VW used to sell those the way your picture shows them but decided that no one could crimp them to a wire properly
. Now you get an 18" piece of wire with a terminal crimped on each end for $4 - $7 per wire (cut the wire in half and butt connector to your old harness)
! The wires can be purchased in different gauges... .5, 1.0, 3.0mm. I'd be headed to NAPA to see Bryan67.
Wait... the same person who is not capable of crimping a terminal end is capable of crimping a butt connector?
I'm failing on seeing the logic here. Maybe the logic is that instead of selling a 75 cent terminal, they can sell a 7 dollar piece of wire with 2 terminals.
I always solder everything... not doubt if there's a good connection or not!
