I'm planning out the additional items on my Expansion Harness, I'm looking to add an ethanol sensor, boost solenoid, manual boost map switch, and Can Lambda. Below I have a couple questions:
Can I power all those accessories off the same switched Relay? Main reason I ask is because the Can Lambda wiring diagram calls out a 10A relay for itself.
What's the best pin on the ecu to trigger the boost solenoid?
There's also two can ports on the ECU, can I use one for the CAN Lambda and the other for a Digital Dash? Or do they both need to be daisy chained off the same port?
