Discussion and questions related to the course Professional Motorsport Wiring Harness Construction
I'm making good progress on my pin out diagram and laying everything out for my build. I'll be going with an AEM Infinity Series 7 ECU and was wondering if there is a rule of thumb when splicing sensory supply and sensor grounds from several sensors on which ones you should pair together or some that your really shouldn't share. Similarly on actuators. I tried sticking with anything coming in/out of the first main connector stays on that connector and anything going in/out of the second main connector stay on that connector, but there are shared items across both connectors (for example injectors are wired to both connector 1 and connector 2).
Or should you just stick with trying not to splice out more than 4 connectors to one pin?
Bump, good question that I was wondering as well!
With the infinity it doenst matter - as far as I know they are all connected internally to the same 5V/Gnd rail. With some ECU's such as Motec M1 they have the 5V and 0V pins marked in A/B/C pairs so you can get better accuracy from ratiometric sensors but that is an exception rather than the rule.
Thanks for the reply Adam!!! Glad I don't have to go back and redo things :)
