Guest |216| Posted April 10, 2012 Report Share Posted April 10, 2012 30 - battery 87 - fuel pump 85 - 12v switched (must be swicthed) 86 - aux 1. Quote Link to comment Share on other sites More sharing options...
Guest |851| Posted April 10, 2012 Report Share Posted April 10, 2012 I think it is better to setup the vipec to drive the signal to ground, only aux 5 and 8 can be used to drive the signal up, with limited current, so better to use gnd driving. pin | signal 85 | battery via fuse 86 | Vipec 87 | pump 30 | battery via a fuse here is my setup for the second fuel pump, connected to aux 2 this is the extract from the manual Quote Link to comment Share on other sites More sharing options...
