Well, I am so close to getting this going, and last night I was fishing some wiring through the engine compartment by the alternator, and I unplugged the knock sensor connector. Well, it isn't easy getting that connector back together without tearing stuff apart again! So, I wondered, just like my supra, would there be anything wrong with re-wiring the KS from the KS itself all the way to the ECU? I would just bypass the connector entirely.

I would recommend just fixing it the right way. You should only need to remove the UIM and the Purge Control Solenoid to make the connection again. It will be tight, but it's possible.

 

actually, I don't think I need to remove the UIM. It is accessible by removing the IC pipes and the alternator...first I will try again with really LONG needle nose pliers.

 

For me, it was just easier to take the UIM off. I was unable to get enough force to snap the connector with otherwise. Then again, I didn't have all the IC piping all hooked up.

For your first few times starting the car with the replacement engine, I wouldn't worry about hooking up the cool side of the IC piping and the elbow. I would leave that stuff off so you have access to the throttle body adjustments.

 

well, just to make this easier, I am going to rewire the knock sensor from the sensor right to the ECU plug. that will eliminate the liability of the connector all-together. It worked great on my supra.

The wire is shielded between the sensor & connector.

Years ago I moved the KS to the rear housing to see if the knock readings would be the same. I had to splice the wire to reach.

Wow, the reading were quite a bit lower. So I moved the KS back to the stock location. Damn, they were lower there to now.

IN fact the sensor never registered above 10 units after that.

I find it hard to beleive it's easier to hard wire the sensor to the ECU over just plugging the thing in. To each his own I guess, but your gonna screw up your sensor.



BTW, you got a thing for leather?

 

yeah, I love leather Anyways, I never had a problem with my Knock sensors after I re-wired them on the supra..

 

The key word in your reply was "supra". Is it the exact same KS? Cut & splice away my man.
