I switched my motor from a D15B8 to B18C. We had finished the wirings but then two lights were turning on (seat belt light and e-brake), on the gauge cluster while the car is off. Some people said that it was the cluster but I swapped out the cluster to my stock one and the lights still come on, so its not the cluster. I then swapped the ECU to my old one too, and the lights are still on. I am currently running my stock wiring harness.
Its not the Cluster or ECU.
I don't get it, the lights weren't coming on before, why would they come on now?
