Discussion and questions related to the course Professional Motorsport Wiring Harness Construction
I am looking for sample wiring harness design to train my self.
As I finished the professional motorsport wiring harness course. Unfortunately I don't have any project car to start my design.
Can I get some help.
Sure, take a typical project. Let's say connect a standalone ECU (you choose the ECU) to a Honda K20 (or any other engine you would find typical). Just like any project, you'll need to find the pinout documentation for the ECU, learn what requirements/limitations it has for voltage / grounds. Then you need to find documentation on sensors / connectors. Create a spreadsheet with all the connections, and a Layout drawing with the lengths between each connection and how they are bundled.
So what you know:
12V permanent Power
12V Key-on Power
Engine Crank Sensor
Engine Intake Cam Sensor
Engine Exhaust Cam Sensor
Engine Coolant Temp Sensor
Engine MAP Sensor
Engine Air Temp Sensor
Engine Throttle Position Sensor
Variable Cam Timing Valve
Fuel Pump Relay
Coils 1 - 4
Injectors 1 - 4
Possible Alternator Control?
Possible Knock Input?
Possible Sequential Gearbox Position Input?
Probably need a connection for the Tuning Laptop
Perhaps some outputs for a tach, or CAN output for a racing dash / logger.
Assume the ECU wants to go under the dash on the passenger side of the vehicle.
Thanks a lot David.
