'94 Gauge Cluster Swap

'94 2.3L Gauge Cluster Swap

I'm sure this topic has been covered but I've searched for an hour both on this site and Google and I'm still with question.
I have an '94 w/o tach cluster and I picked up a '94 tach cluster but most of the pins are different between the two.
Is there any info on swapping the pins to make it work?
Also, there's no teach signal in the harness. Where do I pick up a tach signal?

Did the cluster you grabbed come from another 4cyl truck?

The harness should have a tach signal wire in it. Kinda like how your truck is already mostly wired for power doors and fog lights.

It's been years ago, but IIRC, you can pull your cluster apart and replace delete panel with a tach, as long as it came from a truck with the same number of cylinders.

Both were 4-cylinder trucks. But mine has gauges on both sides and there's no tach signal in my harness.

Where do I find the tach signal? There are two wires left out of my harness for tach signal. Anyone know?

$ cyl tach wiring

Hi,

According to Ford's 1994 EVTM (Electrical and Vacuum Troubleshooting Manual) the 4 cylinder tach only uses three wires- in the "sport" (ie with tachometer) they are as follows:

red/yellow on connector C250 #640 (pin 14) 12v from fuse panel
black/white ground on connector C250 (pin 2)
tan/yellow to ignition system on connector C250 from ignition (PCM and other ignition-related components) pin 8

Apparently only the six cylinder engines have a separate signal wire, as the four cylinder says "NOT USED."

You may wish to see if you can find a copy of the EVTM page so you can see what I am talking about, but hope this gives you some direction....

BSG

PS the title should read 4 cylinder (damn keyboard....)

If the clusters are actually from the same year, there should be no difference between the tach and non-tach models. A tach cluster going into a non-tach truck of the same model year is plug and play.

The tach wire is present in all models. They don't make a different wire harness for tach and non-tach models.

There is a wiring difference between the 92 and 93 model years but as far as I know, there is no difference between 93 and 94.
