Hi I purchased an Intellitronix digital dash for my 91 Camaro,received the dash and the sender.Instructions vary basic , The problem is I want to use my VSS signal to ecm to prevent stalling of my tpi engine . the problem is their dash runs off their cable drive sender,which the 90 up camaros all have electric dash and use non cable vss sender. So I called them and they were vague on which terminal of the buffer to hook up to,finally decided that I should hook into the ecm connector on buffer, Did this didn't work tried the cruise and speedo out on buffer no work.Did test with their 12 volt powered sender didn't work speedo bad will send back they will fix . Has any out there used one of these dashes with the yellow buffer and how did you make this thing work using a vss signal to ecm. Thanks Mike
