Hi,... I have a 2000 Silverado 1/2 ton. I have been searching on here and found out how to wire my 241 after I had taken out the 246. All that was needed was to buy the right plug from GM and splice in the Green and Purple wires. I tried this and got no results. I can start the truck up, but when I shift into Drive and give it gas it won't move. The 246 had 3 VSS plugs with the green/purple wires and I have tried all of them. This is my DD so I need to get it back up and running. Let me know if I did something wrong or if you have more info... Thanks.
