In addition to the cover, it is important that you have the small piece of clip-on trim installed on the fender edge above the jump post.
It appears that the design of the fender is such that water (rain or wash) runs down the edge of the fender and spills off directly onto the jump post area. This is especially bad when the water contains soap. The little inconspicuous piece of trim makes the water fall off at a different place, greatly reducing the corrosion of the wires at the jump post (and the coil on later cars).
There should also be a piece on the left fender for later cars.
WallyP: Thank you! That is very good to know. I will add that little piece of insulation to my next order list. I guess I am lucky, in that there was no corrosion on the jump post and associated wiring. As well, the 14-pin connector had very little corrosion.
No problem, however, the slotted groove along the top of the cover is suppose to slip over the lip of the fender. You will also need a piece of crip-rubber-molding to put just above the cover, to keep rain water from running down behind the cover.
Not the best picture, but you can see the cover and molding on my 84.
The Deputy: Aha! I wondered what that little lip was for. I am working on finding a piece of the insulation molding to go on the fender edge.
Good photo!
Seth, I think you are going to find that you need to disconnect the wires coming into the jump post because I have found it common for them to have been re-arranged in such a way as to have the last loop in the main battery cable outside of the bundle rather than around it. That's why your new cover does not fit like it is supposed to. Disconnect the battery first, then redo the wire bundle at the jump post.
I'll add a recommendation that you use a strip of electrical tape along the lip of the fender where the cover fits, to eliminate the chance of paint wear. Clean with wax/silicone remover so the tape will stick. You'll have the tape hidden by the cover when installed, and no scarring of the paint later on.
Stoooopid stuff, but it adds up later as you cherish the condition of your car more.
Jerry Feather: Thanks for the heads-up! I will disassemble the wiring at the jump post and try to reconfigure it. I did notice that one of the larger wires at the jump post was coiled around the 14-pin connector cable assembly 2-3 times. I don't know if that is correct or not. It has definitely taken a set.
I will work with all of it and see how it turns out.
