currently in the process of revamping my harness i built for my mkiv supra (6 cylinder) i have a few questions....
i opted to utilize the spare low side ignition, low side injector, and Peek/hold injector outputs for future expansion of fueling (secondary injectors). problem i am possibly seeing is that while doing so, it doesn't leave any outputs available to control my electronic boost solenoid (3 port). is there a work around for this? i do have a C125 display/logger with I/O unlocked. maybe use one of the 4 outputs of the C125?
second question.... i may of stumbled upon the answer in a previous thread but it is for a m400 but i am thinknig it will still hold true here.
does 5vA (pin A02) have to go to 0VA (Pin B15) and 5VB (Pin A09) have to go to 0VB (pin B16) or are the 0V pins (B15, B16) bused together internally?
