I've had a missing tab on my M62 throttle plug for years and occasionally the plug would back off and cause issues. During my recent large coolant pipe/rear manifold leak fixing adventures I broke the second tab off the plug. After some searching I was able to find a company that makes replacement harness plugs for older cars. I'm not sure what other plugs Standard makes for our harnesses, but hopefully its a wide range to help us keep our X5s on the road longer. OE engine harnesses are still available from BMW, but are over $1000.


Short of gluing the old plug to the 22 year old throttle body I robbed from my old motor, I couldn't see how to do a zip tie or other fix beyond perhaps drilling small holes in the harness-end plug and safety wiring it around the female (throttle body) plug end.
