Since there is no clear tutorial on the web I will submit it! 

I have made a few plugs from wii2hdmi converters.

These converters are plenty and cheap, they do not upscale,  unless you buy more expensive wii2hdmi plugs with a hole on the top. 

To follow this tutorial you need a few items:

(aftermarket preferred)  av cable

Wii2hdmi converter

Thin wire

 

A few tools:

Soldering iron, preferred regulated station. 

Sharp knife

Cutting tools for metal (angle grinder is fast) 

Electrical wire stripper/cutter

A pocket knife or small screwdriver. 

I used a chinese av cable, the long and short soldering connections are opposite to original! 

Just follow the pictures and you will be on hdmi in no-time. 

Reminder,  the wii2hdmi boards are very sensitive to static electricity,  i have busted a few.

Cut of the connector.

Cut in the sides to release easily.

cut the metal on the black line. IMG-20180324-WA0007.thumb.jpg.ad07965794daabd6120b9dab00a18500.jpg

bend the pins open as far as possible,  this will sturdy up the connector. IMG-20180324-WA0009.thumb.jpg.a02ce5323a7f8d772e4541187f1b4d68.jpg

remove the hot glue,  on original cables it is a piece of tape. IMG-20180324-WA0010.thumb.jpg.ffd9ce430f7709f3891fdfff503afff3.jpg

desolder the wires.

place the mode selector connections,  use the shortes wire you can,  unshielded is o.k.IMG-20180324-WA0013.thumb.jpg.724be1fa10f941bb90f58b47a88123fc.jpgIMG-20180324-WA0014.thumb.jpg.014bf6de37d0524bdbf58df1f113cd34.jpgIMG-20180324-WA0016.thumb.jpg.fbd2563b5dd505e49163fea3cb2c0300.jpgIMG-20180324-WA0015.thumb.jpg.2beb8948962ba4936f13e98bcd748082.jpgIMG-20180324-WA0017.thumb.jpg.cdcd1b115b5f50ec26196e4403171d2a.jpgopen up the wii2hdmi and snap off the connector. IMG-20180324-WA0018.thumb.jpg.e732d1c541b6f17d382d6fe03946f567.jpgclean all the contactsIMG-20180324-WA0021.thumb.jpg.46ca14eb8afd68b8276dab41e57dafe6.jpgIMG-20180324-WA0022.thumb.jpg.88b69acf6fbb0593582efd3650158b64.jpgIMG-20180324-WA0024.thumb.jpg.903b92b9acda87181682c104943928f4.jpg

make the first connection,  it will sturdy fings up,  the lid has the exact size you need. IMG-20180324-WA0023.thumb.jpg.d647458ea11c252f7d90d31b2cd9a03a.jpgwith 2 cables installed, you do not need the spacer anymore. 

make sure all the cables are as short as possible and don't short out each other! IMG-20180324-WA0025.thumb.jpg.8d1dcb7a1aa334f7e41607af73ab732a.jpg

add a piece of insulation tape at both sides. It is wise to test it at this stage,  later on it will be a pain in the a**.IMG-20180324-WA0019.thumb.jpg.212671246630ce664080b37dffc36919.jpgIMG-20180324-WA0020.thumb.jpg.a116a4ace01372ff50ccd8e698214467.jpg

measure and cut the hole for the metal,  it should slide in without to much hussle. IMG-20180324-WA0026.thumb.jpg.4de5923fba49d7be29dac7c9057d3e96.jpg

cut the top metal piece at the black line. IMG-20180324-WA0027.thumb.jpg.cc61e18002d49bcc3e2a8975c68e7a25.jpg

slide the metal piece in as far as possible.  This will hold the internals in place! IMG-20180324-WA0028.thumb.jpg.a2675cc2bb54d77b3829fd046cacbb9a.jpg

solder it at the top and the sides. Your plug will not fall apart if you remove it from the xbox this way. IMG-20180324-WA0029.thumb.jpg.282588aee154cc7efa8c73b63d36a15c.jpg

insert the completed converter,  IMG-20180324-WA0030.thumb.jpg.40a163f4a767519136afd4f21535f12a.jpg

push it through as far as possible and solder a wire to the top and bottom,  against the plastic,  this will keep the internals in place and removes stress on the converter. IMG-20180324-WA0031.thumb.jpg.f7ca357008ac6d10443ee378067e979c.jpg

time to test! IMG-20180324-WA0032.thumb.jpg.c9775bcdca9fcdb45df6e41b3a8efeb5.jpg

720x480@60i, the boot screen,  some tv units have problems displaying this throigh hdmi! IMG-20180324-WA0033.thumb.jpg.73369f9d29fec6a2a01305564ec7dac9.jpg

we have reached 1920x1080@60i, maximum resolution of xbmc,  although I advice to use 720.

