Wire Harness

Im parting out my trucks (74 and 83), and one member was wanting the brake light harness but his truck is a 78 and I don't know which harness he needs seeing as the two differnt years looks totally different, anyone have a clue which year he needs?
Thanks for the help guys!

Re: Wire Harness

73-78 uses the glass fuses and 79-87 uses the spade but both work with a little work

Re: Wire Harness

So Im going to guess that the harness is the same from 73-78 and changed in 79 and stayed the same till 87?
