Ok, so im trying to help out the community and build a loom for TT application next.
Here is the list I have so far. This will be for a factory replacement engine loom.

Coolant Temp (for ECU)
Knock Sensor
Injectors 1-4
Ground for the ECU
Oxygen Sensor
Coolant for gauges
Throttle Position Sensor (TPS)
Intake Air Temp (IAT)
4 transmission connections
Fan Switch
ref & sync sensors
Oil monitoring pump
2 ECU plugs & 2 chassis plugs
pre turbo control
wastegate control
turbo control (rats nest solenoid brown)
charge control (rats nest solenoid grey)
charge relief (rats nest solenoid black)

Thank you

Ryan

 

and what I assume I will not need.


purge control
fuel temp
air pump
avc
port air
-
pressure regulator (orange)
relief valve (blue)
switch valve (grey)
double throttle (green)

 

Here you go... I would keep the fuel temp and double throttle or you can offer them extra for reliability and drivability. Here you go I hope this helps...http://www.blackgto.com/RX7/wireharness.jpg
I would add the iac
The yellow emissions solenoid can be removed too.
P.S. how affordable price wise were you thinking.?

 

I would like it to be as close to stock as possible. Some of us still have to pass emissions and what not. If someone doesnt want something they can remove what they dont want.

 

A lot of people want to keep the idle speed control valve.

 

Plus 1 for as close as OEM as possible but read the title...

 

rywire , I have seen and admire your work. Curious to see how your custom made harness will turn out. I have 3rd gen customers that would be very interested in single turbo harness with bare essentials..

 

Anyone living in California will need all the emissions control circuit wires available (at least as an option).

 

We have been selling single turbo harnesses now for about a year online.

 

So we have had great success with our single turbo harnesses with basically bare bones. Issue here lies that everyone wants different things, and a fully loaded harness like oem will be very expensive, and I still have yet to locate all the plugs for that setup. The point of this post is to know what is needed for the car to run properly on twin turbo, and a aftermarket ecu. At this point im not as concerned with oem ecus, and setting everything up just like stock, as you can go to the dealer and buy a oem harness if that is what you are after. I really dont want this thread locked, so please dont ask me things about prices, and business related. Thanks.
