My current speedometer is an electronic unit, powered by a module that plugs into the Ford T- 5. I am not sure what I need for this 904 to work it. As it sits there is nothing in the hole in the tail shaft, so suspect I need something as a Mopar base that a conversion module plugs into. Any ideas? I will call Summit maybe tomorrow. Thanks. Sam |

Sam on my 83 D-150, I changed it to an instrument cluster from a 90 D-150,. The 90 cluster has an analogue speedo driven from a VSS, no speedo cable.. the standard motor products sc109t, http://www.rockauto.com/catalog/moreinf ... cc=1084766 screwed directly on to the existing speedometer pinion drive housing on the 83 a833,,the 904 tranny uses the same speedo pinion drive housing. At least the ones I have seen in the local pull a parts do.. here is a e bay ad for one, I bet you can also get one from Brewers or Passon http://www.ebay.com/itm/Mopar-Dodge-Ply ... 1371wt_718 I believe you will need the sc109t or alternative that matches the pulse needed by your electronic speedo.., the tranny speedo pinion drive housing, as well as a speedo gear that matches up to your axel / tire size. the nice thing about going electronic on the speedo drive is from there it is ez to install a cruse control package,, as the cruse control can run off the same signal as the speedo. |

That should work, when I set mine up I just bought an Autometer ATM-5291 from Autozone since it was recommended for my digidtal programmable speedometer (mopar didn't make a speedo gear for my combo so I was able to use what ever gear i had handy in my A-833OD and still know what the 4.56's out back were really giving me on the street). -D.Idiot |

Thanks for the replies. Hopefully I can figure that out. This speedo is calibrated on a measured mile, so the gear drive does not matter. I would like to be able to use the harness I have currently. I will have to check that out and see what it is. If not then splicing wires is not too hard. Thanks again. Sam |
