Cab wire harness part #?

[Gary Lewis]

Myrl - Thanks! I created a page to capture the wiring harnesses: Documentation/Electrical/Wiring Harnesses/Wiring Harnesses, but to this point only have the cab (instrument panel to dash panel) harness included as I had no idea that there are as many different harnii as there are.

But if I've missed some please let me know.

And WOW! I had no idea there were that many different cab (instrument panel to dash panel) harnesses for the F-Series trucks:

1980: 4 With & without gauges and with & without aux tank

1981: 4 With & without gauges and with & without aux tank

1982: 4 With & without gauges and with & without aux tank

1983: 6 With & without gauges and with & without aux tank, diesel, and 460 hot fuel handling

1984: 6 With & without gauges and with & without aux tank, diesel, and 460 hot fuel handling

1985: 18 I can't get my head around all of the changes

1986: 8

WOW

We know the 80 had different wire pin out but I wonder if you could use 81/84 (less the diesel's & hot fuel handling) for a swap or upgrade (aux tank or gauges)?

For 83/84 the diesel & HFH did the trucks come with gauges only?

Other wise you would have 8 different harnesses for them years if I count right.

I guess I was lucky I had an almost match for my harness swap in the 81.

Both had gauges and 1 with & 1 without aux tank, I used the aux tank harness.

Yes, I think the diesels and 460's must have come with gauges, although I've not seen that in other documentation.

Probably the reason for 18 in 1985 was the mid year introduction of the EFI 5.0L, that is at least 4 if not more right there single vs dual tanks, then if you add w and w/o gauges to those 4 it makes 8 there alone. Since the AC systems were a piggyback harness that plugs into the basic heater only harness it will be a separate PN.

This is most likely why the change in 1987 to separate dash and front harnesses. From what I remember my 1977 had molded rubber plugs at the firewall for lights & horn and then one for the engine including the DS-II system. I have never understood why Ford went to the single combined harness in 1980.

WOW!!! Thank you Gary, this is awesome! I was unable to go to the yard yesterday, but today it’s a plan. If I am successful at pulling two harnii I will try to see what the main difference might be between gas and diesel.

I can say that I have never seen a diesel with idiot lights. I have never seen a single tank diesel either. I can also say that 83/84 diesels lacked the tachometer circuit option. I’m guessing early 85 lacked it also given the note “From 2/85” on one of the diesel ones.

***Thank You for all of the work you put into this!***

1985 was a confusing year. But compare it to '86. There were many changes. And, they dropped the idiot lights in '86 and made the gauges standard, which really made things a lot more simple.

Jonathan - You are welcome. I realized that all the harnii appear to have "Wiring Assy" in the title, which gave me a way to find them. But I had no idea there were so many kinds of harnii, nor so many within each kind.
