Download Repair Wiring Harnesses for BMW E34 Touring – BMW E34 Touring Rear Wire Harness Repair Layout – The repair wiring harnesses for E34 touring models are universal for ALL applications (Europe, Japan, US, etc). The part numbers, as noted in other resources like ETK/websites are: 61 10 8 365 702 Right main harness 61 10 8 365 704 Left main harness 61 12 8 355 153 Rear window defroster 63 25 8 359 099 High mount stop light The high mount stop light wires (two wires in one sheath), and window defroster wires (two wires in one sheath), connect directly to plug ends behind the grommets where the harnesses enter the D pillar. If you observe how things are assembled as you are taking the old wiring out, you will see how they should go back together. At the other end of the respective wiring, the high mount stop light has two spade ends that connect to the back of the stop light, while the defroster wiring needs to be spliced in to the leads coming off the grid on the rear window. Cut the existing ones 4 or 5 inches from where they are attached to the window and solder and shrink wrap the new ends to them.
