Default Tachs are not the same....?

So I thought that all tachs are the same from ranger-explorer 4cyl-8cyl.

They are NOT the same! I got a tach cluster from the boneyard today as I am waiting for the white one to come, I got it from a 96 explorer.

Upon driving this afternoon, the tach pegged over and hit the speedo!

It shows the same idle, but while driving it is very off, at 70 it was showing 3,200. Normal for my truck at 70 is 2,200.

I also thought this when I put my cluster into my dads truck, when revved up the sound of the motor did not seemed like it matched the tach.

I think that I got a tach from a v8 explorer which is why its off.

My dad got mine from the v6, he has a 4cyl. I think that is why his is off.

Anybody have any insight as to if there is an adjustment on the tach...? Im sure ford did not make different tachs for different engines, there must be an adjustment....?

ok, so here it is. I found that there is a yellow dial on the side of the tach, turning this dial counter clock-wise must be the setting for 6cyl. It was turned to the right (clockwise) thus being for v8 - explorers.

From what I have found on the web, #8 pin from the 10 pin connector needs to be put into #16 in the 16 pin connector for 4 cyl. motors. The tach must be turned to the 6cyl mode.

I will check this tomaro on my dads truck.

Here is a pic of the dial:

I know on the older F-Series, the V8's had an extra wire, compared to the I6 trucks, that led to the tach. Maybe it's still the same?

Edit* Interesting that there's a dial on the tach to switch between the engines.
