Default What is this plug and wire for?

This purple one isn't the starter wire, my starter wire was labeled from the guy who trimmed my harness.

They both are in the same loom and it has a heat reflective tape on it, if that helps.





TIA

Do you realize how many connectors are that style plug?

What is it next to or where was it located?

Looks like the crankshaft position sensor. Should have a light green, yellow, and dark blue/white stripe wires attached.

That is for sure the crank postion sensor harness. It's easier to remove the two 13mm bolts holding the starter in place and expose the sensor connector. It is against the block behind the starter

Maybe for the starter? The starter has an 8mm bolt on it for the wire coming from the ignition. I think it's purple. The red wire goes to the big terminal. There will also be a black wire from that same loom. It has a funny shaped end on it that looks too long. It needs to be grounded to the block.
