Assuming it uses the blue-grommet Duraspark II module, yes. DSI and DSIII modules don't count; California-emissions-equipped vehicles don't count.

Do what you want and I can appreciate wanting the direct-fit (I'm generally the same way) but the fact remains it's likely going to be a while before you find exactly what you want.... you have been warned.

That's a good question....
DSI came about in the mid-70s IIRC (1975 sounds about right) so don't use anything from pre-1977... I seem to recall the DSI modules looking very much the same but my memory of them is hazy and I certainly don't remember the specifics, just avoid it if it's questionable.
DSIII Came out in 1980 *mostly in California vehicles* (and possibly high-altitude configurations but this is another thing I can't be positive on) and EEC-IV came about in 1984.
Best thing I can offer is, yes, the two-plug, blue-grommet box 1977-1983 49-state is what you are looking for, avoid anything else.

Be aware that some models had a tachometer, and some didn't. A harness for a truck that has a factory tach on it will have an extra plug, and the ones that didn't have a tach will not have the extra plug in the harness.
Capiche?

For a proper fit without modifications, you will need a harness from a 1980 - 1983 F100, F150, or Bronco that has an I6 engine. [Except for California models that used Duraspark III] these years still used Duraspark II.
Be aware that some models had a tachometer, and some didn't. A harness for a truck that has a factory tach on it will have an extra plug, and the ones that didn't have a tach will not have the extra plug in the harness.

The wiring harness in my '84 came from a 78, I believe.
Not only that, but nothing is different between a tach and a non-tach version. The only difference between a tach and non-tach equipped truck is the circuit board on the back side of the instrument cluster. The signals are all still there whether you have a tach or not.
My '81 came without a tach, and I simply swapped in an instrument cluster that had one and it worked immediately.

To all: I have a harness off of a 79 F150 I6-300. The problem is, it has a large duraspark connection and a different Gray connection on the module side. I have a 4-pin, 3-pin and a 2-pin plug on my engine harness!!??
