i got a question..im putting together my ls-vtec motor and im setting everything up to run my catch can and on the back of the block i have 3 plugs...one is the oil pressure sensor then it has another sensor which minei believe is broke i just see 2 pins sticking out and then theres another sensor that has a green plug..

what sensor is this? is it safe to unscrew that off and use the honda plug for a catch can?

im running obd1 del sol

 

heres a pic i found online that shows exactly which 2 plugs im talking about and is there a way to identify if i have a 90-93 block or 94-95?

 

anyone??

 

i believe that is your knock sensor

 

i think its the fan switch

 

I thought knock sensors were on the OBD2?

Isnt the fan switch located on the tstat housing?

 

knock sensor

 

i was doing some searching but not too sure but i believe the green plug on the back of the motor came in the 92-93 ls and instead of the switch being on the thermostat its located on the back of the block?

i guess i just have to cut my hardness plug and extend the wires to the back of the block

can anyone confirm?

 

LS doesn't have knock sensor

fan switch on b18a's, b18bs have it on the thermostat housing

 

my thermostat housing doesn't have any fan switch thats why im confused, could it be i have to just extend wires to the back and use that plug for the fan switch?

 

heres another pic i found of my green plug

 

bumpp

 

The fan switch IS on the back of the block on the LS and its NOT on the t stat housing. The fan switch is beside the green plug you have you extend the wirels for your fan switch if your using a 92-05 harness. As for the green plug i never used it so there for not caring what it was for.
