While at the Good Sam Rally in Datona I attempted to have my allison transmission diagnosed by a technision, and he was unable to locate the hookup in my '93 33' breakaway. Does anyone on site have the answer where I might look? While at the rally I contacted the Sparten people there. They said there is one, but were unable to tell me where.

have 94 30ft. Breakaway....tranny interface connector is located in 12v. electrical compartment next to driver near the top. good luck, bob

Did you mean the forward compartment below the driver?

At the top of the compartment under the driver I found a black rela box for the transmision, but no computer connection, anyone with any more info?

sorry, been away for a few days...yes I meant the electrical compartment below the driver..mine contains the allison ECM(computer) as well as the VIM module which powers up the inside shift module..adjacent to the ecm is the plug in for the interface...your ecm and vim might be located elsewhere...hope you can find it...bob
