Description
Description
Need to replace old broken defroster in my 240z but can not find any that are still working. Also needed to add switch to fog lights so figured willcombine the 2 plus add couple other functions to the controller and solve everything with single module to have following:
- defroster with auto shutoff 10 minutes
- fog switch dual filament one will be used as DRL.
auto shutoff with ignition switch
- clock
- thermometer (interior)
- voltage monitor
- may add power usage monitor
