Re: SD harness from manual to automatic
just guessing was your car tbi before ? You can stip the wiring off your old harness. tcc lockup consists of three wires to the transmission for tcc. from ecm and 4th gear switch. The brake switch goes through c100

You wouldn't use the wires that are on the sd harness for the vss going directly to the ecm but instead the tbi wires that go through c100 to the vss buffer. You can un pin b9 and b10 those would not be used but the vss input would go from the buffer to c6 and the output to the speedometer is b11

All the changes I listed will be made at the ecm. You will want to check for differences at c100 and c201.