If you miss the options for higher resolution,  make sure the system is set to NTSC,  in pal it is unavailable.  Use enigma video switcher. 

I will start to sell these adapters in a short while for €45,- due to the work it takes. 

 

I have given all the connection types another color and the pin numbers are not the official ones! 

Any questions?  Be free to ask.

If you are very lucky you can get one with a ms9282 converter chip,  instead of this one.... 

The ms9282 can handle digital audio in! 

Maybe this one also,  but there is no datasheet for these.

Very nice writeup and pictures. I did the same some weeks ago with mixed results. There seem to be several revisions and versions of the wii2hdmi board. Some will do 1080i, some 720p and some only 480p like mine (came in a black housing).

Did you set your xbox to ntsc and enable the higher resolutions in the system settings?  

 

I used the cheapest converters i could find on aliexpress.  They did the job fine.

I have noticed a little problem with using the converter... 

 

When using on a smaller tv al is fine. 

When i use the larger tv in the living room lots of black screens. 

The xbox resolution with a lot of games is 480i, this gives problems with lots of tv sets. 

Have found alternate bios files to force 480p on all games,  this takes complete care of the problem. 

Downside is that you can not use the original cables anymore, they do not support 480i.

Will supply the force 480P bioses soon.

Force 480p bios does not solve the black screen on large tv's. 

The real problem is that larger tv sets do not understand 480p in a 4:3 screen size. 

I am trying to get a login for assemblergames,  mr nova over there created the 480p bios. 

I would like to know how,  so i can create a force 480P widescreen bios. 

Dies anyone here have a account on assemblergames?

are you 100% sure about that, and do other HDMI solutions like N64's and Pound's suffer of the same thing?

I am not 100% sure but when i plug it in to a smaller set it works fine, with the large i have black screens. 

This only occurs with games that are in 480 and are 4:3.

Have no other solutions to test yet. 

Will receive a converter from n64 to conduct tests.

      Hey guys,  So @N64 freak posted his awesome PCB HDMI converter in another thread.  With luck he will be able to make these available for everyone.  Until such a time I am annoyed with having my DIY Component cable going into a cheap amazon converter.  I figure it would be easy enough to do the "dirty version" where you gut a converter down to the PCB and solder wires to the mobo.  In researching the pinout of the AV connector on the mobo i found a great post from a gent named William Quade.  He did a nice write up on his blog about doing it and I thought i'd share it here in case someone else is interested. 
      Please login or register to see this link.
       
      Note:  He admits his hole for the HDMI port is terrible and I recommend anyone who's doing this mod do it properly with a panel mount HDMI or at the very least, cut the hole with a dremel.  His looks like a tiny bear was trying to get into his xbox but the point of the blog post was to show where you need to solder which is the important part.

      So finally they are completely ready and for sale now
      I can offer 2 Versions off the cable:
      -The first offers stereo audio on the HDMI signal and 5.1/digital audio through the optical port.
      -And one second does offer 5.1/digital audio on the HDMI sigbnal and through the optical port.
      The price for the cable that only has stereo on the HDMI signal is 65€ (~87US$) +shipping cost 3,70€ (~4,30US$) and paypal fees.
      For the fully digital version that also offers 5.1 through the hdmi signal the price is 70€ +shipping cost 3,70€ (~4,30US$) and paypal fees.
      You can choose between black and white for the case color. I do also offer the Case with a cutout or as a completely closed case. You can easily illuminate the case with a couple 0603 leds and resistors. Solderpads for those are present!
      Got a couple HDMI cables ready in both the full 5.1 Version and the version that only offers stereo through the HDMI connector.
      If you have any questions just drop me a PM!
      To use the cable the Xbox needs to be set to NTSC region and then just plug it in and you connect your console to your hdmi TV!
