Fitting the radio plug into aftermarket head unit
 

Hi Peoples I have installed my Pioneer AVH-P8450BT into my Toyota 86 and I have ran into the issue of the Radio Arial plug, what have people done to make this fit an aftermarket deck as the factory unit has a plastic connector there and obviously its not compatible.

Does your 86's antenna plug look exactly like the one shown here? (leftmost connector; picture is from this thread)

If so, see this post. I have the AI LX-8 adapters (equivalent to Metra 40-LX11) available, and will ship to Oz.
