It doesn't. Here's what you need:
The connector has latches on the sides -- it flips open so you can move the
pins.
The rest is from one of my old posts. The ground for the oil buzzer is not
as simple as I've presented it here -- if you do it this way you will never
see an oil light above 2000 rpm. There are various ways to deal with that,
the simplest being to remove the circuit board in the speedo and jumper so
the sender feeds straight through. I hope other folks will sort this out
for you, I have no time right now. I'll look back in on Monday or
thereabouts, we're about to head to church for Pascha ("Greek Easter") in a
little while.

Here's a circular list. First column is where the wire used to be in the
connector. Second is where it goes. Third is where the displaced wire
needs to go. It's convenient to know that immediately when you have wires
squirming all about.
80-84 85+ which goes to 85+
3 1 none (1 was vacant)
4 2 3 (cut and splice as below)
5 3 1
Old terminal 5 goes to ground. It is jumpered inside the old panel to old
terminal 2, which provides a ground for the 4-way flasher's pilot
light. No, I can't imagine why they did it that way. (!) Anyway, splice
the lead that used to go to pin two into the one that used to go to pin 5,
and run the pair to pin 3.
None None 2
7 5 3 (see previous note)
6 6 6
8 7 5
9 8 7
Tach 9 8
14 10 13
13 11 14
x 12 none (High oil pressure except '85
which has none. Ground to keep buzzer from going off, or make more
elaborate arrangements)
10 13 11
11 14 10
Old pin 12 goes to a connector under the dash and stops. You can splice in
your tach wire and use this female terminal to go into pin 9 (it was the
glow plug indicator for Diesels).
