vn V6 wiring diagram

[Buick3.8]

380 -400km's per 90Litres of Premium is not good

I need a PDF of the engine wiring loom.. If i can't get it i'll put a TRUSTY FORD WINDSOR in it..

Read thread carefully... I HAVE CHANGED EVERYTHINHG OTHER THAN THE LOOM!!!!!!!

IT IS A MARKS CONVERSION AND THEY AREN'T THAT FLASH ON THE WIRING SIDE OF THINGS
AND THEIR SHOP WON'T HELP ME WITH THE PROBLEM...
SO THEY CAN SUCK A BIG BAG OF DICKS
I went and bought a Gregories Book but it has shit all and shows the fuel running in the opposite direction of flow.. hahaha
I have a hilux 4x4 with the vn commo v6 conversion.
I purchased the car with conversion done and love it to bits but the only problem is that
it runs so farking rich!! I have replaced every component other than the loom and wonder
if i have a bad wire conection or a break somewhere. Any way the wiring needs a tidy up
and i'm going to to replace the loom with one from my old vn while i'm at it.

Please throw all your idea's at me about the poor donk running rich

And can i get a link to the wiring diagram

Thanks a million.

Main factors in rich mixture:

1) fouled oxygen sensor
2) fouled coolant temperature sender

Have they been replaced?

yeah mate have changed all old for new including the bosch fuel pump and the stock
regulator. i have a fuel preasure gauge installed to make sure it's set correct..
i've changed the ecu and put stock chip in.

all sensors are new from holden and got new injectors ect..
maybe the temp sender isn't wired in to ECU???

life isn't meant to be easy and cars are my life!!! hahaha
cheers for your help

I wonder if you have a manifold leak or something along that line so the computer thinks the air mix is to high and pumps in more fuel? Dont know if it's possible. But if all the main sensors are changed with new and the connectors are OK... vac leak maybe??

When changing the O2 sensor on my 88 wagon the connector failed and the car just ran rich. I hooked up the laptop to the car and the O2 sensor was not reading any volts. I replaced the connector with the good old utilux items nd away it went.
