Instrument Cluster


One of the things that truly does worry me about all this is how to make all the instruments work. The Zilla controller will run the tachometer, IF I can isolate the leads to it, figure out what each one is and plug them in to the hairball correctly. The Zilla can also use the "Check Engine"light (or any other unused light for that matter) to warn of system faults, again IF I can figure it out.


The tough one is going to be the speedometer. The sensor for the speedo is in the trans axle. It sends a signal to the ECU (Electronic Control Unit, the car's computer) which in turn sends a signal to the instrument cluster. Well, the ECU is effectively dead. At least I think so. It's still there, but of the 6 wiring harnesses that were plugged into it, all but one is gone. My hopes that the one remaining cluster of wires contains both the lead in and out for the speedo, AND the unit will work as designed with no input from an engine are slim.

I may end up having to build something that processes and sends the correct signal to the instrument. Stop laughing! Yeah, I'm not so sure I can do it either. I may be left with no other choice than to use an after market speedo. I think you can see why this part worries me.

Thank you for the info. It sounds pretty user friendly. I guess I’ll pick one up for fun.
