in regards to 1KZ-TE wiring you can modify the injector pump to get rid of the ECU because in 1993 to 1996 the engine was available in Europe with mechanical injection so the engine was designated 1KZ-T then the only wires you need is for tacho pickup and fuel shutoff solenoid on the pump in july last I replaced my 2.8 turboed diesel with a 1KZ-TE which I took the electronic controlled pump off and got the 2.8 pump overhauled and changed to become a 1KZ-T pump the most expensive bit being the distributive head ( the steel end which the 4 injector pipes come out off ) which cost $900
