AlexLSX7 Posted May 8, 2018 Report Share Posted May 8, 2018 i have 3 dual SPA Design gauges in my car and was wondering if anyone had used the 5v Signal from them and wired them into the Link? I would like to have the Fuel Pressure wired into the Link for safety purposes and logging. If you look at page 7 you will see the plnout for the plug http://www.spa-uk.co.uk/SPA/docs/DG60 manual issue 1.1.pdf Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 9, 2018 Report Share Posted May 9, 2018 It should work but it looks like the sensor ground may be tied to chassis ground in the gauge so I would only connect the signal wire to the ecu only (dont splice the ground to the ecu).
