If you mean just the connectors, google search for automotive connectors (I did this recently looking for the dash plug for the 899). There's a heap of suppliers, and many of the plugs are 'standard'. Eg that two-pin plug looks very common, and the other ?six? pin plug also looks very familiar.

Come to think of it, I've probably got both here. I've got several donor looms that are contributing plugs to projects. I'd be surprised if I didn't have ones that fit. Got a pic of the inside/pin layout?
