I just changed out my KA24E for a DE from a 1993, and it runs great and everything works except my tach. I was going to just wait until the RB20 showed up but at $2.38 a gallon with my other vehicle-a suburban...well it wasn't working. When I installed the engine I used the De harness and ecu, and then cut and spliced my dash plug to the DE harness and matched the colors. I have 2 wires left coming out of the ecu, and 6 wires left from the dash. None of the colors match up, anyone know which goes to what?
