for the watertemp this is what i did

i went to honda and ordered a new housing with a hole for some sensor, and i took a fitting in there, and then i took the sensor with the gauge and put it in that fitting. looked OEM. then ran the wire

for the air/fuel i THINK its A-10 on the ECU, you might wanna check H-T out tho

good luck man, lude is really coming along/
