slden over in Russia. He is not using it himself, but in talking to him he gave me some ideas. Now that I am working on a new schematic in the Eagle Cad software I need a library of the chip but one is not provided by EagleSoft (obviously).
I have created a library for the PD72042B in the past but it was not good enough to use on a real board. So this time around I decided I would take my time and really put it together as it should be. Its created from all of the package information provided in the NEC data sheet which can be found here:
http://www.necel.com/function/en/iebus/d72042b.html.
The package is a 16-PIN PLASTIC SOP. I have attached the Eagle library file below, named IEBus.lbr. Leave a comment if you get some use out of it or if you find any problems with it. I have not produced a board from this at the time of posting, so please pay close attention to the pads before sending off anywhere to be made just to be sure. I would hate for someone to waste some money on one of my silly mistakes.
Get the lib file here:

I decided to go ahead and place the order for the C connectors. Due to a request I received in email, I will be selling both a harness that will terminate to a DB9 connector (just like the AH-20 harness) as well as a DIY kit that will come with a plug, cap, DB9 connector and 10 of the special metal connectors needed for assembly of the 8 pin plug (two extras).
I have also decided to offer a DIY kit for the AH20 harness. It will include both the plug and the cap connectors, the DB9 connector and 25 of the special metal connectors needed for assembly of the 20 pin plug (5 extras).
Contact me via, robbienewton [aT] gmail [d0t] com to place an order!

I may be able to get some of the C connectors (8 pin) for the back of the navigation unit. Would anyone be interested in a harness to gain access to the wires on that plug without damaging anything?
So far I have had one person request it and have been thinking about doing it for myself to get to ACC, Power, and Diagnostics in the trunk. With a simple little harness for this you could make any solution involving those wires, plug n’ playable.
Let me know if it would be worth it for me to order some. It has to be a bulk order, therefore it would be quite an investment on my part, so if you care, please leave some feedback.
The reference to the “C” connector is from my 2006 ETM. Click on the thumbnail below to see a PDF with an image of the connector.
