So my 92' Civic did not come wired for the MAP sensor. My D15b is running fine other than throwing a code 5(MAP Sensor (Manifold Absolute Pressure) mechanical problem / disconnected piping). For some reason the radiator fan is also not turning on. The MAP sensor I need to wire in has three wires a Yellow/Red, Green/White, and a White wire. I know that the Yellow/Red wire runs to D15(Intake Air Temp), the Green/White wire runs to D22(Sensor Ground) and the White wire runs to D17(MAP Sensor). Can I use different wires out of the spare harness I have? Is my MAP sensor not being hooked up causing my radiator fan to not turn on? I'm only throwing a code 5. After about 10 minutes of running a little bit of steam starts coming from the radiator. I'm assuming this is because my fan isn't coming on.
