You need to move the wire that currently goes to pin 6 on the module so that it now goes to pin 5. (on each module if you are changing both..)
In the Q4 there is no actual pin in the header in the pin 5 position so you need to either move the wire in the header or (more simply) just insert a new pin.
This module is the typical one that people who use Motec or Autronic would use but it will work fine with the standard ECU as well if the above mod is made..
cheers, jim..
