Editing VLT ECU into R31 (section)

=How To Do It=

To get around this you will need to purchase a relay and wire as described below.
I used a 5 pin Narva relay, which you can buy from any auto outlet / Kmart.


#Remove kick panel in passenger footwell.
#Unscrew ECU from Body.
#Remove R31 ECU, by removing the 3 connectors.
#Before plugging in the VLT ECU, cut the pure white wire on the 15 pin connector...from the ECU. This is pin #108
#Join this wire from the loom side (Not ECU side) to pin 87 on the Relay.
#Now on the 20 pin connector look for the "White with Black stripe wire", what you need to do with this one is splice into it rather than cut. This is ECU pin #16
#Now join a wire into the white and black wire and connect it to Pin 86 on the relay.
#Run a wire from pin 30 on the relay, and earth it, I earthed mine to the ECU mounting bracket.
#Connect a wire from a 12v ignition power source to pin 85 (I think I used a wire under the passenger seat for the Auto comp which I no longer required, but any will do)
#Plug VLT ECU in, once the ignition is turned on, the pump should run for 5 seconds then switch off. If so everything is fine.



The relay should be wired like this:

*Pin 30 Earthed
*Pin 87 White wire (joined to loom side)
*Pin 86 White with black stripe (spliced into)
*Pin 85 12v Ign power
