Sorry it confuse me as both use same words so not sure which is which! Thought better ask you. Thank you Christopher Lanfranchi Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 16, 2019 Report Share Posted June 16, 2019 Pin A4 goes to one of the pins on the spill valve. The other pins goes to ign switched +12V. From the GDI specific wiring info in the help file: Quote Link to comment Share on other sites More sharing options...
