	The 1227808 was used on the VN and VP Auto and Manual V6,V8. As well as
the camira and some Nissan Pulsars. Uses slow speed data (160)
	The 16206305 (ECM) was used on the "Manual" VR,VS V6.V8 and is the same
size as the 808. The pinouts are also the same as the 808 and uses high
speed data (8192). This ECM is a direct replacement for the 808.  
	The 16176424 and 16195699 both PCM's (Power Control Module) 50% bigger
than 808,  used on VR and VS "Auto" V6,V8. (8192)  Both these types have
the same pin layout but their plugs are different types and can't be
substituted. Don't know why this was done but have noticed the socket on
the 16195699 has a silver coating, probably for RF sheilding. 
	There is probably other ECM,PCM with different Service numbers that
fall into the above types but thats all I have got right now.

Cheers Richard.
