Full retrofit loom to wire in heated seats and electric rear sunblind on your e39. Covers connections to both seats, switch pack, fuse connections and ibus wire. Not normally included in the original BMW retrofit kit but a handy addition for a later date is the wiring for an electric blind it's easier to add it in at this stage and leave unplugged till required. If your car came with a rear window electric sunblind please message as the harness will be simplified for what you need.
This will also give a reduction in price. Virtually all wire colours are the same as OEM BMW wiring, those that aren't will be noted on the supplied diagrams as part of the kit. Made from genuine BMW/AMP parts (no Chinese poor quality terminals).
All properly crimped, no pliers and soldering here! All looms are made to order and carry a maximum 3 week lead time. Most likely can be done within a week it just depends how long parts take from BMW. This highly impacts the overall price. Based in the midlands UK.
