Dan Bloomfield Posted March 1, 2021 Report Share Posted March 1, 2021 If I have a switch between the relay and aux output as pictured, mainly used to immobilise fuel pump & coils/injectors using a factory unused dash switch with duel input/output will I need to enable a pull up resistor due to lowside switching, if available on aux channel. Or will I need to use a digital channel insteed.. Xtreme+ Quote Link to comment Share on other sites More sharing options...
Vaughan Posted March 1, 2021 Report Share Posted March 1, 2021 Wouldn't it be simpler to wire the switch into the ECU as a DI and then set it as antitheft or Stop Switch? This way the ECU wouldn't inject any fuel or trigger any spark when the switch is set to its disable position. Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 1, 2021 Report Share Posted March 1, 2021 And your switch will work fine as drawn. Quote Link to comment Share on other sites More sharing options...
