Hi guys, i'm in the process of rewiring my jap imported S4 infini. Running into a few spots i'm getting stuck at due to the microtech being wired in and where the previous owner butchered the wiring. Any assistance would be greatly appreciated. I have used the current flow diagrams, but they are shitty for finding connections due to how they address the system rather than the loom.



This one is just to give you an idea how it sits in the car.

1 goes to the connector near the fuse box under driver's dash(RHD), 2 are a/c unit connectors, 3 is the blower motor harness and that side of things connector, 4 is weird button, 5 is the cigar lighter light. I've layed it out how it would be if you were facing the dash.

This one is just to give you an idea how it sits in the car.





1. Not sure what both these connectors do. The first picture is under the driver's seat and there are two of them. The second picture is in the wiring harness along the driver's side scuff panel.





2. In these two pictures, there is a black/green wire & black wires going into the T-plug, red/green & black wires which are snipped as they were for the alarm, also a black/green & black/yellow wires into a two pin connector flat housing. What are all those for and is that node point standard?



3. There is button type switch that was fitted in the glovebox, it has red/green & black wires running to it which were soldered into aftermarket wiring running up to the button as you can see.



4. Is this clump of wires for the original radio?



5. This t-plug with yellow & black wires. What is it?



6. These blue/yellow & blue/red wires, what are they for?



7. Where can i get this microtech plug from? I've tried Jaycar and another place and they couldn't help. Waiting for a response back from Microtech.

 

The wires either have a stripe or they don't. Describing the wire colors properly would help a bunch. When the wire has a colored ring on it that is irrelevant as the wires are decribed by the main color and the appearance of a stripe or not. So describe exactly what plug, number of wires and their associated colors are.

 

this looks to be for the glove box thing (not sure the technical name). if you open the glove box, the plunger turns the light on inside the box.


one of the plugs under the driver seat is likely for the exhaust over heat sensor

 

Ahh sweet, yeah it did have a factory fitting, was just strange how they rewired it.
