From 240sx.org FAQ.

"Yellow/Red --Tach
Yellow/Green--Speedometor
Orange--Ignition start
Black---Ground
Blue/Black---Water temp sensor

There will be some wires left over. These are for the SOHC's diagnostic plug, and are unnecessary. Please note: Your car will NOT be able to hook up to a CONSULT tool."

From my experience, engine harness had 12 wires and body harness under the dash had 16. But 6 wires on the dash side and 2 wires from engine side did not match any wires on each sides. I left them for now and am searching for their matches.
