i don't understand how this wire is making your knock sensor work cause the knock sensor only has one wire going to it and thats it......

[ekdave1962]

ok attached it a image of wires from tranny/shift loom,
if someone would help me identify them and there locations please

2 go to shift console and the rest go to the tranny
the yellow is labled wrong it goes to console

yeah Holden202 i disconnected them again and the knock sensor works .. im thinking that it doesnt kick in until the engine has reached a running temp ?
cos it didnt repond for a while then as engine got up to temp i started to get knock readings

thats correct there is a minimum temp setting which below this it wont work, stops false knock from things like excessive clearance on a cold motor etc.

From what I can see looking at several VN diagrams, should have the following:
Violet/White........Speed Sensor to Speedo
Black/White........Speed Sensor & Speedo Ground
Pink/Blue...........Speedo Sensor and TCC Power
Grey/Red...........TCC to ECU via pin in ALDL connector
Brown/Yellow......Speedo to ECU
Light Blue...........Overdrive switch on console (and Auto trans Temp switch so TCC can't lock up until warm)
Grey.................Park Neutral Switch
Brown/White.......ALDL Connector/Check Engine Light

Not Sure about Light Green and Yellow, Yellow could possiby be for fuel pump override from ALDL connector

thanks yoda, ill get them a try
looking at the list theres a few i wont need

Violet/White........Speed Sensor to Speedo ----not needed have converter for cable speedo
Black/White........Speed Sensor & Speedo Ground---not needed
Pink/Blue...........Speedo Sensor and TCC Power ---needed
Grey/Red...........TCC to ECU via pin in ALDL connector--needed pin 7 i think i holden202 recomended
Brown/Yellow......Speedo to ECU--think will be needed for TCC lockup so ECU now how fast we are going ?
Light Blue...........Overdrive switch on console (and Auto trans Temp switch so TCC can't lock up until warm) --- not needed no switch
Grey.................Park Neutral Switch--- need
Brown/White.......ALDL Connector/Check Engine Light-- unsure as no engine check light currently unless this is CEL ?

[ekdave1962]

hi guys,
just wanted to confirm that the TCC to ecu goes to pin A2 on the ecu is there a simple drawing that show what pin goes to where from the ecu

thanks David

You dont have a diagram? No wonder its been a struggle! Try here http://www.oldholdens.com/temp/carstuff ... s/VN%20V6/

[ekdave1962]

thanks VL i have drawing as in the manual but there not to user friendly for the average joe .. BUT these are great so it pin A7 easy with these diagrams

Thanks D
