instrument cluster

Question, could I take a instrument cluster that has the tach and replace the current one in my 89 f250. If so would I have to run new wiring or would it be a direct swap?

88 to 91 are direct swaps for tach clusters. 87 cluster will work but you will need to change the oil sending unit to a 87 for the oil gauge to work properly.

I did this swap in my '91 bronco going from the non-tach instrument cluster to one that has the tach. Took about 45 minutes, and everything worked!

I would recommend staying with the same year, if possible, i.e., 89 to 89 in your case.

Not an expert on this one, but I know on my fox body cougar, you had to match engine cylinders or else you'd have to rewire for the tach.

That is, the 6 and 8 cylinder trucks may not have the same tach wiring.

Surely someone else will confirm or correct as needed.

If by chance you do have to "reprogram" the tach, its a simple as removing or adding a ground from the tach gauge Labled as "6/8" other pins are power,ground and tach.
