JPT55 connector, often referred as "Motronic" connector, used on several engines (audi, porsche, etc...).
Useful when maintaining original harness for a plug-and-play installation (beware, it can be more problematic than it seems). Either used as one end of an EC36wire - JPT55 adapter cable or the genboard v3.x directly wired to this connector (instead of EC36-PCB).
