Have a 91 CRX DX. Killed the D15B2 that came in it last week. Picked up at 89 Si and began to do that swap. Only after getting the new D16A6 in the car did I notice the wiring harnesses were different. Looked up the DPFI to MPFI conversion. Have done everything to what I beleive is correct. When I turn the key on, the dash buzzes and the check engine light comes on. So I disconnected the Injector harness and the buzzing stops. Got some wire and was going through checking pin to pin to see what was causing my problem. The yellow/black wires, when connected to the resistor box makes my check engine light come on, and the dash buzz. Any ideas as to why it is doing this?
