Yea I'm throwing a knock sensors code and I poped my hood and noticed I didn't have one. When I do get my sensor I was wondering how to install and what I need to do. There's 2 connectors that fit and ones a little longer reach the knock sensor. Which one do I plug into the knock sensor?

 

depends on your motor and ECU. what are they? the knock sensor threads into the back on the block. usually 1 wire is grounded to the thermostat housing and the other wire goes to pin A17 (B-series)

 

gsr motor gsr ecu obd1

 

I outline the two plugs that are free. Which is for the knock sensor?

 

It a single wire sensor underneath the intake manifold.

 

o ok which in the picture is it? I see that I circled the temp and o2 I think.

 

Mine was a single Blue wire but i have an H series..

 

Ok once I thread the knock sensor into the block wheres the plug that I'm supose to connect it with?

 

So you bought a new knock sensor or something and havent installed it. If so just match up the connectors. Are you using the gsr engine harness?

 

Yea the things is the 2 connectors that I outlined in red are free and aren't connected to anything. I was confused because I didn't know what connecter to put into the knock sensor. Come to find out the connectors that I outline in red are really the o2 and temp sensor and actually what I outlined in yellow is the knock sensor sonnector.
Please correct me if i'm wrong

 

if you have an obd1 ecu...have it chiped and disable the knock sensor...way less headache
