2.3 to 4.0 dash harness

[Dprocks100]

Swapping in a 4.0 to my 91 2.3 ranger. My question is if the dash harness connector (big white connector) is the same on all engines for my year or if the 2.9 and 4.0 differ from my 2.3 on the dash side. I can find that the 2.9 and 4.0 interchange but not solid info on the 2.3. I assume it does, correct? My EVTM manual comes next week so cant look it up in it.

It's fairly unlikely that they'd have changed anything on that connector for the 2.3 if the 2.9 and 4.0 were the same.

The only thing that I can think of being even remotely engine-specific on that connector is the tach signal which is still carried on the same wire. It's just a different signal requiring a different setting to read correctly.

It's all the same. You will probably have to change the ground pin for the tach at the cluster to make it read right, that's the worst of it.
