  • Wire a JZA70 1JZ-GTE into a Gen 3 GZ20

    Wires to run the car:

    Engine side
    Dash side
    Thick black w red trace
    Thick black w red trace
    Thick black
    Thick black w orange trace - Coil and injector 12v feed
    Thin yellow, silver dots
    Thick yellow w blue trace - Fuel pump
    Thick grey
    Thin black w orange trace (ignition/acc switch)
    Thin green, silver dots
    Thin green, silver dots

    Thin black
    Thin black - Tacho
    Grey w green trace
    Grey w green trace - Engine check light
    Yellow w green trace
    Yellow w green trace - Water temp sensor
    Those last three are just extras, only the first five are needed to run the car... theres also one extra wire which is your starter wire but I have run my own start wire to a start button so you'll need to trace the correct wire back from the starter signal terminal and join that to the (I think) thick black with white trace wire on the dash loom side.

    Also while tracing the dash wiring functions, we made these notes, but as I said its pretty much just colour matching.

    Dash loom side
    Red w black trace - Reverse indicator
    Yellow w green trace - Trip meter
    Pink - Speedo (and trip meter)
    Purple w white trace - speedo wire, also activates dash
    Yellow w black trace - oil pressure light
    Black w yellow trace - speedo wiring, activates dash
    Red - Park light
    White - Neutral light
    Purple - Drive light
    Grey with gren trace - Check engine light

    There are three wires that come from your digital speedo sender, connect these up to the same three coloured wires on the dash loom (this is assuming you kept the original z20 soarer digital speedo sender and screwed into your new gearbox)

    would the mz21 be much different?

                    Ok,

                    Fuel pump relay, the jzz30 works differently than gz20


                    What do you mean by "bridge" the fuel pump relay?
