I've searched but couldn't find the answer. Currently I run TMCC/Legacy engines and MTH PS2/PS3 engines. I currently have ganged the ground wire from my TMCC command base throught the ground inputs on my TIU. Can I do the same with the Base 3. I'm interested in the Base 3 so I can access the legacy features on the legacy engines that I own, but I don't want to damage anything.
