Apologies if this seems obvious questions but i can't find the answers from the wiki / manual / searching here.
Grounds - If I have a common ground outside of the speeduino, from which i ground all sensors / sheilding and also use the same ground to feed the speeduino power supply, do i need to use the ground pins on the IDC40 connector for the sensors? This would be a seperate ground to the engine block which would ground elsewhere. If i'm using the ground pins on the IDC is their any issue with more than one sensor sharing a pin?
Fuses - I can see some diagrams list some fuses (eg 10amp for coil if doing wasted spark). I can't find any diagram listing what fuse is needed to power the speeduino 12v connection. I have seen a ford zetec diagram in google images suggesting if i recall 5amp.
Finally - the IDC, i'm planning on wiring it to a couple of molex mini fit jr connectors in the case. These then connect to the outside world. To make life easier (perhaps) i've crimped a IDC male connector into the back of a molex mini fit jr pin. This means the molex connectors have male IDC connectors inside the case. I can therefore use a IDC jumper wire to wire the IDC connector on the board to the connnectors to the outside world. The only exeption is the fuel injection pins which have a special wire connecting the two ICD pins to the 1 molex pin. Can anyone see a major issue with this approach? I can provide pictures if what i'm suggesting isn't clear. Intent once everything is fixed is to hotglue the jumper wires togther to give some anti vibration security.
Intent is to wire up a 1970s ford Crossflow (kent) engine in a kit car.
