My parts computer says:
MA70= 70A
SC300 = 100A
GS300 = 90A
JZA80 = 90A 6 spd, 100A A/T
Not sure on the 1JZGTE.
All I know is that with the pulley I put on it, mine (JDM 2JZ) puts out 109 Amps on out test bench, which will be more than ample, and paired with new cables, and a Optima...
This harness allows:
Use 1JZ Alternator with round plug on JDM, USDM (?) 2JZ, etc engines with oval alternator plug.
Use higher amp Aristo 2JZ alternator on OE 1JZ harness.
Wire JDM 2JZ alternator to USDM round plug mA70 alternator harness
Etc, Etc.....
Without soldering...
One has the pcv oil vapor-into-intake in the middle of the "T" connecting both compressor inlets to the intake tube
The other kind, the oil-in runs into the number 2 "T" to compressor air tube
The two wires are an in-out for the reverse lights switch.
Search for a post where a guy was wiring a R154 into a 4runner for the diagrams, etc that I posted
I have a 2JZ electric pump on a 1.5JZ.
Haven't run it, but I imagine more power, cleaner look, and ability to test for leaks while the engine is off by powering it up for a day :)
