Ok the rectangle plug that comes of the ECu and goes up in the dash as some wires that match in color but there are 2 that dont. There blue/black and brown/white. What do i do what these? People say just match color to color but they dont all match, the car is a 92 240sx SE motor is a redtop. thanks for the help

You only use about half of those wires. If the colors dont match, leave them alone.

Don't sweat it for now.

If something doesnt work later on, get some FSM's and figure it out. Those extra wires are for the "check connector" or some crap.

Who cares.

Well my problem was that cause the sr and car harness both have sockets i decided to cut of the one on the old harness. When i matched up the colors on the remaining end of the ka harness and the sr harness the wire did not match. Well come to find out i need to match the wires toe the car side of the wiring as the wires change color when they go through the plugs. Does this make sense?
