question about 1g Engine harness

[Stainbox12]

I just bought from ebay, a 91-94 NT harness. I have a 90 awd turbo. and i have some questions.

Does this NT 91-94 harness has the connector for the injector resistor?
The CAS, Coil, and Igniter from the 91-94 NT harness have plugs 90 style plugs or 91-94 turbo plugs?. Because i heard somewhere that NT harnesses use 90 style kind of plugs, is this true?
In the event that the harness is really different, i would need to buy CAS, Coil, Igniter, TPS, and ISC right?

The reason im doing this is because, my 90 turbo harness is melted everywhere and its really ripped of everywhere.

the turbo's have different wiring for the MAS sensor as well as the knock sensor too, also the 90 coil is 3 wire and the 91 to 94 is 4. I'd say just get a 90 harness... but it's up to you

You Are better off getting a '91+ Turbo engine harness.. thats what i did I also have '90 turbo...

1.The NT don't have the resistor BOX, but it's easy to modify the harness! Look under the tech articles here, you will find that you only have to go with 1 wire to the ECU..and the other 4 connect to the inj..look it up.
2.The 90 Ignitor Coil has a 4 wire connector. The 91+ have the 3 prong so you would have to get 91+ style ignitor+coil pack; OR you can modify the harness to make it work..do a quick search you will find them on this forum;
3. Detonator sensor has 1 wire that needs to go into the ecu; the 91-94NT don't have it so you will have to run that to the ecu;

4. The FPR solenoid has 1 wire that needs to go to the ECU also; the NT don't have it in the harness -so you have to run that to the ecu also;
5.WGA solenoid has an orange wire that has to go into the ECU; The NT harness doesn't have that...so you need to run it to the ecu;
6. the idle switch and airflow sensor are reversed in the 91+ harness, so you have to swap that around+ the NT cars have a diff. air flow sensor;
If you are okay with soldering then you can make the 91-94NT harness work in your 90.

You don't need to run any wires to the ECU for the resistor pack. All you do is take one line for power from the original injector to the pack and then run the 4 other wires off the resistor pack to the injectors.

Don't forget the 7th wire for the MAF that needs to be run to the ECU

thx for correcting me. I was thinking of the power wire, but I spelled it wire to ECU for the resistor box;
