Hello everyone. For the sake of conversation, let's assume someone is pulling the 3.0l V6 out of a 2005 Ranger Edge and installing any other engine of their choice. The engine of choice doesn't matter as it will in no way be connected to any of the stock Ranger systems, other than the ignition switch. It could be a carbureted engine or it could be a modern engine with a stand-alone harness.
At this point, what factory systems keep working?
The fuel level gauge is the only gauge in the instrument cluster that I believe will continue to work as normal as the other gauges will have no input signal.
The head lights, brake lights, marker lights, and turn signals should work as normal.
The dome light should work as normal with the switch on the dash as well as with the doors opening/closing.
The horn and radio should work as normal.
The heater system should work as normal, assuming the engine is plumbed into the heater core.
The A/C system is questionable to me. If the wires to the factory A/C compressor were used to turn on the new A/C compressor on the new engine, I believe the A/C system should work as normal, but again, that is questionable to me. Refrigerant compatibility is something to be considered, but not for this question.
I believe the fuel pump would work as normal. When the key is turned on, the fuel pump should run and stay running with the key in the ON position. Fuel pressure compatibility with the new engine is something that needs to be considered, but isn't important for this question. Return line or no return line is also something that needs to be considered, but not for this question.
Power windows, locks, and mirrors should work as normal.
Airbag system should work as normal.
That's all I can think of right now. Anyone notice anything that I have overlooked? I'd appreciate input from anyone that wants to offer any suggestions or confirmation of my assumptions. Thanks!
