Bosch 4-pin connector for multi-function temp switch...

[Gerard]

I picked up the connector on Friday. It was just the item, so here's an
e-mail as a reference for anyone interested:

  Multi-function temp sensor connector: 893 971 974
  Cost: a whopping $2

The catch? The plug does not come with pins. I ripped a pin off an old
loom and will get identical items from an electronics store this week.

And just to think I've been looking for this item for ages and always
got told my the dealerships that I must buy the entire wiring loom from
them. I even spent an entire $10 on a complete used wiring loom. :P :)
