Almost finished my car rebuild, took it out for a quick run yesterday, 2 things not working - horn and engine temp.
Horn is a bodgery from the previous owner so I'll redo it, but for those who have done the e36 swap I has a question or 2:
1) Where is the brown sensor? I can see the blue one under the inlet manifold. Is it right underneath it?
2) Did this need changed, looks like a 2 pin sensor from the ETM:
e30 Coolant Temp Sender - Pin 4 C101 to Pin 26 C1
e36 - sensor B6232 - this is connected to Pin 11 and Pin 12 on the X20 connector. The wiring swap I used indicates pin 11 X20 is connected to pin 20 C101 but this doesn't seem right..
