Okay so I found this connector and theres a wire thats completely melted on it


This Connector appears to be where the white wire connected to and where the damage appears to end... Am I correct?

 

The White wire from the Emission side of FEM-02 is supposed to run straight to the Split Air Solenoid so according to the wiring diagram the wire you recently posted a pic of is a different wire. Now if you have a multimeter then a simple continuity test will say conclusively one way or the other if it is or is not the same wire. And whether the damage ends there or not is only something you can verify. Another thing is when posting a pic of a plug/connector it would be of much help to state the wire colors in the plugs. Doing so would allow someone to be able to use the diagram to figure out what this plug and its wires purpose is.

The plug connecting to the Split Air should only have two wires, one is White and the other B/W.

 

Theres two wires shown in the picture for the split air however one is like blue or green I cant tell and the other is white/black... Neither are just white...

The 3 wires from the connector that I can still tell what they are, are Black/White Black/White and one Black/Red.

 

For clarification purposes. A plain White wire can have other markings on it but the only relevant markings are a continous stripe as all other markings such as hash marks and dots are completely irrelevant as they are not used in any of the wiring diagrams.

Secondly, has your car always been a turbo or was it swapped w/a turbo as it used to be an NA, and I say this because their wiring harnesses and colors are different.

Thirdly, in the second pic provided there are two plugs connected to each other in which you highlighted w/a red circle. How does this connector relate to the Slpit Air? Do the two wires related to the Split Air come from from one side of this connector or are you just posting a pic of another plug with some damaged wire(s)?

 

the connector in the picture(split air, 2 pin connector) is only attached to the engine harness that goes through the passenger side firewall, there is no way it is the same wire that got cooked under the brake master. the split air connector is prone to melting down though, but it usually pops the 15A engine fuse before any serious damage is caused.

the thick red/white wire in that connector i believe is either for the headlights or the A/C relay, possibly both. the problem may be in the relay junction at the front of the car.

 

Car has always been a turbo. I opened the hell out of the harness. The white wire eventually turns into a few black/white wires which goes to the IAC amongst other places. Only replaced the white wire because the rest appeared fine.

On the other side of the engine bay, I found another fried wire which turned out to be a ground wire which I believe belongs as part of a cluster with the wires that run to the switches. I've already removed this wire It now only needs to be replaced with a fresh wire.

The next step after the ground is the switches. The car is lowered so I will have to find a jack and some stands or something to get underneath it but that should be fairly easy.

To wrap it up Im going to need to rewrap all of the effected parts of the harness.

 

Didn't you provide a pic of FEM-02 which showed the Black/Blue pin fried on the front side of the harness?

 

Yes I've already replaced the wiring on the front side of the harness.

 

Then you need to make sure that wire doesn't ground out which probably damaged the wire in the first place. Either it grounded at the Split Air wire or the exposed wires under the car which you had also provided a pic of. If you reintroduce the 5th Switch that would take care of one end of the wire.

 

Im replacing everything that melted all the way through so it shouldnt melt again. before I wrap it imma have to try it.

 

The person before me mixxed the fuse box all around so it might have a stronger fuse in it than its supposed to...

 

Is it me or does the reverse/5th switch only have 2 blue wires coming out of it, not 2 green and 2 red...

I cant figure it out... did they change it out for a different switch or what?

 

Is this a JDM transmission? If so, then it would not have the 5th gear switch.

 

Im not sure. Are the usdm and jdm switches interchangeable?

 

I don't truly know but I don't think they are interchangeable. And are you asking if you could place a 5th gear switch plus reverse switch in place of the current switch?

 

yes thats what I was asking. if theyre interchangeable I could just grab a usdm switch... otherwise I might as well grab a whole new trans because my second gear grinds anyways...

 

They are interchangeable. I have a USDM switch in a JDM S5 TII transmission.

 

Okay good Ill just grab a switch than... Will help this whole wiring situations...
