Ive only got a wiring diagram for the VP, but Im pretty sure that they are the same as VN.It shows that the Pink/white wire goes from the cooling fan relay to fuse number 9.Fuse number 9 also goes to the heater fan switch via a Pink/white wire too.
There is a pink and white wire on my VN diagram at location 37 from the pin 86 on the relay and joins the pink and white wire (i pretty sure that the wire color) that run from fuse 8, [Cooling fan relay, A/C compressor, heated rear window relay] to the blower motor switch.
