JaredJ Posted August 18, 2019 Report Share Posted August 18, 2019 Hi there, new to these ecu’s. I’ve mounted up my iat sensor just wondering if there is existing wiring I can use for it ? Same with external map sensor is this able to be wired off the old Maf wiring ? Or best to get an xl loom ? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 18, 2019 Report Share Posted August 18, 2019 Assuming you have a plug-in ECU, is it a GTS/GTR plug-in or the R34 GTT plug-in? Quote Link to comment Share on other sites More sharing options...
JaredJ Posted August 18, 2019 Author Report Share Posted August 18, 2019 That might help ! Gts/gtr plug in Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 18, 2019 Report Share Posted August 18, 2019 The easiest option for the IAT sensor is an exp loom. Otherwise you can run your own two wires back to the ecu and connect it to pin 36 (AN Temp 2) and Pin 50 (sensor gnd). For a MAP, that ECU has one onboard so that is probably the easiest. If you really want to you can connect an external one to the MAF input but there is no 5V power supply at the MAF connector so you would have to get that from the TPS or ECU connector.
