Trying to figure this out. Sr20 swap into a sohc 240.  
My sohc interior plug has no orange wire. The orange wire is the ignition switch. The plug has the orange And black wire, but no solid orange. What do I do? Was this plug re pinned? Or am I missing something.

Also where do u ground the 3 black sr20 Ecu wires. Because the plug doesn’t have the ground wires.

Yes. I used it all the way till I got caught here. I don’t have a solid orange on the sohc plug. Only a orange/black wire.
