Beware. I am not sure all the android head unit pinouts are the same in their ISO connectors. No personal evidence of that but going off of listings for the extension cables they are careful to say they will only work with a certain android radio or group of radios.

That's what I was getting at in the above post. You can skip the 40 pin at the front for the head unit and wire the ISO directly to the extension harness. If you buy a head unit supplied with the extension cable... that's how it should come. My Avin 2 and the current Android unit came that way. Came with extra harnesses too, like the older style round pin harnesses in the rear as well as an extra pair of harnesses of each style which I can only guess is to retain the original radio unit in the back to keep OBC functionality? I cut all of that out of my harness though and only kept the 40 pin and canbus connectors at the back and left the front ISO termination alone.

Yes, again, definitely skip the 40pin adapter up front if you want. The harness I posted was designed to be used with a head unit that only supplied with a short quadlock to ISO connector. They figure the short harness supplied with your radio will have the CANbus on it. As to NEEDING CANbus because of having iBus... I don't know. I am going to have both connected in mine and just use the CAN signals for the radio and iBus for OBC and other functionality. If you are following Resler's iBus recommendations... run the iBus interface wires from the back up to the front along with your extension harness. I am going to use the nav unit's connections because at the time I read his instructions it did not recommend the rear connection method as being superior to other places to tap into the iBus signals.
Okay, I just looked at what you ordered... is that ISO on both ends? Male and female? Did your radio come with a short (~12") quadlock adapter with canbus harness on it? If it did then all you have to do is combine the two harnesses. Cut the end off the one you want to go the rear and solder on the quadlock to connect to the OEM harness. Be sure to check pinouts stay the same though.
