Hi there. I am bulding my harness for my Mazda Miata 99 model,with an adapter so i am using my exhisitng engine harness in order to terminate it to my Vipec i88,with plugs A and B. I have the ECU pinout but i have some leftovers pins from my ECU that i cannot decide where they should go on the Vipec. 1)First my ISC valve has to wires which are 3M and 3Q pins on my ECU.According to Vipec manual ''Two terminal ISC solenoids need only one auxiliary output (or ignition channel) to open the solenoid. A spring is used to automatically close the solenoid. Connect one terminal to the engine managements power supply and connect the remaining terminal to an Auxiliary/ Ignition Output Output. The orientation of the wires does not matter. An ISC solenoid must be wired to a switched power supply.'' So if i am correct one of them should go to one Aux input and the other to +14V in Vipec plug A.My ''problem'' is that +14V is used in order to feed the Vipec.Are there any other pins in Vipec's plugs that give +12V output?Can i use the Aux +14V 9/10 on the plug B? The leftovers for completing the harness are the following. 2)1A Back up power supply(What is that really?) 3)1H Battery positive voltage monitor 4)1O General field coil control 5)1Q Generator warning light 6)1T Generator 7)3K Fuel tank level Note that the original alternator was controlled by my ECU.I purchased an old type alternator with the regulator build in from an older Mazda Miata. Attached is the ECU pin out. Thanks in advance,any help appreciated. 1999_ECU_diagram.pdf
