So I'm not using a relay board in my 6 conversion. I have cut the 14 point harness where it branches to the trunk, so maybe just 2 ft off the end. I left the starter wire the full length. In hindsight I should have left the tach and idiot light wires just as long, but it's OK, enough to butt splice. Anyway, there are 2 red wires(switched 12 volts) I was planning on 1 for the ECU and have the other kick on the fuel pump. Is there any reason I need to run a relay for the fuel pump?

For my Microsquirt the fuel pump works exactly like DJet - it runs for a second or so when you turn the key, and will shut off if the ignition turns off.
My system has a small fuse panel that gets power from the plug off the relay board at the very bottom left, from port IV in the diagram Clay posted (I think thats the one - its one of those 4.) Zach |
