I put the aux jack in my 2008 Honda fit today!!! Works Great!!! Thanks to all the contributed!!! Just some thoughts about my install: 1)The hardest part for me was Step 7 in the Honda Music Link Installation Instruction guide, where remove the two center console screws. I began by using a Phillips screw driver after fighting with that for about an hour I realized you could use a socket instead. Once I switch to the socket wrench it took about 5 minutes(I think the socket was an 8mm, don't really remember though). 2) I wasn't real sure where pin 1 started on the B connector and then I wasn't sure if 2 was to the right or below. Well going with my gut instinct I did left two right top to bottom which ended up being correct
In other words just to clarify if you look at the back of the radio as if it were still installed starting at the left side top rows goes 1-10 and bottom row goes 11-20. 3) I could also only find the two female bit connectors no luck with the single female ones, so if you turn the third set of two wires side ways for the aux jack it works fine and then on the radio I just plugged it into slot 15 and 16 and of course slot 16 doesn't do anything.
Big Thanks once again!!!! This was really AWESOME!!!!!!!!!!
