Thank you very much Lizzie and AZKen. Seems that I wired correct
Until my GMC project I have no idea about wiring and power but I learned a lot and it was fun. Some brainwork. And thanks to 6066gmc site for a lot of information.
At the moment the things I have tested are ok. Headlights, ignition, wiper, heater.
One question about the fuse. The panel and lights have a 3A fuse. Is it ok to use a 3.15A?
Many greetings
Tom
