I just finished putting a d16z6 in my 91 civic si. There is a plug on the back of the block with 2 prongs wich I assume is the coolant temp switch? I can't screw it into the z6 block, is there a place to hook it up on the z6 engine? Also none of my guages work now, tach, fuel, everything. Has anyone had a problem with this? I used a p28 ecu and dizzy with a jumper harness from rywire. Car runs good but just has these two problems.
