what sensor is pluged in right by the thermostate, the water temp???, also what color wires are supposed to be pluged into that sensor?, a b16 btw

 

fan switch is on the thermostat housing

 

what color should the wires going into the harness be, and how many wires is it, i lost it in my wiring somewhere. or hooked it up to the wrong sensor

 

bump

 

in obd-0 it should be 2 wires. 1 one is black and the other is yellow/green. The black goes to a ground and the yellow/green to the radiator fan relay.

 

it should not matter that i converted to obd-1 should it?

 

i can not find the plug for the life of me, what is it next to when it comes out of the main harness???, can someone take a picture for me please, i really wan to get my swap running, but if my fans dont turn on that could be a problem . any help is appreciated.

 

no, it shouldnt matter. on obdo motor the fan switch is on the back of the block on obd1 car the fan switch is on thermostat housing, it has nothing to do with the ecu it just turns the fan on thats it

 

ok that makes sense now to me thank you but i still have an issue as the plug is not the same, i can chage it but i need to know which wire needs to go on top and which needs to go on the bottom, i already extended the wires, so the only thing left is figuring out which wire goes where. anybody know?

 

bump

 

anybody?

 

help please

 

order doesnt matter. switch just completes the circuit. either way will work

 

thanks so much, it was really bothering me that no one seemed to know, could the fact that i did not have this sensor pluged in befor be the reason why everytime i turn on my car the temp sensor would max out?

 

Like Crx Jimmy said, the order doesnt matter

And as for your last question, the answer is yes. If the fan doesnt turn on, there is no way that the coolant in the radiator will cool down and your engine will just get hotter and hotter. After you connect the sensor, let the temperature go to the middle and wait a few more minutes until the fan turns on, just keep an eye out on the temperature gauge so it doesnt overheat.

 

Had th same problem we swapped a B18b into my rex I'm still OBD0 and my friend said I didn't need it well my fan never turned on and after a few runs at the track and let my car idle for a little it over headed and puked coolant...

the OBD0 sensor is on the back of the block had a rubber cover over it was 2 wire I though it was like brown and green/yellow but I may be wrong I had to extend the wires to reach the thermo housing, the sensor has the same plug as like 2 or 3 other so i just got one at the JY and r wired it...now my fan turns on but I also found a hole in my rad so i just orders a new JK cross member and a alum rad and slim fan

I can get you some pics if you need HTH

sure how much did it all run you

 

well I got a bunch of stuff, Alum 1/2 rad, 12"slim fan JK crossmember, and then B series head flange, T3 flange, and 5 bolt echaust flange to make a mani and DP all ran a little over $500 but well worth it, I am excited because I have Konis and GC coils and putting the ES bushings in soon too the car is gonna handle amazing, hoping to put some nice 60' times if i get traction

where did you get the rad fan and crossmember from

 

I got them from LSD Motorsports on HMT I think they are on here too or check out lsdmotorsports.com &lt;---I thnk thats in google it if not

 

what about the radiator and fan

 

I got everything from them, e-mail or call them I don't think its on there site but they do carry them

 

i agree my only question with this is i tested the obd0 sensor from the back of the block i got no ohms just like .08 volts tested the sensor from a b20b in the thermostate housing and got no volts but read 3. ohms my question is for now is are they the same type refrenceing sensor i understand the way the fan relay system works just didnt know if they worked diffrentlt to acomplish the outcome------------
