How to test switches with new wiring harness

Roger Williams

Hello All

I am nearly finished installing a new wiring harness in my Austin Cooper S. I have tested items such as the horn, wipers, heater blower, lights, etc. using my 12V bench battery so I know they work independent of the wiring harness.

Once the switches on the dash and the steering column are connected I would like to re-test.

So... my question is .... how/can do I do that?

The battery is not in the car.
The engine is not in the car.
