It seems I may be able to help.
Sorry for taking so long to share what Ive learnt so far with you.
Below is my result so far.

Ive recently had to upgrade my Mcintosh HU so I got onto a reasonably priced 06-07 Mcintosh HU with the optional AUX input and Mp3 capabilities.
Almost a straight install.
There in starts my challenge.

The i85 plug is slightly different. (That means it wont fit) This plug only had 1x green wire from it. Even with the old unit I could not work out what this wire was for. Everything worked fine, with or without it.
The i86 plug fit perfectly. I worked out these wires controlled the Steering wheel controls with the old HU (everything else still worked fine) BUT with the new HU the Wheel controls no longer work.
All other plugs and features work fine including my Clarion ipod control with Clarion aux input.
Does anyone have a cut off i85 & i86 plug they dont want for a 06-07 Mcintosh HU?
I presume this will fix my i85 prob & correct the pin order of i86 OR have I got it all wrong.
Sorry for the long winded version, I havent learnt the shorthand yet.
Cheers

PS I have yet to resolve my issue BUT I hope I can get together in the next month or so, with a Techo aquaintance to work it out.
Now that life is back to normal after purchase (i.e no money), it takes me forever to take care of technical things.
i.e Still no Steering wheel music control and no Bright (dimmer) of HU fix.
