280Zone Posted February 25, 2007 Share Posted February 25, 2007 It looks like a signal or hazzard flasher plug type. Quote Link to comment Share on other sites More sharing options...

alexideways Posted February 25, 2007 Share Posted February 25, 2007 Just trowing something up here, but could it be for an Auto. transmission? Quote Link to comment Share on other sites More sharing options...
vashonz Posted February 25, 2007 Share Posted February 25, 2007 Fuel pump relay if its on the 240z harness. On the zxt harness I have no clue, if it had yellow wires going to it I would say it goes to the transistor. Quote Link to comment Share on other sites More sharing options...
Mr.INSANE Posted February 25, 2007 Share Posted February 25, 2007 It looks like a signal or hazzard flasher plug type. It definetly is not the same type the flashers plugs are an L Shape Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted February 25, 2007 Author Share Posted February 25, 2007 it was from an Auto hmmmm should i do something with it? or will it mater if i dont cause i havent done anything with it yet hmmm Quote Link to comment Share on other sites More sharing options...
eec564 Posted February 25, 2007 Share Posted February 25, 2007 Well, I'm not 100% sure, but I think I know what it is. That plug is right next to the ECU connectors, right? I have the same thing on my 82 N/A, and it connects to pins inside the ECU. Those pins are the exact same thing as the little green LED that blinks in time with the O2 sensor. I figured that out on my car by taking the ECU appart. The FSM I have lists that connector as "Not Used" for both N/A and Turbo. Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted February 25, 2007 Author Share Posted February 25, 2007 unused is exactly what it has been so i guess that clears up that hmmm thanks guys Quote Link to comment Share on other sites More sharing options...
GrayZee Posted February 25, 2007 Share Posted February 25, 2007 Yes, un-used... don't even give it second thought. Quote Link to comment Share on other sites More sharing options...
twoeightythreez Posted February 26, 2007 Share Posted February 26, 2007 I believe that goes to an altitude switch, but that was only installed on cars that were expected to be at ....high altitude areas. My 280z had one. The factory ECU would enrichen it's map slightly if that switch (if equipped) closed. Dunno if it's the same on a ZXT but that's sure what it looks like.
