Scania aux in

skinhead:
I took out a switch blank and fit one of these to it,
ebay.co.uk/itm/3-5mm-Mini-S … Sw9N1Vjo~U
Then got one of these, cut the jackplug off and soldered the wires to the socket,
ebay.co.uk/itm/Aux-In-Input … Swo4pYfxWn
Scania wanted £50 for the same thing.

Can i do the same as this in a daf cf ?
