Yesterday I was able to work on the car for about an hour. All I did was pull the carpet back and add some additional electrical tape to the wires I tapped into to ensure no conductors were exposed. The sync problem still remains however
My next plan is going to be double checking some settings in TS. If that doesn't fix it, then I am going to double check the ground wire, and maybe see if I can't improve that. Then I will rehook up the stock ignition wire, and see if the sync issue goes away. Then just keep working my way back trying to figure it out...
