Hi, I have looked for this topic with no luck and this is my first Speeduino I have a v0.4 board and would like to run the fuel pump, fan, etc from the ecu.
I have the board all wired up to the car and started testing. i have found i have no 12v output for the relays. have i missed something or do i have a bigger problem

P.S.
also having problems with oil pressure witch i believe is i need a 1k resister as its reading way to high.
No trigger signal from a dizzy witch i plan on fitting a trigger wheel

The ECU switches the ground connection to the relay, I suggest that you spend some time studying the wiring diagrams in the Speeduino Wiki.
You need to provide more information about your issue with not having a trigger signal from the dizzy, does it have any trigger wheel fitted at present? is it points, VR or HE?

Thank you low side switch relays, I did not see that. As i said I'm very new to speeduino i will look again for a fuel pump rely wiring diagram on wiki.
