These harnesses have not changed since day one.
The Valeo connector is prone to overheating and failing so here is the deal.
Please review this info:
Cut off the Valeo 4-position fan connector leaving as much wire as possible.
Trim back the black covering on the black/yellow/green wires by 2.5"
Place the green wire through one blue seal supplied.
Place the yellow wire through one blue seal supplied.
Place the two black wires through one blue seal supplied.
Strip the ends of the green, yellow and two black wires by 3/16".
Using a pair of 'B' crimpers or fine tip pliers crimp the wires onto the supplied terminals as shown.
Using a pair of round crimpers or fine tip pliers crimp the back terminal ears around the blue seals as shown.
Solder the terminals as shown. Do no get solder anywhere other than on the crimp area as shown.
Apply some supplied silicone grease to the seals and inlets of the wires to help seal and insertion.
Insert the black wire(s) into channel 'C' of the supplied connector.
Insert the green wire into channel 'B' of the supplied connector.
Insert the yellow wire into channel 'A' of the supplied connector.
Insert the TPA / black terminal lock on the backside of the connector
The yellow and green wires can be reversed as it is a combination of both having power that provides high fan function.
