I'm trying to utilize the factory instrument cluster after an engine build/carb swap. It's a 1995 Corvette with a carbureted LT1. No emissions or vacuum accessories are on the engine. The ECU/powertrain computer has been removed as well. The transmission is a built 4L60E controlled by a US Shift Quick 4 controller. This controller has a speedo output wire.
I have been able to get the tach, oil pressure, oil temp and voltage working. Water temp and speedo are throwing me for a loop. I have schematics of the water temp sensor to the ECU but nothing else. I can not find any schematics regarding the instrument cluster.
Does anyone know what the water temp input wire color is? Is the cluster input a voltage value? Or Ohms direct from sensor?
Does anyone know the speedo wire input color?
Thank you in advance for any information sent my way.
