Help Parking Brake indicator wire route.

Hello
Can someone help with the route of the BR/BU wire from the parking brake switch to the instrument cluster
Thank You

The ETM shows the wire goes to the white, horizontally mounted multi-connector on the back of the cluster pin 23. It does not show any connectors on that trip so it really doesn't matter how it gets there but to use less wire it might have gone up along the tunnel up the left side of the cluster to where it joins other wires going to that connector and it got wrapped at that point.

www.e38.org/e28 has the ETM for the cars, middle of the left column.

Thanks Blue Shadow I ended lifting up the carpet on my car 87 535is (DC74) the wire goes to the rear seat in the center of the tunnel and goes back up to the front on the driver side. Most likely the wire is cut where it enters the rear seat. I found another sheathed wired going to the trunk and a few loose wires under the rear seat do not think they are original might be tied to the suspension the car also has a high end CB radio antenna. I suspect they are installation remnants from PO.
The problem with the ETM the routing is not always clear when there is no splice involved.
