mellonman Posted October 28, 2018 Share Posted October 28, 2018 I take it the injector wiring on the Jspec TT is more like the N/A wiring vs the uk spec with resistor , anyone have the jspec wiring diagram as the repair manual is for uk spec . http://www.mkivsupra.net/vbb/content.php?64-Electrical-Diagrams I would have thought that they all have a 12v feed by the looks of the diagram B+ and are earthed by the ecu. but this is at a guess and would like confirmation surprised I didn't find anything when searching as a lot of guys in the day fitted the resistors to fit uk spec injectors Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted October 28, 2018 Share Posted October 28, 2018 In the passengerfoot well, there is a grey plug that is attached to the engine harness. Pin #9 (orange/black) is the 12v feed to injectors This wire then splits into 6 wires that feed to each injector. On each injector there is also a signal (ground) wire that goes directly to ECU. Below is wiring diagram for JSPEC Quote Link to comment Share on other sites More sharing options...

mellonman Posted October 28, 2018 Author Share Posted October 28, 2018 i don't suppose you know where it splits into 6 by any chance Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted October 28, 2018 Share Posted October 28, 2018 i don't suppose you know where it splits into 6 by any chance I can't seem to recall off the top of my head. Easiest way to find out will be pulling the ecu harness through the firewall, then carefully cutting away loom tape until you can find what you are after.
