Partnumber 2958568!
The partnumber was on the box. After open it up it's an engine harness. Partnumber tag on harness shows 2958569. The white connector goes to bulkhead connector and the other connector's goes to ECU unit, ballast resistor, oil presure switch, temp sending unit, alternator and choke I think.
Box shows 270 indicatio February of 1970. Mid year intro of something?
