2G ECMLink NLTS Wire Install & Setup

The below diagram and installation procedures were pulled from ECMLink's NLTS installation article but broken down a bit more, so people like me can understand them. If you haven't seen the ECMLink NLTS procedures just follow the link ---> 2g Clutch Wire Instructions If you still have questions and want more detailed pictures follow along and this article will take you through the install from start to finish. After I finish up with the installation instructions I will also talk about setting up your NLTS feature in ECMLink V3.

*NOTE*: Use this 2g ECU pin out to refer to ALL wiring concerning the ECU harness. ---> 2g ECU pin out

Edit Note: The wire cut/splice at the ECU in steps 7 & 13-16 can be eliminated by depinning pin 91, and putting the right Amp/TE terminal onto the orange wire. Both ECU terminals, 175265-1 and 175269-1, are available from Mouser.com -- brads


Necessary Tools/Parts
  • (1) ECMLink NLTS clutch wire
  • (1) Pair of wire cutter, crimper, & stripper pliers
  • (1) 10mm wrench/socket and ratchet
  • (1) Philips head screwdriver
  • (1) Headlamp or flashlight
  • (3) 18ga. to 22ga. butt connectors (they're the red ones)
  • (1) Container of zip-ties

Wiring & Install Procedures
  1. Move the driver seat as far back as it will go and if you've got the nice leather power seats you'll want to do this before the next step.
  2. Disconnect the ground off the battery terminal so you don't accidently short something out or worse, electrocute yourself.
  3. Now strap on your headlamp and wiggle up under the dash near the clutch pedal and locate the clutch switch.

  4. After you find the switch you'll notice (2) wires going into the back of the connector thats plugged into it, one BLACK and the other BLACK/RED. Unplug the connector going into the clutch switch and put some slack on the BLK/RED wire going into the back of the plug, this is the wire you'll be cutting in a minute.
  5. Now its time to expose the ECU wiring harness so rollover and pull the driver side kick panel off the center console section.
  6. Once the kick panels off unplug all (4) ECU connections and put some slack on the 22 pin connector (B56).

  7. Locate the BLACK wire going into pin 91 of the (B56) connector, this is the wire you'll be cutting to wire up your NLTS. (SEE WIRING DIAGRAM AT THE BEGINNING OF THE POST) You'll know that you've found the correct wire if theres a BLU/YEL wire on one side of it and another BLK one on the other.

  8. Roll back over to the clutch side of the pedal assembly and grab the connector that you just disconnected from the clutch switch. CUT the BLK/RED wire approx. 1" from the back of the connector, this will give you plenty of room to work with.

  9. Expose the copper wires on both ends of the cut BLK/RED wire by stripping the insulation off with your pliers and then crimp a butt connector to each exposed end.

  10. Pull out your ECMLink NLTS cable and insert the PURPLE wire off of the cable into the butt connector crimped onto the clutch switch connectors BLK/RED wire and crimp the butt connector.

  11. Find the SHORT ORANGE wire on the NLTS cable and insert it into the butt connector thats crimped onto the Cruise Control ECU harness sides BLK/RED wire and crimp the butt connector.

  12. Now zip-tie all the loose wires together and up out of the way of your clutch pedal and plug in your clutch switch connector, your job is done on this side of the pedal assy. So once your done going zip-tie crazy roll over to the ECU harness that you pulled out earlier and find that BLACK wire going to pin 91.
  13. CUT the BLK wire going to ECU pin 91 about 1" up from the back of the ECU (B56) connector, this way you'll have plenty of wire to work with.
  14. Strip the insulation off and expose the copper wiring on ONLY the connector side of the cut wire and crimp on a butt connector (we'll deal with the harness side of the wire later).

  15. Grab the LONG ORANGE wire coming off the NLTS cable and zip-tie it up under the dash. Ensure no part of the wire sags or else there's potential you'll get your foot tangled in it while driving and who knows what will happen after that. Route the exposed end of the wire down to the cut BLK wire going into the back of the (B56) ECU connector.
  16. Once you've got the ORANGE wire ran up under the dash and have enough slack on it crimp the exposed end of it into the butt connector attached to the BLK wire.

  17. Zip-tie any loose sections of the ORANGE wire to the ECU's wiring going into the back of the B56 connector.
  18. Be sure to find the BLACK wire you just cut (on the harness side) and zip tie it up as well. The harness side of the BLK wire won't be used or connected to anything so be sure theres no exposed wires on this end.
  19. The NLTS cable install is complete so just button up the driver side kick panel that covers the ECU and reconnect the battery ground.


SETUP
Now its time to set it up in ECMLink and to do so requires you to pull out your laptop and connect to your cars ECU.
  1. Click open the RPM/TPS tab in your ECU config settings and enable your clutch cut (NLTS)
