2011 D Max radio changeover.

This is going to be a bit involved but here goes. All done in vertical rows
looking into the rear of the OE unit the connections are from the various "bays: or segmented sections. 16 pins in all. with the unit correct way up, ie top at top.
Bay 1 (LHS of port )two pins one above the other.
Top is FR spk+ve
Bottom is FR spkr -ve
next vertical row in next bay before gap with double rail.
Top FL spkr +ve
Bottom FL spkr -ve

Third vertical row from LEFT of connector.
Top pin NOT CONNECTED.
Bottom pin BUp +ve supply ie, always powered.
NEXT two bottom row pins are under the double rail gap.
Both NOT connected.
4th vertical row, ie after centre gap
Top pin ACC and ign on from Battery +ve determined by the key of course.
Bottom pin ANT +ve for aerial
5th vertical double pin row
Top pin Not connected
Bottom pin Illumination ie dash light circuit.
6th double row,ie, lhs of last bay on right.
Top pin RR spk +ve
Bottom Pin RR spkr -ve
7th row of double pins, ie last one on the right of connector
Top pin RL spkr +ve
Bottom pin RL spkr -ve
The OE unit is connected to negative through it's case so a definite neg connection is normally made through that.
The new one may be the same but there is no direct connection to neg in the OE loom as far as I know.
Hope this helps.
I opened my OE unit to read the pin designations direct off the board.

I did not use a loom adapter, I simply soldered/crimped pins to the new wire plug loom and inserted them into the OE vehicle plug in the corret places as per the above info. All wire held in with a run of hot melt glue and suitably taped to ensure no drop outs of pins in action.

OE Original Equipment as supplied by the manufacturer ?

I found the wiring colours I determined from the OE unit.
In the OE loom plug.

These 4 pins front spkrs but the two vertical rows are slightly separated by a small gap.
FR spkr Green +ve Grey-ve
FL spkr. Blue +ve Yellow -ve

Red /blk. not connected
RED/White. Battery backup , ie direct full time supply.

Green/Yellow not connected
Red/Blue antenna

Red/Yellow. ACC. Key on .

Green/Red Illumination

Blue/red not connected.
Blk ground ( different to what I mentioned earlier)

These 4 pins in separate section by themselves. Rear spkrs. Separate from centre by a larger gap.
Orange. R R spkr +ve
Blk under that orange one RR spkr neg
Red RL spkr +ve
White RL spkr -ve.



Red RL spkr +ve
