1 Written by john200 PDF by STiMPY Thanks to Phatty & BenTaylor200 for the S14a ECU pinouts Thanks to Bren for the S14a ABS ECU wiring This guide is specific to the S14, the S14a has different wiring. See the final two pages for S1a specific wiring. WARNING... YOU NEED A LAPTOP to configure the TC Disconnect the battery. The contents of the box (check it's all there)

2 Take off the sill tread plate and the passenger footwell trim to reveal the ECU, unclip the wiring cover.

3 Lots of wires, the injector pulse wires are at the bottom. The tacho wire is the Blue & Black one just below the center. The 12v power is near the top Injector 1 - White & Black Injector 2 - Yellow & Black Injector 3 - Green & Black Injector 4 - Blue & Black 7 - Revs / Tacho - Blue & Black 59-12v (ignition switched) - Black & White

4 Shows where to attach the TC earth wire

5 Remove the plastic cover from around the bottom of the ECU wires, and cut the wires one by one attaching the plug connectors (make sure you put all male connectors on one side and all female connectors on the other). Crimped and solder these, just to be sure they won't come out. Put the tacho and power wire into the supplied plug, but you need to loop round wires on the TC wiring harness...

6 Once the ECU wires are into their plugs (take time to make sure they match both each other and the TC harness), connect them together and make sure the engine still starts. (remember to reconnect the battery and turn off the immobiliser)

7 If the engine starts then great.!! Disconnect the battery again and plug the TC harness in. (the yellow and pink wires are the loops mentioned earlier)

8 Now run the ABS wires back along the sills.

9 Take out the rear seats and parcel shelf. Then carefully pull off the rear interior side trim. Run the ABS wires along the same route as the rest of the wiring loom.

10 The ABS unit is in the boot on the left.

11 17 - Front Left - Blue The top plug is the one you want, there is a release tab on the back of the plug, also remove the wires from the plastic bracket (brown thing on the left) by cutting the tape, this gives you much more room to work with. The pins are: 15 - Rear Wheels - Blue 13 - Front Right - White 17 - Front Left - Blue

12 Connect pin 15 to Green and Yellow on the TC Connect pin 13 to Blue on the TC Connect pin 17 to Red on the TC Connect the shielding to something, or make sure it's covered up.

13 Make the wires neat again. Now position the TC ECU (on the angled bit under the carpet for instance) and connect the wiring harness and laptop connection / diagnosic LED. Run the wire to where you will mount the adjustment box and connect their wires. Put everything else back together and reconnect the battery, turn the ignition on. Plug a laptop in to the serial connector, run the TC software. Select your com port Read data from the TC ( 3rd icon from the left under the menu) Make the following changes in the wheels section: -Select the front wheels as reference -Select the rear wheels as driven (edit) -Set FR to CH1 -Set FL to CH2 -Set RL to CH3 -Set RR to CH4 (end edit) -Set your tyre sizes (click on the wheel icons) -Set the driven 'Pulses per revolution' to 74 -Set the reference 'Pulses per revolution' to 40 Make the following changes to the Configuration section: -Set the number of cylinders to 4 Write the settings to the TC (4th icon from the left under the menu)

14 Save the settings into a file.(2nd icon from the left under the menu) Start the engine. In the test section click send, this should make the engine missfire for a brief period. In the Real Time section, click 'start real time' (5th icon from the left under the menu) and go for a drive. if there are numbers in all the boxes and they change as you are driving... Well done, you now have TC in your car.
