Original units glow system + one other, the silver and black boxes I can see in your photo are screwed up under the dash above glove box. I would send a photo but I’m back to the firewall of my HJ75 Ute. There are also some mounted behind the passenger kick plate and some others to the left of the drivers legs. From memory Black box with long metal bracket up goes to the right with silver glow timer box on the left.
