The blue wire is usually just an auxiliary wire. The blue wire does not need to be connected. Tape the end of the blue wire off.

white wire to black and yellow to blue
Connect the green wire to the bare wire in the junction box. Connect the white wire to the white wire in the junction box. Connect the black blue wires to the black wire in the junction box. The black is usually the fan and the blue is usually the light on the fan. They seperate them in case you wish to hook the fan/light to two switches.
There are 3 (maybe4) wires on your tachometer. One +, one - and one gives the signal to the rpm. You must connect this third wire to the ECM (ECU) rpm outlet (White wire) or directly to the ignition coils negative wire (blue - yellow) If there is a fourth wire on the rpm, that is the backlight. Connect it to the dashboards backlight system. Good luck.
the green is the signal wire and it goes to the negative side of the ignition coil

Connect the trigger wire to the yellow/blue wire that is joined to the Blue wire from the coil. Don't use the yellow blue at the coil, the connection you want is a junction point where the blue meets the yellow blue. It is at the plug that hooks to the coil. Just connected mine and it works fine - 2.6L 4 cyl. Connect the trigger wire to the at the Blue wire from the coil. Just connected mine and it works fine - 2.6L 4 cyl.
