Just bumping this thread with some info,

Bought a 2nd hand alt for my 1JZGTE JZA70R motor, found out the alt was a z30 Oval style plug./ rectangle style plug

You can purchase adaptor plugs for A70 loom to connect to Z30 alt from http://www.ashdowningram.com.au/ round australia.

Just a simple "old school denzo" to "new school denzo" adaptor for $12.
