Morning Frank, like I said anything that I can see has a Toyota patch saying WHAT it is. Nothing says Toyota Alarm, immobiliser, TVSS or anything at all. I can only see a couple of boxes in any case. Some heater bits, emission control and such. There are a heck of a lot of loose plugs in there and some do look un Toyota like. There is a light blue female bullet connector for eg. When did Mr T use bullet connectors?
Yes the siren module is still on the inner wing where the ABS would sit. That is branded Toyota. There is a bonnet plunger above the wiper motor area that has been disconnected. It has a small eye on the end and looks as though it was originally connected to the plunger. It rather feels as though a PO has had problems and just pulled the lot out.
