help really confused on how to do this! temp sensors and shti!
 

Ok I got a b18a1 block out of my 91 integra this block blows ass so I got a b20 block.
The sensors are nothing alike and the b20 block doesnt have a breather. I got a aftermarket breather and I think the hoses hook up to the allen wrench ports on the back. So I wont be able to use the green sensor in that port on the b18a.
I also won't be able to use the sensor with the 2 prongs right above oil pressure sender because there is no hole on the b20 block.
I will be using the stock obdo harness. the b20 block has some kind of temp sensor on the thermo housing but im not sure which sensor this replaces.


here is the b20 http://i96.photobucket.com/albums/l1...llinab/b20.jpg


and here is the b18a1 with the 2 sensors that r ------- me up http://i96.photobucket.com/albums/l1...inab/b18a1.jpg



also I do take out both those allen ports and thats what my breather plugs into right??

thanks for the help i figrue this best place to ask! i searched tons of places for efs/obd0 and cant find anything

First thing on this site you are gonna hear is post porn then search, but ill help cause im board ;D. The one on the left of the oil filter is obviously your oil pressure sensor, the one furthest up is the coolant fan switch found on obd-0 blocks.The new block has it on the thermostat housing. And the on all the way on the left is a oil temp fan switch only on the blocks of obd-0 integras,i think, we did not use it on 2001 ls motor that we put in my buddies 91 teg. That should be every thing, good luck.

You should just be able to rewire the fan switch from you engine harness to the thermostat housing fan switch, it will be a different connector though. So scour your local the junk yards.
