2000 GT Instrument Cluster swap
 

I have a 2000 GT cluster and want to upgrade my 94 with it. I need the wiring diagrams for the both of them. I figure it should be pretty strait forward from there.

It won't be an easy swap as you will need to upgrade the PCM from EEC-IV to EEC-V to drive the speedometer, tachometer, coolant temp, MIL, and a few other warning lights.

Here is the 1994 cluster wiring diagram:

Note that only the MIL, the auto-tranny O/D lamps and the tach are controlled by the PCM--and all directly controlled at that.


Here is the 2000 cluster wiring diagram.

On the 2000 the speedometer, tach, ECT, MIL, O/D indicator and other function are provided as digital data over the Multiplex Communication Network. In later models this became called thethe SCP (Standard Corporate Protocol) bus--and is in fact the OBD2 data bus.

A microprocessor in the cluster reads the digital data and then drives the gauges, all of which are just identical servo motors; not "real" gauges at all. Here's a shot of the backside of an '01 cluster with the electronics removed.

You said that so gentle; like you didn't know it was going to ruin his day, lol.

Not a bad thing at all just something else to make me find a 1995 Bronco or F-150 with a 302 to grab its wiring harnesses and PCM. They are EEC-V and OBD-II and that should do the trick.

shorting out
 

WHAT can cause a cluster to stop working after 10 or 15 miles ?? Loss of ground ? How do you track that down ?


Seems to just be the fuel, tack and speed guages shorting out.

any chance someone could help me out with the wiring diagram of the 2008 mustang instrument cluster or guide me in the right direction on installing new digital speedometer and tachometer??? ive been looking for days and found this forum in hopes of a solution or some kinda help.....ive googled and came up with nothing time after time grrrrr HELLPPP PLEASE

Maybe, hopefully.... I suggest though that you re-post over in the "other" 4.6 section (relevant to 2005-10 model years). Highly unlikely anybody in this section will have much knowledge on this.

if you are swapping clusters, whether new or used, it will need to be programmed. Using a ford IDS or similar you will have to suck out info from old one, install new one and download info on to it. Its not plug and play
