got a lil problem. I have a 96 GT Auto, and i just got my 4.10's installed. Only problem of course is my speedo is WAY OFF..I have the speed cal and i had my god brother install it but he said he couldn't because the connector from the tranny is totally different then the connector from the speed cal and he said he really didnt wanna cut my harness. Anyone know what the deal is? I heard numerous people say they installed the speed cal in their 96-98's but i dont understand why i cant? This speedo is really pissin me off, n on top of that i just got a speeding ticket because i had no idea how fast i was really going. I need to fix this asap. someone PLEASE HELP
