...Hmmm
Getting ready to get back at it now. I was hoping to wire the fuel pump up like in the PM I sent....using the info below that I got from Collin awhile back.
Gonna go try to figure out how I'm gettin B+ to he pump now, but may be where I put all of those black/red wires together like below...
___________________________________________________________________
The ignitor power wire is the big fat (black/orange?) wire on plug B2 right next to the starter wire (black/white). There is a pin on the Aristo that has two black/orange wires going to one pin. These are the ignitor power supply wires leading out to the ignitor. I twisted those two together and soldered them to the big fat wire coming from plug B2.
The circuit opening relay was a little more tricky. starting at the plug next to the fusebox, the larger black/red wire supplies power to the ECU and the circuit opening relay. Again, with the wires B+ and B1+ from the ECU I twisted them together and soldered them to a 16g wire coming from the fusebox plug. Where the body plugs split from the harness (I extended my ECU 2ft futher), you must splice into this wire and run it to the larger red/black wire on plug B2. This is the positive for the circuit opening relay.
I hope this helps a little. One thing I haven't figured out is a good way to control the fuel pump. It's switched by the circuit opening relay which is controlled by switching the ground for the little green wire on pin B2. The 7M ECU turns this on and off as it sees fit, but the 2JZ ECU does not seem to have the same switched ground point for the pump, so I grounded it permanantly. What this does is make it so the fuel pump is running any time that the EFI main relay is turned on. AKA any time the ECU is plugged in and the key is turned to on. It works, and my engine runs like a champ, but I wish there was a better way to control the plump.
