ecu pin out charts. do they exist?

[TheoM]

So the presence of an external immo as reflected by the wiring diagram will confirm the absence of the internal Immo in the ECU ? Guess we need that correct wiring diagram then.

Once again, huge thanks for your replies and help. I am in way over my head with this

no I was talking about some early [edit: VVTI] crowns do not have immo at all

I once heard of 1997 ls400's being very specific with external immo unit (I even happen to have virgin 93c66 dump for the unit)

However afaik the rest 1uz vvti's are all with internal immo requiring only amplifier and antenna.

Thanks Goerge. We are hopefull that this one doesn't have internal immo and if all goes well startup might happen this week.It will be in a auto Hilux sfa.If all goes as planned we will then unplug the signal from the box to test the reaction of ECU as we plan to go that route on my BJ 42 LX wth H55F manual box, so hold some thumbs !
