Take a look at a supra wiring diagram first(I got a factory service manual from e-bay). All the important stuff is the same as the Aristo. The acc. may be different. If you get a motor from a JDM Aristo and factory wiring harness from aristo there is one plug that is different than the supra. Good luck finding pinout for this plug.You need to power the ignitor/coil through this plug. I started mine on a stand using no relays just switches with fuses. I suggest by-passing the clutch start cancel by using mometary switch direct to starting solenoid or through relay to solenoid and not through the ECU. Fuel system has seperate ECU. When ignitors are powered power the fuel pumps at the same time no need for this ecu. Its not really too hard to figure out. All the info is out there already.

Try reversing the polarity to electrode negitive. This is for low penetration welds. Most welding mach. can be switched in minutes just reverse the electrical leads in front of the spool. Most solid core mig is electrode positive for deeper penetration.

I have a l28et motor I removed from my car. It was in running condition with no problems at the time. I live in the S.F. Bay Area. I have no use for it as I'm installing a 2jz GTE and 6 speed into my 240. Let me know if you are interested.
