im confused about the speedo gear housing do you just put the same one in that comes out of your t case? i have an older mech one with the round 4 prong harness that comes out below the cable in the other hole. i found my sye kit at a junkyard and its brandnew out of a mid 90s xj with the newer style speedo housing with the 3 prong connection. im realy confused about what i should do about this.
