If this was a "proper" harness, then you should include the NC (normally closed) relay as shown in the standard, to "open" the bus as required. You could do that with an 8-core cable, 4-wires to bring the signal in and 4-wires to take the signal out back out to the IBBC. The 4 wires that you'd need to bring into the cabin (and loop back out again, into the back of the implement socket). The Deutsch DT connector, would be disconnected and the "harness" pictured below inserted between it and the IBBC. The round plug going to IBBC can be left alone. See marked up wiring diagram below, showing how you could wire up a harness to/from the IBBC back to a 9-pin in-cab socket. Have you looked how the ISOBUS loom enters the back of the ISO implement socket (officially called the IBBC)? There should be two connectors, one round plug (CAB177 on the parts diagram) for the power connections and one square plug a Deutsch DT connector (CAB180) going into the back of it (tractor side). True you could, but doing it either way you'd still need to careful you don't exceed the maximum "stub" length of 1 metre and you don't accidentally 'open' the bus if you've got nothing plugged in to the cab socket. There are other similar kits that I have seen described out there, that tap into the ISOBUS where there is no 9-pin cab socket. This together with a 9-pin CPC kit like I linked to in post 27 would then allow you to connect up your control box (It might even be worth giving Muller a call to discuss). There should be, and I think I can see it on the parts diagrams ("CAB113-1" and "CAB113-2" ?), but you really need to check with them. If there is a place on the existing ISOBUS loom on your tractor that has what is known as "BUS extension connector" (4-pin Deutsch DT plugs). You'd then need to make up an adapter cable to hook up to your control box.Ģ. What is the pinout/ does it have any access to ISOBUS on any of the connector pins. The circular roof connector, that links back to your Data3 terminal. The only alternatives that I can suggest is that you speak to the tech's at your dealer and find out:ġ. You're a bit between a rock and a hard place. Yeah I think I understand what you're getting at, but I don't think you will find it will be that simple, certainly if you are thinking of hardwiring into the rear ISOBUS implement socket on the tractor (its actually more than just a simple socket). Unless its listed somewhere in your tractor manual or the dealer would probably tell/be able to find out from the service manuals. Unfortunately I've got no way of telling what the pinout of either L22 or L111 would be. This is connected back to the Datatronic, but it also has two other branch connecters on the loom a 2-row rectangular connector and a 3-pin inline connecter which connect up the circular socket "L22" in the roof. It should be located somewhere around the Datatronic screen/armrest (I found reference to it on a very vague diagram I found, see below). Without a proper wiring/CANBUS diagram its quite difficult to tell, but it looks like the circular connector, labelled "L111" on the Datatronic loom is a diagnostic connector connected to the tractors CAN bus. I could be wrong, but I don't think your tractor came with what we now know as a "standard" in-cab ISOBUS 9-pin CPC connector, even though it came as optioned for ISOBUS, and has the rear implement socket. Don't think it makes too much odds whether its Perkins or Sisu, the looms look pretty much the same either way.
