I am installing a Jacobs exhust brake that I ordered from Dodge as well as a Brakesmart brake controller in my new 04. 5 6speed dually. My question is has anybody installed the same and how did you route the cables through the firewall. It seems there is only one access hole and it was put there for a possible exhust brake applicaiton. I do not think there will be enough room to route both through the same hole. Any thoughts?
