I have a 1989 325i BMW. I have removed the instrument panel to replace the batteries. I have two wires that plug into the green module socket that I did not mark to reinstall. One is a flat white wire coming from the computer module and the other is a blue and yellow stripe wire. There are two options for the blue and yellow stripe wire and five options for the white wire. Can you help me locate the correct pin socket for each of these wires? Thanks, Joe

Hello and welcome to JustAnswer BMW,My name is XXXXX XXXXX it will be my pleasure to assist you today.
do you have the last 7 digits of the vin available?
Steve, I am not able to provide the VIN at this time.
Will you be able to provide it later, or do you want me to look it up manually?
Steve, I am traveling and not able to provide this information until Sunday.
Please provide the vin then, and also let me know how many pins are in the connector you are referring to. Also if there is any stripe on the white wire.
Steve, I will take a picture of the green socket on the back of the cluster, provide the VIN, and recheck the white wire. Thanks, Joe
Ok please post the info then. Thanks.
Steve, The VIN # XXXXX XXXXX I have 2 pictures of the greeen socket so you can see the layout of the pins, but cannot attach to this email. Please advise on getting pics to you. Thanks, Joe
there should be a paper clip or tree icon that will allow you to upload an image
otherwise you can upload them to a file sharing or photo sharing site and then post the link here
or, if you know how to read wiring diagrams I can simply provide those and you can work from them.
let me know
Steve, I have the shop manual and could not really decipher the diagrams. I am trying to get the pics to you.
Steve, I needed to use Foxfire since Safari does not support the graphic upload toolbar. Please find the pic of the green socket connector. Thanks for bearing with me on the technical link. Joe
I will review and let you know what other info I need
Steve, The white wire (it is actually yellow now that I have looked at it more closely) running from the glove box that I referred to couldn't be for the green socket. It does not have enough lead to make it. It does however have a plug (male) that looks like it could fit into one of the green socket outlets. The one on the top left if you are looking at the picture. Also, I have discovered a square plug with two male prongs on the glove box side. It could reach to the instrument panel. It has one brown lead and one lead with red/with yellow stripe. Also, just to repeat that this whole inquiry started with my replacing the instrument panel battery. Thanks, Joe
I am having a really hard time following here.
Can you please let me know where on the back of the cluster this connector is and how many pins it has. Also, exactly the colors of the wires you are needing to hook up. And, of these wires, if you have identical ones, where they are plugged into (what connector and what pin #).
The green connector is at the TACH on the panel. It has seven pins. The are arranged (as you look at the photo) TACH on the right with three pins consectively from left to right along the top a space and a pin pin-pin-pin-space-pin (top row- left to right, looking at photo)pin- ----------- pin (second row- left to right, looking at photo)---------------pin (thir row- left to right, looking at photo). NONE OF LEAD WIRES ARE IDENTICAL. FROM WHAT I CAN UNDERSTAND FROM THE BENTLEY SHOP MANUAL- I AM LOOKING TO HOOK UP THE BLUE/YELLOW STRIPE WIRE and maybe another wire that is referred to as flat white wire coming from glove box area. There is no flat white wire coming from glove box. There is a square plug with a brown wire and a red/yellow stripe wire coming from glove box.
Steve, I have confused one aspect of what I just emailed you. The green socket feeds the SPEED guage not the tack. Forget the black square plug. The plug is too large to fit into any of the sockets on the instrument panel. I just tried to match them up. So, at this point unless you tell me otherwise. I think the only wire to plug into the green socket is the blue/yellow stripe. It will fit into any of the pins on the right side of the green socket (i.e. top/middle/bottom). Sorry for the confusion in the last email. Jet lag man, I just got back from the UK and not back on USA time. Thanks, Joe
the factory wiring diagram does not show a 7 pin connector.
can you tell me what color the other wires in this connector are?
Steve, http://www.beckerelectronics.com/SIboard/Step_6.html If you go to this link, you will see the green connector. I don't know what to think on the factory diagram not showing a 7 pin connector. I have what is shown in step 6 of the Becker electronics SI board swap out.l The only wire that looks to go to the green socket is the blue/with yellow stripe wire. It has a lead that will fit into one of the pins. There does not seem to be any other wires. The Becker directions refer to a black socket. I do not have this. I tried to dicipher the wiring diagram in Bentley. It does not show this wire in the diagram on page 48 or 49. Thanks, Joe
hey joe this is ed and i can help you with this if you are interested.
did XXXXX XXXXXd this issue over to you? Joe
Steve, The Blue/yellow stripe is the cruise control wiring which I tracked from Bentley. I am not concerned about this so I don't think this is an issue at this point. Joe
no he opted out, so i thought i would help you get it resolved.
Okay, thanks for picking up the ball. At this point, I think I have figured out that the green socket supplies current to the cruise control which is what the blue/yellow stripe wire diagram in Bentley tells me. At this point I am looking to verify which pin that wire should be plugged into and wether or not any other wires go to the green socket. Also, the TACH seems to be working erratically at this point as well. Any suggestions as to what I may have done in removing the instrument panel to create this. Maybe it is coincidental. Thanks, Joe
the blue/yellow wire goes to any of the three on the right hand side. the tach working erratically is more than likely due to the service interval or si board. it is the horizontal board in the cluster. it has some nicad batteries in there which can leak, thus producing bad solder joints. the other thing to make sure of that the coding plug is all the way seated in the cluster. let me know if i can help any further. thanks ed
