    Hi guys, I got a 1991 Japan import M tech with auto to 5 spd swap car with sport selector, no cruise control
    The reverse light is not working so I took the center console out and this is what I see

    1 is both, GREEN/BLACK wire and BLUE/YELLOW wire spliced and goes to wire from manual
    2 is BLUE/WHITE going to another wire from manual

    There is no connector to reconnect so I'm totally lost
    Since this is a Japan import I don't think there is much info out there

    Can anyone please help me?

    Thank you!

    Reviving this a little as I (still) have a similar problem to Xelo:
    I also have a euro car with the "sport selector" knob thing, no cruise control.
    The car runs and drives fine, but the Check Engine light is constantly on (in the picture Xelo posted, it's the one with the exclamation mark) in it.
    I unplug the transmission conputer in the trunk, it turns off, but then it doesn't even come on when i get in the car and put the key in the "ON" position. The other interesting thing is that the stomp test does not work, ever.

    Is there some other wiring we have to take care of?
    Other thing to note is that these cars have a 6 pin throttle position sensor, not the usual 3 pin.

    If your shift boot is still pliable, you can use the tips of needle nose pliers to stretch open the harness hole in the boot. The backup light harness plug will pass through. If your hoot is old and crusty, this method may tear it. Use a pin tool to remove the plastic plug, pass wires through boot and then reinstall plug.

    Thanks, it worked. Auto light went off, but check engine remained... I'm gonna investigate that later, though :).

    I have another question for you guys, so please bear with me on this one: got the OE wiring for the backup switch on the manual gearbox, but:
    1) how do I get it into the interior compartment ? is it through the gearlever rubber sleeve ? If so, how, that thing has a very tiny hole, the wiring has connections on already - i don't think it's supposed to get them off, route it through the rubber sleeve and the re-fit the connections ?

    This is the hole in the shifter sleeve: https://ibb.co/TLyNFnt
    This is the wiring: https://ibb.co/6Nz6Ny1

    If not, is there another hole I can route it through and haven't noticed yet ?


    2) i've found a wiring with matching connector inside the dash (long white connector), is that the proper connection for the backup switch on the gearbox ?

    For the sport version, yeah there's a computer. But not for the majority of the autos.

    I'd just unplug the computer and/or remove the bulb. It isn't doing anything.

    Yes, I do. Or the car did.

    There is some confusion about this transmission computer, someone even showed me the part itself. Some others say it does not exist.... I'm really into doubts here.
    I have to say I'm located in Europe, car was a German version, if that matters for some reason.

    Trans light? E30's don't have a transmission computer. Do you have the rare version with the "sport mode" selector?

    Hi guys,

    I've bought an E30 which had the auto swapped.
    Works OK, but I have trans light on and also check engine flashes. Will this re-wiring help me with that too or do I need to look elsewhere ? And if so, where ?

    Thanks in advance.

    Sooo I've dug through under the dash for a while now and can't find the "Blue/Yellow" to "Green/Black" connection.

    That doesn't handle cruise control does it?

    Is it possible Euro models may be different or have it somewhere else? I can't seem to find a connector with wires that may be the euro equivalent either.

    Bump for this! Just did it on my 5 speed swap and everything functions accordingly. I was having a bit of a problem at first but it was because my brake pedal and clutch switch bracket needed to be adjusted. Now I just need to figure out my hanging revs.

    After reading this and following up with my friend Derek, it took 5 mins to get the car started!!!! No Cutting, just plug and play. Just like the original post- your are going to disconnect the added auto harness- I left the 2 ground wire connected.. figured they werent gonna do anything.

    *** USE THE OPs PICS for REFERENCE to find the harness and location***

    Description:

    The Auto Harness has 5 wires on it- 2 Brown, 1 Black with yellow stripe-connected to another black wire with yellow stripe via connector, 1 black( connected to ignition switch, 1 green with black stripe( this one may vary- older models might have 2)-connected to blue wire with brown stripe.

    1st UNDO the AUTO HARNESS:

    1) Unplug Blue wire with brown stripe connected to Green wire with black stripe.

    2) UNplug black wire with YELLOW stripe connected to black wire with YELLOW stripe

    3) Unplug black wire from ignition switch.

    Now time time to make it all WORK:

    1) Plug in black wire with YELLOW stripe into ignition switch where u pulled the black wire.

    2) Unplug the harness that is plugged into the reverse plug-( This is located by the hole where the shifter comes thru)- then plug in your reverse plug from the trans into the plug that you just disconnected,.

    3) Plug in the White Plug and is deleted to itself to the clutch switch on the pedal ( The White plug is the one that is deleted to its self with blue wire with red stripe)

    YOU are now DONE!! Start your car!!

    Everything works on my 91 vert, back up lights and cruise control good to go!!

    Just in case photobucket goes down again, I saved the photos and rehosted them on flickr. Enjoy

    and here are some pictures.

    these brown wires go to ground.

    one of your clutch sensors capped off.

    by the trans, bottom right is the manual hookup

    as for that black green wire that goes up by the ecu, its to the left of it. you will see it. it connects to the blue red.

    in all reality you can more than likely hook up your clutch switches any way you like, but i remember the location of the switches put them in their spots.

    any questions, i'd be happy to answer.
