RB25DET/MS3X Swappers - Please Step In

Post by Scottie-GNZ »

Folks,

electricals is not one of my strengths, so bear with me. I am converting an RB25DET (in a 240Z) to MS3X and have a couple of questions:

1. Wiring the CAS - I am following the DIY writeup and need a clearer understand of the following: "You will also need to connect 1K ohm, 1/4 watt resistors from TPS VREF (pin 26) to both the low resolution signal and the high resolution signal to provide a pull-up in the wiring harness." Could someone kindly draw a simple diagram of how this would be wired.

2. AAC wiring. The OEM harness that was in the car is a disaster. I have tried tracing the 4 wires on the brown and purple connectors back to the ECM and can only come up with the red/brown wire on the brown connector going to pin4. Could someone please post up where the other 3 wires need to be connected. I have a brown connector with a red/brown wire and a blue/white wire and a purple connector with a yellow wire and black wire.

Thanks.
