When I installed my Pioneer deck a while back I used the included Honda antenna adapter to plug in the screwy OE antenna wire to the back of the new deck. That adapter had a blue wire coming off of it that I did nothing with. Ever since the install my radio reception has been for s#$t. I usually listen to satellite radio so it isn't big deal. However, i would like to know, was I supposed to do something with that blue wire? If I connected to something would my radio reception improve? TIA guys

 

IIRC that blue just connects to the antenna wire off of the radio adaptor harness...

don't quote me on that though...
