Homer Posted March 30, 2008 Share Posted March 30, 2008 Here's a challenge for you all, can you help identify what each of the plugs in the pics below are for? 1. Connects to steering box, not sure what it does 2. Oil level sensor (I think, it attaches to the block) 3. Alternator 4. EGCV VSV or Wastegate VSV 5. EGCV VSV or Wastegate VSV 6. Narrowband O2 sensor 7. Water temp sensor for ECU 8. Water temp sensor for temp gauge 9. Coil pack connector 10. Coil pack connector 11. Coil pack connector 12. Coil pack connector 13. Coil pack connector 14. Coil pack connector 15. IACV VSV 16. EGBV VSV 17. Injector #1 18. Sub Trac TPS 19. TPS 20. Trac stepper motor 21. EVAP VSV 22. Knock sensor 23. 24. Noise filter 25. Igniter pack 26. 27. Fuse box 28. Fuse box 29. injector #2 30. injector #3 31. Either MAP, IAT, or Cam position sensor 32. Either MAP, IAT, or Cam position sensor 33. injector #4 34. injector #5 35. ICV stepper motor 36. injector #6 37. Cam position sensor 38. Either MAP, IAT, or Cam position sensor 39. Vehicle speed sensor 40. Knock sensor 41. Probably autobox 42. possibly starter motor 43. possibly starter motor 44. The first pic shows the ones at the far end of the loom (go around the front of the engine). http://img153.imageshack.us/img153/7411/image006ct5.th.jpg And with more detail: http://img215.imageshack.us/img215/1707/image003up6.th.jpg http://img153.imageshack.us/img153/7117/image002hm8.th.jpg http://img215.imageshack.us/img215/6613/image005fd7.th.jpg The next set go over the top of the engine (obviously most are coil pack connectors): http://img503.imageshack.us/img503/6232/21image006iu0.th.jpg These are around the throttle bodle area (presumably TPS, etc) http://img153.imageshack.us/img153/2929/image009ok5.th.jpg I'm not sure where these are from exactly, but they are just down the loom from the throttle body ones above): http://img215.imageshack.us/img215/852/image013rn4.th.jpg These ones go to the ignitor, and something else? http://img215.imageshack.us/img215/1818/image014za3.th.jpg These I think go somewhere along the intake manifold (presuably injector related?): Two of the plugs are cut off (31 and 32) http://img215.imageshack.us/img215/4008/image015mg7.th.jpg The final set go around the back of the engine I think: http://img527.imageshack.us/img527/6884/image016hh6.th.jpg Quote Link to comment Share on other sites More sharing options...

RobSheffield Posted March 30, 2008 Share Posted March 30, 2008 Thats as many as i can do without going out and looking. Quite a few will be VSV related (one is on the vac tank under the runners) and other bits you certainly dont need. Quote Link to comment Share on other sites More sharing options...
Ian C Posted March 31, 2008 Share Posted March 31, 2008 This is off the top of my head sat at work so I may be wrong on some (I've corrected Rob's clanger on the injectors though #1 is on a different part of the loom) 1.

Homer Posted March 31, 2008 Author Share Posted March 31, 2008 Brilliant work Ian, thanks very much mate!! Lol at the last few, got a bit carried away with the numbers First post is updated, any ideas on the missing ones? The ones in Red need verifying. There doesn't seem to be a Crank position sensor listed, I think that might be 1. or 2. Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted March 31, 2008 Share Posted March 31, 2008 I've corrected Rob's clanger on the injectors though #1 is on a different part of the loom Pfft, i was just starting it off for you but yeah, you are right, number one is elsewhere Quote Link to comment Share on other sites More sharing options...
Homer Posted March 31, 2008 Author Share Posted March 31, 2008 Pfft, i was just starting it off for you but yeah, you are right, number one is elsewhere Oops, sorry mate, I thought I'd already replied to you - doh! So, a belated "thanks very much" Rob Either 1 2 or 3 has to the the CPS plug, Ian said 3 is the alternator which makes sense so I guess it must be 1 or 2.

Ian C Posted April 1, 2008 Share Posted April 1, 2008 Oh I think 2 is the crank position sensor, that means 23 is probably the oil level sensor -Ian Quote Link to comment Share on other sites More sharing options...

georigg Posted April 1, 2008 Share Posted April 1, 2008 Homer, Go to, http://www.internetwork.org.uk/supra.html where you can download a complete set of manuals including all the electrical sections which cover plug locations, plug types, wiring harnesses etc etc. You can then look at your leasure and follow each harness route on yourcar.

Rgds George its http://www.internetwork.org.uk/manu/system/system.htm (my site ) I woundnt download it as you'll be there for ever unless you want to and Then I'll do a zip'd version for you Quote Link to comment Share on other sites More sharing options...
georigg Posted April 1, 2008 Share Posted April 1, 2008 Hi heckler, A big thanks should go to you for the content of your site. Having been there before, I knew that Homer would find all the info he needed on harness runs, plugs and locations of same. Best regards, George Quote Link to comment Share on other sites More sharing options...
