We manufacture this US-made wire set which incorporates longer-than stock connectors for easier servicing. The connectors are brown Bakelite, very similar to some German connectors. Brass ends are tightly crimped and rubber holding pieces are included.

See NLA 109 951 00 for our wire set with short black plug connectors.
See 999 701 010 00 for rubber o-rings to organize wires; 4 pieces req'd per engine.
