hey guys, ok so like ive said before i swapped in my b16 a2 into my little sol. it runs mint, everything seems to be ok except that i have no reading on my cooland guage even when the engine is hot.. so here is the scenario for thos who havent heard it.... i used my obd 1 d series harness with the swap and converted the motor to obd 1, (i.e dizzy injectors and alternator) now i plugged in every connector from the d series harness except the evap purge solenoid on the top of the intake. there is one sensor on the back of the block, right near the knock sensor, and i have no connector on my d series harness for it. so naturally i left it, any idea what this sensor is? i thought the coolant temp sensor was the one that goes into the head under the v tech solenoid... one guy told me that there is a coolant sensor for the computer and one for the guage... not sure how true this guys statements are so i thought id ask you guys? so is there two sensors or whats the deal?
