to SevenMKIII: I don't know about connectors, but I'm sure that all 7M-GTE igniters are 3-channel multiplexed, so they are compatible.
I don't see any reason why Toyota should change connectors pinout too... Moreover, my pre-88 igniter has green connectors and its pinout is the same as in Cygnus's TSRM (that is for after-88, iirc).
