An electronic engine control system test analyzer using a basic test switching control box connectable to a standard digital volt/ohm meter or oscilloscope not just a special unit that a specific model and year car uses. It is a relatively small versatile test switching control box useable with substantially any modern day electronic engine control system. Adaptability from vehicle to vehicle electronic control system is accomplished via change of wire harnesses specific to each different vehicle system without changing the test switching control box. The test switching control box is a much less expensive unit than its counterpart dedicated to a specific make model and vintage vehicle and is in modular form that can be updated to greater numbers of test positions from time to time.
