hi all
i am currently making a complete loom A for the monsoon ecu to run a 4g63t in a ex lancer
im having thoughts about how many relays i need to run. currently i have one for the ecu, one for the fuel pump and one for the radiator fan.
the other items i need to run a power supply to is my CAS, fuel injectors, boost solenoid and ignition igniter. can i use the main ecu relay the supply power to these also or do i have to run separate relays for all of the above ?.
also if i am correct do i use the aux outputs of the ecu to trigger the negative pins of the relays for my fan and pump ?
thanks for your imput !
