Hi guys, I bought a radio remote control for my friend’s lupo at ebay and would like to install it now. Can someone tell me where I find the best + and – in the footroom of the driver’s side without having to dismantle the panels? There are three plugs with many cables behind the cover at the bonnet opener, does any of you know which color + and what mass is? Normal red and brew I somehow didn’t find there. Rather red-brown and so. Thank you sc hon once for your help!!!!!!!!!!!!!!!!
