*WARNING*
The following information is based on a 2003 350z wiring diagram, checked against JWT's 350z wiring diagram and the ECU pinout available on multiple sites


Z33 Gas pedal plug E123 pinout goes like this

Plug Pin Color ECU Pin Color(if color changed) What its labled
Pin 1 Green/Red ----------- Pin 83---------------- GndA2
Pin 2 Red/Yellow ---------- Pin 98 (Green/Blk) --- ApS2
Pin 3 Black/White --------- Pin 82 --------------- GndA
Pin 4 Black/Orange ------- Pin 91--------------- AVC C2
Pin 5 Yellow --------------- Pin 106 (Grn/Orng) -- Aps1
Pin 6 Blue ------------------ Pin 90 (LghtGrn)----- AVC C

Z33 OBDII Plug goes as follows

1 emtpy
2 empty
3 empty
4 Black (Ground) Behind instrument cluster Plug M30
5 Black/White (Ground) Right side of dash Plug F152 (Turns black at plug)
6 Blue (CAN Line H)
7 Purple (K line)
8 Green/Yellow 10amp Hot IN or ON Start
9 Empty
10 Empty
11 Empty
12 Empty
13 Empty
14 Empty
15 Red (CAN Line-L)
16 Red/White 15amp Hot At All Times

*THESE LINES CONNECT TO OTHER DEVICES AS WELL BUT THIS IS JUST THE SIMPLIFIED WIRING INFORMATION DOUBLE CHECK TO SEE IF THE NON-LISTED DEVICES ARE USED WITH YOUR SETUP BEFORE ELIMINATING THEM FROM THE HARNESS*

* Pin 6 Blue Can line H goes to ECU Pin 94
* Pin 7 Purple K goes to ECU pin 85 but turns Light Green somewhere in the harness
* Pin 15 Red Can Line L goes to ECU pin 86


At this point all that is left is a the dash plug pinouts, and power and ground pinout

to get a tachometer signal you are going to need a greddy 6 cyl signal adapter, otherwise you will blow out coils
OR you can use a gauge cluster that is designed for CAN
