Hey, I rewired my JDM one-pieces using the Teg Tip, but I ran into a small problem–I cut the fog red wire too short, which made it nearly impossible to connect it to the black defrost wire.
Solution: I took some basic speaker wire, folded and twisted it around the cut fog wire, easily extending it to the defrost wire.
I know it’s simple, but for the less than mechanically inclined it may be helpful.
