[DRAG.ONParticipant broken hillve vk hdt retro blown cammed vf 25th clubsport build number 42 of 100 vnss tuff 355 was blown now going turbo View build HERE Member since: October 2, 2017 Posts: 25]

used this wiring conversion on a vk and hq

i hope i havent missed any

You will need 2 relays (4 pin) , one is a fuel pump relay and the other is a efi relay. On a relay there are 4 pins which have numbers next to the pins, the numbers are: 85(switch power), 86(negative earth), 87(power supply direct from battery), 30(wire to item that will receive power)

 

>black plug on the efi loom in engine bay (near battery)

Red wire:

Positive(+) power supply for injectors when ignition is switched on. Need to connect this red wire to relay pin 30 (this will be the efi relay) via a 30amp fuse (before connection to pin 30 on relay). Connect pin 85 on relay from a ignition on power supply ( a wire that will give positive power when ignition is switched on only) , connect pin 86 on relay to earth, and connect pin 87 on relay to direct battery positive (+) power.’So relay should click on and off when ignition is turned on and off.

violet ; purple wire;

Positive(+) power supply for fuel pump (via oil pressure switch) when ignition is switched on. Need to connect this violet wire to relay pin 30 (this will be the fuel pump relay) via a 30amp fuse (before connection to pin 30 on relay)you will need to connect a wire from your fuel pump (+) with this violet wire to relay pin 30 (so two wires go on the same pin on relay) as this will give power to the oil pressure switch and fuel pump when the ignition is switched on(the computer is designed to only run the fuel pumps when there is oil pressure  a precaution and thats why the violet wire runs through the oil pressure switch) Connect pin 85 on relay from green with white trace wire on the black pulg( this wire that will give positive power when ignition is switched on only via the computer for one second and then cuts out until you start the engine and there is oil pressure)  connect pin 86 on relay to earth, and connect pin 87 on relay to orange wire on black plug ( this wire goes to oil pressure switch as a direct power from battery) and also you need to join a wire direct from the battery (+) to this pin(87) on relay as well. (so two wires go on the same pin on relay). So relay should click on and off when ignition is turned on and off via the computer.

Orange wire:

Positive (+) wire to oil pressure switch direct from battery to fuel pump relay pin 87 ( read above in violet wire)

red with black trace wire

Positive (+) power supply for computer. Connect this red with black trace wire direct to the positive (+) battery power (continues power) via a 30amp fuse. No relay required. This will give continues power to the  Fuel pump switch wire from ecu to fuel pump relay pin 85 (read above in violet wire). Will give power to fuel pump relay to switch on and off ,

Green with white trace:

Fuel pump switch wire from ecu to fuel pump relay pin 85 (read above in violet wire). Will give power to fuel pump relay to switch on and off

Grey plug on efi loom in engine bay (near battery next to black plug)

blue with white

Ac cooling fan relay(gives negative (-) power) (not required to hook up this wire anywhere) or you can hook up you themos to this wire via relay (and it will switch thermos on when water gets to 91c) can be altered by tuner

light green with black trace wire:

A/c relay (not required to hook up this wire anywhere) unless you are running air con

blue wire;

Oil pressure light, give positive(+) power to a oil pressure light in cabin. Does not need to be hook up if you dont have a oil pressure light, or you can just put a small led light on you dash and hook it up to that. (optional) specially if you run a oil pressure gauge.

Green (next to blue wire)

Coolant temperature signal wire, this give you a reading on you water temp guage. Best to put a aftermarket electric water temp gauge with new sensor, as the vl dash gauge will give you a wrong reading with the original sensor on the motor.Connect this wire to you receiving signal on you temperature gauge.

Green with black trace:

not needed

Brown wire:

A/c switch. (not required to hook up anywhere) unless you are going to connect the air cond up.

>Brown with red trace wire:

Tacho signal, hook this wire up to your rpm tacho gauge.

Black plug on efi loom in engine bay the 1 with 2 wires;

purple wire;

Starter motor solinied positive (+) power supply. This wire need to be hook up to igntion starter, so when you turn the key to start it give power to the starter motor to turn over.

Brown wire:

Alternator dash light positive (+) output, this wire needs to be connected to a battery light on the dash, otherwise ti will no charge the battery if it is not hook up to a battery light.

white plug near computer inside car

Brown with white trace wire:

Check engine light negative (-) power output. (must connect) connect this wire to a light somewhere on you dash to negative wire on the light and the positive wire from the light should be connected to ignition on power

Brown with yellow trace wire:

To trip computer. (not required to hook this wire up anywhere)

Pink plug on efi loom near computer (inside car):

This plug hooks up to your transmission wiring loom if you are running the turbo transmission. If you are running a trimatic or manual here are the wires to be connected:

yellow with white trace;

Trip computer. (not required to hook up any where)

grey wire:

Inhibitor switch, negative (-) power input. This wire needs to be connected to you inhibitor switch on your gear stick so the computer knows when it is in park on neutral. if the car is manual than this needs to be earthed out to negative (-)

Grey with red trace wire:

torque converter clutch solinied. (not required to hook up any where if not running a four speed transmission)

pink (next to grey with red trace wire)

Anti theft circuit. Need to connect this wire to positive (+) ignition on, otherwise it will no run the computer, this wire can be hooked up to your immobiliser relay so the car will not start unless this wire gets a positive power supply

(you will need to find the + ignition on the 1 that stays on when you hit the starter there is 2 + ignition  ons with the old holden 1 goes dead when you hit the starter you need the 1 that stays live

light blue wire

Auto transmission temperature switch/ 4th gear. (not required to hook up any where if not running a four speed transmission).

now she should fire up
