Hi. I was called out to a towtug today. On the plate it states SIMAI T5 800R or could be 900R. Never heard of this make till today. It has a zapi ac-4 controller with 2 line contacts. The first line contact comes in but the 2nd one doesn't. Customer replaced both with 2 new contacts.
I was hoping to plug into the zapi unit but this one has a saab connector and no plug in options to the zapi unit. Was hoping someone might have a wiring diagram they could share so I could try fault find.

Would be great if someone has heard of this vehicle and has some info on it.

Regards
