Description

This is functional plug to use in place of the one coming from lambda/oxygen sensor wires on a SWM Superdual X motorcycle.

Most likely many other motorcycles are using such 4-pin connectors, AI identified it as "Sumitomo 090 Series 4-Pin Automotive Connector". I wanted to try some things with fuel injection and did not have possibility to buy/scavenge some stock connector, but needed it "today", so modelled and 3d printed one.

The crimp terminals are roughly 4mm x 2.5mm.

The details are quite fine, so ideally 0.2mm nozzle would be better, but it worked for me printed with 0.4mm nozzle, just line width reduced to 0.25mm.
