    E30 M3 S50 swap what wires stay and what GO?

    I've got a buyer for the blown S14 and I don't know what I can let him take as far as wires in the engine bay/ inside the fire wall. Do the adapters you can buy from tree house racing plug into all the S14 plugs going to different sensors??

        You can let him take everything attached to the motor. You only need the plug going right from the firewall.

          I'm going to need one, soon. How long will it take you to make me one and have it shipped out?

            the big harness with a bunch of wires going various plugs in attached to the engine seems to double back and connect the the harness going through the fire wall to the interior and to the fuse box. Basically there are about 5 or more wires that seem to go to the ecu that are coming form the engine harness. Can I cut these or do i need to follow them back to the ecu?

                Do you have a bentley?? Just follow it if you do. A regular e30 bentley cover m20 engine removal: it should be very similar for your engine.

                You shouldn't have to "cut" anything.

                  what about the wires going into the fuse box? I've got everything lose but those. I took the cover off the top of the box and it looks like they are hard wired in.

                    The engine harness will come out entirely with end connectors and all. If you have to cut anything....your fucked or your trying to remove the wrong harness.
                    You don't need the wires to the fuse box unless your doing something weird with the car.
                    I also took the o2 sensor wires and sensor for good measure.
