GWR not needed on dodge in data mode?

Question

i was looking up the manual for the evo-all with t-harness and noticed there is no GWR connection listed, is this accurate? I ask because it appears to be needed on all other platforms i've used and if so why is it needed on other firmwares (hyundai and ford for example)?

Answer 1

Technically you do not need it in any installation using datalink. I would still connect it as habit even though a guide would indicate not required in datatlink. The only vehicles I wouldn't bother connecting it is in the Nissan / Infiniti with a Tharness.

so its not needed on any vehicle while in datalink mode? for example if i was to use it on a hyundai which lists it as being a required connection?

GWR is normally offered through datalink.

so even though the guide says its a required connection (bold line) its not needed in datalink mode?

Next car you do. Don't connect the GWR. If it gives you problems, connect the GWR.
