SR20DET TPS / CAS Wiring

Recommended Posts

 

Just wanted to confirm my details are correct here, in particular is the CAS earthed to the ECU or to the engine block? 

And if someone can confirm I have the correct pin locations for the ECU plug for each of the signals as illustrated in brackets (x)

Thanks in advance.

Yes, that looks fine.  TPS doesnt need to be shielded.  

For the CAS ground you can use either engine or sensor ground.  The ground pin on the Nissan CAS's are actually coupled to the metal body so get connected to engine ground anyhow.  But if I were making a custom loom I would ground it to the main engine ground rather than sensor ground so then sensor ground isnt coupled to engine ground.
