DarkBlack Posted April 26 Report Share Posted April 26 Hey Guys, im Swapping my 620 J15 with A CA18DE (JDM S13 Sivlia Q´s) and need your Help with understand the Wiring to the ECU. I Got every Wiring Diagram i need. ECU Pinouts are matching the DET version to 99%. Basic Questions: - Do i Have to Splice the Wires to the ECU in the existing wiring (From Relays , Chassis and Fuses i will be Putting in Front of ECU), or can/should i cut the ECU Cables and connect the needed Wires ? As far is i think i know, are these all "Input" signals, such as, ECCS Power , Ingition Power and Fuel Pump. - i got 2 White Connector-Plugs within the Engine Harness (with 1x 18 pins 1x12 Pins). Can´t i just connect the needed cables there? the ECU has no other Connection to the Rest of the old Car, so the Wires that im Splicing/Connecting, should also connect to there? Im a bit confused as you see, maybe some of you could help me get my thoughts about this straight. Thanks ! Quote Link to comment

Icehouse Posted April 26 Report Share Posted April 26 The wires you need to tap into are the wires that went to the S chassis engine bay plug. Don't cut anything at the ECU. The diagram mike link to is one I made years ago. Your motor wiring is the same as the turbo version. I had the NA CA18 in a 510 20 years ago. What a great engine. 1 Quote Link to comment

DarkBlack Posted April 28 Author Report Share Posted April 28 Okay Guys, time for a German saying : " even a blind Chicken finds corn sometimes " .i Just was stuck at the wrong connectors / plugs on the Harness 😂 Found them, now it makes all Sense😅 For reference, the Plug that connects to the Power ist a Gray, rounded one at the end of the Engine Harness 1 Quote Link to comment
