If you just ground them together trough the uln they have a tendenscie to start ossicilate at the slightest voltage drop, like cranking and when the ignition is switched of.

I quite like the idea of using a spare output just because it involves less messing around with wiring but I have no idea how to set it up. I've found the programmable output window in Tunerstudio but I need to find out which numbers the output pins are.Ground the 'extra' relays and use the switched +12V from the fuel pump relay to power them. 3, 4, 5, however many relays can be powered this way from one Speeduino fuel pump output.
I'll do some research and see if I can bodge something together next weekend.
Thanks for your help!
The advantage over the inginition switch - if the switch is left on, Speeduino will cut off the relays.
