Have to admit paying $230+ for the Ram OEM IBC option, only to have to spend an additional $150 to purchase and install an aftermarket brake controller to safely brake my trailer, was frustrating to say the least.
Could have taken my truck to the dealer, but I didn't bother. For the last few years we've all been reading thread after thread (here and on other forums) about the lack of current/voltage output (i.e., unsafe braking) while using the Ram OEM IBC. All these threads and I've yet to read about anyone with a successful, conclusive corrective action (by them or the dealer) that enabled a previously deficient/defective Ram OEM IBC to work properly after the fact. Please keep in mind I'm talking about situations where a trailer in question needed 12v to brake properly and obtained the needed 12v with an aftermarket brake controller. However, the same trailer could not obtain the needed 12v to brake properly with the Ram OEM IBC.
Yes, there are those who achieve adequate braking with their Ram OEM IBC. In these cases one can only assume their trailers only require 7v-8v (or 175-200ma per a brake) to brake safely. It's common knowledge that many trailers need 12v (or 300ma for each brake) to obtain maximum braking under emergency conditions.
It is what it is.
