I am currently working on a 93 civic dx automatic and am running into problems with the wiring. I first of all keep getting a code 8 ( TDC sensor ) which i have replaced the sensor and also tried a brand new dizzy and keep getting the code. I have also traced the wires and they are all in the right order.

Also does anyone have a wiring diagram on how the 4th plug at the ECU should be hooked up. I believe its for the GSR auto tranny. The ecu is a P72 and has 4 ECU
plugs and its OBD1 by the way. There has to be someone out there that has successfully done this swap and just need a little help.

BTW the fourth plug at the ecu has the same color wires as the cky and tdc sensors.
