Do you have a recommended pull-down resistor size/spec for what will be battery connected inputs? It's an old classic car and I want to keep the switch gear original so I don't think I can switch the inputs between +ve and -ve.

That solves a problem! Just need wiper motor specific outputs now.
As of June 2020, all PDM 15 and PDM25s have a week pull down resistors installed internally of 1Mohm. If fast input switching is required, it is still recommended to install an external pull down resistor.
Hi Dave,
For battery connected switches, please use pull-down resistors of a value between 5k -10k Ohms.
Alternatively, for ground connected switches you can use pull up resistors.
To remove the need for resistors all together, switches that switch between ground and 12V can be used. The switch panels in our store work in this way.
Regards,
George
