The following pictures show how to configure the TechWorks ECS Controller Jumper settings for the following

o Use Large LEDs or Small LEDs

o Use Rotary Switch or Push Button Factory Switch

 The following picture below shows which fuse is associated with which strut

Option A Larger LEDs: These are 4 individual LEDs strung together. Each LED requires either 0.473" or a mounting hole these are fairly large as an LED goes.

Option A Larger LED Outer LED Housing Diameter is 0.473" ( 12mm)

Option A Larger LEDs: The LED Diameter itself is 0.308" ( 7.8mm) - You can drill a hole this size and just have the LED itself poking thru

Option B Smaller LEDs: This is a single LED assembly that has 4 smaller LEDs mounted into an small round installable assembly that only requires a single 11mm hole to expose the LEDs

Option B Smaller LEDs: The Diagonal distance across the LEDs is 0.474" ( 11mm) - You can drill a hole this size and just have the 4 LEDs poking thru

 Epoxy the LEDS to the back of the tray

 Cover the top surface with smoked plexiglass  or plastic.

The fiber optic cable used in this example  was  qty 4 - three foot lengths of  Toslink fiber optic audio patch cords.  You can order them from  www.monoprice.com for like $3 apiece.  In this example I'm abusing my very expensive Monster Toslink cable - which is no better than what you can get from monorprice.

If you need extra mounting depth  OR you want to have the 4 ends of the fiber cable very tightly grouped together- you can strip away the plastic end connectors.  

In this example - I drilled four small holes into the cruise switch  tray.  I did not strip away the ends in this  mounting example. The depth of the plastic shield  relative to the tip was just right for mounting to the back side of the tray below.

This would NOT be a good place to mount the fiber optic ends of the cable because of the directionality of the cable.  It has a very narrow field of view.   A better place for the fiber cable would be directly in the console or the bezel immediately around the console so that the cable ends face the driver.     The console tray still shows how small the fiber holes are though.

The other end of the cables are untouched. 

The back side showing how the fiber cable was epoxied to the back of the console tray and also my quick hack duct tape tubes to temporarily provide a way slide the LED status lights into a stable position so they butt up against the end of the fiber optic cable.  Something more permanent is needed here.

(1)FRONT SUSPENSION:  The  same Front suspension mounting H/W dimensions are used for  1991-1994 3000gt VR4 AWD ECS equipped Cars  AND  the later model 1995->1999 VR4 AWD  NON ECS (Electric Sunroof) models.   This statement is refering to the physical sizes and geometry of the suspension hardware only.  meaning things like the spring sizes (not rates), strut cartridge physical mounting dimensions (pearch size etc) , these are the same size & mounting geometry & Hardware.  

(2) REAR SUSPENSION:  The strut cartridge & mounting H/W dimensions for the 1991-1994 model year 3000gt VR4 AWD ECS equipped Cars  IS DIFFERENT compared to the later model 1995->1999 VR4 AWD  NON ECS (Electric Sunroof) models.  Specifically the strut cartridge spring pearch is smaller an so therefore is  the spring. 

However - on the car supspension frame mounting points i.e the dimensions and geometry where the complete strut cartridge assembly mount to are the same.  This means you can swap out the non-ECS strut assembly and replace it with a rear AWD ECS strut assembly.   This is also true for the rear struts in the late model  3000gt SL versions that did not have ECS.  You can swap out the strut cartridge assembly and replace it with an early model rear ECS SL strut assembly.

So specifically What OEM Hardware is required for doing a  retrofit of the Mistubishi OEM ECS strut & spring assemblies  into a later model year care where no factory  ECS was supplied?

The intent of the retrofit is to add back in some form of ECS control into the car - using either an aftermarket  or a custom controller or retrofitting the complete original full factory ECS system (have fun with that).

This scenario applies to  1995 ->1999 3000gt VR4 AWD or Dodge Stealth variants.  These later model cars had instead from the factory different fixed rate springs & non-controllable fixed rate struts.  With the factory ECS option removed that also meant the removal of  all  ECS specific sensors, ecs wiring harness feeds, ecs connector, ecs computer etc

ANSWER:

For the Front struts you technically  only need to  replace and order the following:

(1)Strut Hex Cap nut (40089c) , 

(2) the Spring (40176)  (the OEM ECS spring is different from the OEM Non-ECS spring - the rates are different)  , 

(3) the strut cap electrical connector (40081)

and (4) the strut ECS cartridge itself (40041). 

