Good evening, my car is causing me some problems at the moment, which I try to identify more precisely. More precisely, my ventilation no longer works. Before I change any parts, I would like to check the ventilation motor in which I give electricity to the part. Up to the plug I have already fought myself. Only how is it going on now? I have a plus and a minus pole under the hood. The battery is in the trunk. clamp both poles under the hood and at the other ends two long cables which I hold again to the + and the – pole of the plug? I just don’t know what I can use for cables. I think telephone cables do not go because of the smaller cross-section but also does not go too thick because the plug is not very large and somehow I have to hit the pins.
