And yes im running direct switched power to the pump, when the switch is on, the pump is on. but i did wire it through a toggle switch so that i can cut it off if i need to check other things with the switch on. I also have a relay for the fuel pump and 10ga wire running directly from the battery to the pump..
I started researching my wiring last night and ran into the M-REL pin question for my 2JZ wiring. I was necromancing this thread and I see I'm not the only one who got stuck on the M-REL pin lol! Two videos on YouTube say to connect 12v to that pin yet the WILBO diagram pinouts say that pin is an OUTPUT and provides signal to actuate the main EFI relay to power the O2 sensors, fuel pump, etc. Why would I put power to a pin that is an OITPUT and already has power? It seems like that is asking for trouble or possibly letting the magic smoke out of the ECU.
I think I am going to leave that pin disconnected and see what happens. (First I'm going to check it with a DVOM to see if it is has any voltage present and if it's enough to actuate a 30A/40A relay) I will likely run separate relays and fuses to the fuel pump, O2 heaters, etc so that I can cut the main relay out of the equation.
Working on restoring a black 1988 Conquest automatic with 139k miles, tan interior, and in need of TLC. It will be my "driver".
