I read your post about your 110 and tach issue.   I have same tach on my 2-88.   Ag express fixed it but I think I have a wiring issue on tractor side of it as it's still not working.   I'm looking to compare or get a picture of the ground speed switch wiring, I don't think mine is Correct and I can't find any info anywhere!   Please give me a call or email 860-508-8702.
