The black temp sender will need to be replaced by the brown one from the M20 (1 pin).

the 'black' one needs to stay.
its sends information to the ecu.
you can screw the m20 brown sensor into the water manifold next to the black one. theres an 'allen' bolt there that you can remove and replace with the m20 sensor. then take the brown/purple wire from the black plug and put it to the m20 sensor
