The correct way to install opt 7 bluetooth Led’s with door assist on a Fiat 500.

The fiats dome light does not provide a positive trigger when the dome light is on. It gives a negative trigger and you can not hard wire into it therefore you will need the schematic I made. The schematic will slow the door assist the constant power it needs without having to hard wire straight to the battery. This eliminates a always constant current draw on the battery . But instead I created the wiring diagram to work with the key on our while the dome light is on. You can find the wiring diagram on my IG at d.w.Lyles.
