I have 3 spare wires in my engine bay and have no sensors connected. Wires are coloured

Red White - spade connector
Blue green- round push on connector
Black- round push on connector.

I think the red White is coolant temp, blue green is oil pressure warning switch and no clue on the black.

They all come out the same part of the loom on the right hand side of the bay if looking from the front, so correct side for mentioned sensors.

any ideas?

Black could be the dizzy connection maybe?

Sorry should say engines in and running so dizzy etc already connected.

Oh! No idea mate

If I did get these wrong way round, Would I damage anything?
