Mystery wires with 16v kr weber conversion

Hi everyone,

Already found the very extensive topic on engine wiring, but still have a couple of questions about some remaining wires.

I'm in the process of converting to a 1.8 16v Kr engine but I'm having issues with a couple of wires i'm not to sure about where they are supposed to go, or if I need them at all..

I've got the CE1 fusebox and I'm going dual webers.
Descriptions is what I figured from the electrical topic.

These should be good:
Yellow/red - coolant temp sensor
Yellow - High oil pressure (need to lengthen it but thats ok)
Black/blue - low oil pressure

These are a mystery:
Black/purple - Thermal switch for inlet manifold heater?
Black yellow - Overrun cut-off valve?
Black yellow - Was already taped up, Low coolant level switch unit?
Black with two connectors, no idea what these were supposed to do. Think some kind of coolant sensor thing based on pictures of old engine.

All seem to have been connected to the side coolant flange on the old engine.
Do I still need these? If so, where do they go on the 16v?

Thank you in advance!


Mystery wires:


From old engine:
Black wire with 2 connectors seem attached to coolant flange
Black/purple wire seems connected here too.
Black/yellow with red connector on the bottom too
Do I need these on the KR? Where should they go?