For All the other mounting hardware for the front should be the same.  However you might still want to replace any of the rubber mounting pieces due to wear .

For the Rear struts you need to replace everything - all the mounting Hardware, the strut cartridge and the springs. 

NOTE:    if you  are doing the complete retrofit you obviously  have the option to use aftermarket springs (like Tein H-Techs or S-Techs) instead of the factory OEM ECS springs.  This is what I did for my retrofit.  Tein H-Techs gave my 1998 VR4 about 1" of drop and reasonably firm ride but not overly so.

 ECS System Retrofit

The Tech Works controller can also be used in 1996, 1997, 1998 or 1999 Mitsubishi 3000gt or Stealth cars that do not have the Mitsubishi Factory OEM ECS system.  It allows you to be able to retrofit the electronically controllable struts back into these later model year 3000gt cars or earlier model year cars that did not come with the ecs option.  

To do the ECS Retrofit into   3000gt or Stealth you:

·         Remove your  non-ecs struts and replace them with  Mitsubishi 1995 model year standard factory OEM ECS struts & mounting hardware.  You can use the OEM Springs or use after market springs such as Teins.

·         Install  the Techworks Controller and connect it to your vehicle +12v & Ground

·         Run a 4 wire cable from the controller to each of the 4 struts

·         Run  6 wires  from the controller  to your console area for connecting the LED display, Tour/Sport Lights and  the Push button ECS Switch .

Retrofit Overview

When doing a retrofit using the Techworks ECS controller you have the following  options for doing the retrofit 

        o  Status Display Lights and Controls:

o    Push button Control Switch:  you can retrofit in and use  an OEM Factory ECS pushbutton switch (that you provide)  or you can use an aftermarket simple Pushbutton switch that you mount in any location you choose.

 o The pushbutton switch needed is a single pole normally open / momentary closed type.

 o   If you want to retrofit in the OEM pushbutton switch there are instructions in this manual on which pins to use

o    Sport /Tour Status Lights or TechWorks LEDs – you can do just one or both of these options

 o Sport / Tour lights:  you can the existing factory Tour/Sport light mounting location in the console and wire up OEM lights or you can use a simple small single color LED & resistor in the factory location instead. You can also mount these two lights in a custom location of your choice

·         The Sport / Tour Lights are connected to the controller using 3 wires  - two power wires & a common ground wire

·         For LED choices search on Amazon for “LED with Resistor”

o   Techworks 4 LED Multi-color Display  - This a Techworks option and these LEDS are special multi-color programmable/controllable LEDs.  For these you would custom mount in a location of your choosing.  There is a small version & a large version of these leds. 

·         The Techworks 4 LEDs are connected to the controller using 3 wires  - a Data signal wire , +5v wire , Ground wire.

         o  Connecting Everything: Wiring runs and wiring harness

o    Since your doing a retrofit – it means that your car doesn’t have the OEM wiring runs and wiring harness plugs to plug into the controller. 

o    You will have to install & connect the wiring runs for the switches, lights,  LEDs and struts as needed.

o    The Techworks controller has two different sets of wiring ports that are supported.  You can use either of these to accomplish the retrofit

o 24 PIN Techworks Molex Retrofit Connector Adapter Harness

o  The Techworks Controller has a 24 pin Molex port that has everything you need to support all the combinations possible.

o   You can order the adapter harness from Techworks or you can use  an 24 PIN ATX Motherboard Power supply cable to plug into this port.  If you order this from Techworks is will come with all the leads labeled.

o   If want to use the Techworks LEDs  OR if you want to hack the controller software and use the I2C communications buss then you must use this connector

o Using Factory OEM F12 / F13 Connector Ports

o  If want to do a “pure” oem retrofit then you can cut the F12/F13 connector ends off the factory wiring harness for a car that originally came with ECS.  The F12/F13 Connectors plug into the Factory ECS controller and the Techworks unit directly supports these connectors for the plug n play OEM replacement option

o  A limitation of using just the F12/F13 connectors is that you will only be able to retrofit using the sport /tour lights.  You will not be able to wire up the LEDs  nor will you have access to I2C buss if you want to hack the controller.
