single turbo wiring help
single turbo wiring help
i really need some help on the Identification of some of the cables im not 100% for my chopped down engine harness. this is going in my RX4 BPT. i have plenty of pictures and wire colours to help.
first off is this the fuel temp plug?
(ss= silver stripe)
Green plug;
wire colours are black brown ss
green white ss
Do i need it and where will i plug it in with me using this in my RX4?
PICTURE

AIT ( air inlet temp?)
black plug, yellow inside;
Green ss
black brown ss

Obviously i need this, have i to replace the plug along with getting a new fast reacting IAT sensor, and where is the best place to put the new sensor? as near too the throttle body as possible?
IAC, What is this and what does it do?
white plug;
blue green ss
black white ( i assume this is a ground?)

thermostat water temp, i have 2 plugs
Green plug;
black brown ss
brown yellow ss
Black plug;
Blue yellow
black white (Ground?)

the green one fits onto the socket on the water pump housing rear ide but where does the black one go?
water thermo switch.
does this wire, red black go with this black plug? does this plug tell the ecu the temp. and then this turns the fans on? do i need it or can use something aftermarket to control the fast through a seperate thermoswitch and manual switch?

what does this black plug do?
blue ss wire
black white wire

i think this is the AWS, however i dont know what it does and what it stands for.
black wire with braiding

TPS
2 X brown white ss cables ( i think they were crimped together, i assume that this colour wire is voltage/power as it is splice throughout the harness for various things)
black green ss
green red ss
black brown ss

what does each of these wires do? i assume one is power/voltage, a ground and a return signal to the ecu to tell it what the TPS is doing.
the plug for the TPS on my EFI hardware throttle body has 3 cables in it,
Red- voltage in?
Green- return signal to ECU
Black- Ground??

what is this black plug for?;
yellow white ss

GEarbox plugs;

what does the yellow inside black plug 4 pin do?
red ss
yellow ss
blue ss
white ss
Grey plug 2 pin, orange inside
brown ss
green ss
what does it do?
Brown plug, orange inside 2 pin;
orange ss
green ss
Black plug yellow inside 2 pin
green yellow ss
yellow red ss
