Piggy-back for OBD plug

Postby risham » Sat May 03, 2014 7:25 pm

I was wondering if anybody might know where I could purchase a piggy-back plug for my OBD plug. My brake controller is controlled and hooked into the OBD plug and I believe I am going to need it for an exhaust brake also. I could use a splitter(Y) or a piggy-back or something similar

I guess the question is why is your brake controller plugged into your obd port? Do you have a max brake or direclink controller? The Jacob exhaust brake I had on my dodge did not hook into the obd port either. On my 04.5 you had to put in a vacuum pump to run the brake. Now this was many years ago and I'm sure products have changed.

My Banks exhaust brake on my 06 Dodge used the OBD port there was a piggyback arrangement on it. You exhaust brake vender should have the info for you.
