So today I finally took the plunge and ordered a Performabuilt TH400. I am doing research and getting parts together for the swap. My biggest question is for the speedo right now. The TH400's that Performabuilt sells has provisions for the VSS and has the the reluctor wheel as they are newer generation TH400's, can I just plug in my stock VSS harness into this sensor and have my speedo work? I read in the sticky about using the WSS for the 350's but it doesn't mention the 400's. Who has done this and did it work for you? Thanks in advance.

 

bump I would like to know.
