R4CER Posted January 16 Report Share Posted January 16 Hey community! First time post, long time reader whilst learning/researching my standalone ecu journey. I just wanted to check to confirm that my understanding of how I should wire my ethanol sensor/IAT sensor is correct. I've attached some images based on the pinouts I see. But at a high level here is my plan. Ethanol content sensor (link style). 1. 14v switched feed taken from the fusebox (I only have one extension cable so no 14v feed available that I can see if I use extension port 1?). 2. Grounded on the chassis in the engine bay. 3. DI wired to DI11 below, red cable on pinout in image. Intake air temp sensor (link) Senor wired temp4 on expansion port 1 below (grey wire) and grounded on the gnd pin (orange wire) also expansion port1 (believe that polarity isnt a consideration here?). Thanks in advance for all the help and guidance. -Alex Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 16 Report Share Posted January 16 Your pic hasnt worked, but yes that all sounds ok. Another option for the IAT is to wire to the MAF plug which is already in the engine bay with AN Temp 2 and a ground in it. R4CER 1 Quote Link to comment Share on other sites More sharing options...
