I am putting a B18b from a 95 integra into a 91 and useing the B18b manifold, everything is fine but the B18a block has a sensor that goes into the water jacket by the oil pressure switch on back of the block and the B18b dosen't (what is this, a sensor for the dash guage???)and the B18b has a sensor in the goose neck but the B18a dosen't, does this do the same thing, can i just lengthen the wires and change plugs on the B18a harness. And yes i am useing the the B18a harness.

the sensor in the goose neck ( t stat housing ) is your fan switch. the switch that is on the back of the a1 is the fan switch, so you need to get a connector for the b1 fan switch and wire it to the plug that used to reside on the a1.
