when i am doing this swap, the D16z6 has 2 coolant temp sensors, the d15b2 only has one...

which one should i connect the sensor wire to?

 

it has one for the guages and one for the ecu. im assuming the "other" sensor you are talking about is located on the t stat housing right? if so, you can leave it alone and use the one thats under the dizzy.
hope this helps
