I have been doing some searching but nothing that really helps with the information that I am finding in my Ford service manual.
From the service manual I am finding that the left front speaker is wired differently then all of the rest.
The left front speaker has Pin#1 is + and Pin#2 is -
Meanwhile right front and both rears have Pin#1 as - and Pin#2 as +
With all of this information I am finding that my adapters are pinned correctly for 3 of the speakers but not the 4th.
Can someone confirm that the front speakers are different part #'s
