I have a 92 camry 5sfe manual that recently blew. So I am now swaping to a 1mzfe v6 that came out of a 2000 camry automatic with harness an ecu. What wires do i need to splise on park/ neutral switch

SOURCE: 1994 Toyota Camry automatic. All forward no reverse

are you sure it is first gear it is making when in 1. In park does the car lock up if you try to push it with the handbrake off. If not your problem is adjustment of the cable i.e. although the lever is in reverse the gearbox isn't.

i had the same problem there is a shift link cable that runs to the trans i think...the cable has a kink in it or somthing you need to go and buy a new cable for about $100 it will run alot smoother ..

there is no crank sensor on this vehicles 2.0L. If you have power to the coil, new coil, cap and rotor try this if not done yet>>>Unplug coil power first....Try pulling off the distributor cap, and make sure the rotor is spinning with the cam...If this fails to spin, inspect the entire distributor assembly. If it passes, Inspect all the power circuit and wiring to the dist assembly, if ok possible ecu. i recommend having a mechanic check it out!! Hopefully this helps...please rate...thanks

SOURCE: what wires do I need

The wires on the Transmission Range Sensor that control the ability to crank the starter are the BLACK/GREEN wire at Pin 6 and the wire at Pin 10 which is either BLACK/GREEN or BLACK WHITE depending on your model. (build - date and transmission type)

With all that said, I think it only fair to warn you that bypassing these wires will set codes in your Engine Control Module. It is not going to like it if there is power at pin 10 with the transmission in reverse or any of the forward gears. This may also cause your transmission to not shift properly because the ECM will not know for sure what gear you are in.
