    Ok here were i am lost it tell me to move C1 and C2 to B10 and B12 but there a wire in B12. Do i just de pin that one at B12 and let it lay there??? I found a link said some cars have the wire there and its one less thing i have to do.

    also i found a link that tells me to use b2 and b11.

    Best Method To Do This:
    -Pins B10 and B12 are empty meaning there are no wires going into them as a general rule, however some models have a wire at B12 (if you have one that is one there that is one less wire you will need to move).

    -Pins B2 and B11 have wires going into them but they are not used for anything (weird, but trust me on this one).

    -Take the pin/wire from B2, depin it (this means pop it out of the plug) and pin it (pop it into plug) into B10's empty spot, how you have a wire at B10.

    -Take the pin/wire from B11, depin it and clip it into the B12 spot, now you have a wire at B12.

    -Cut the orange C1 wire and white C2 wire "in half" (by cut in half I mean cut the wire making sure to leave enough wire so you can strip and solder them to another wire later). Now when dealing with cutting I will refer to the side of the wire coming from the interior harness as the harness side, and I will refer to the side of the wire coming directly from the ECU's plug (direct ECU connection) as the ECU side (the only plug in question for this step is the ones that go into the ECU).

    -At the ECU plug, for C1 and C2 solder and heatshrink wires to them and run them into the engine bay (I did this via the A/C grommets). Mark these wires with a piece of tape saying C1 and C2 on it. Because if you are like me you were using black wire which all looks the same so you need to make sure you know which is which.

    -Now connect and solder the ECU side of B10 onto the harness side of the orange C1 wire, then do the same for the ECU side of B12 and the harness side of the white C2 wire.

    -Cut wires at A3 and A7, solder and heatshrink wires to the plug side of A3 and A7 and run them into the engine bay, make sure you mark them. Now you should have 4 wires running into your engine bay.

    So i dont have to pin the c2 wire into the b12 spot if the car already has the wire at b12. So just de-pin c2 and let it lay there right and run two wire out of c1 and c2 to the dizzy. all it say is one less thing i have to do dont realy tell me anything about that wire in the b12 that some car have and some dont.

    if you have a wire at b12 the cut it at the ecu and leave enough to play with, then cut the c2 wire and join it to the bit of wire left in b12 you should be left with a short bit of wire coming out of c2...

    i de-pin no cuting for me i just want make sure that i move c1 and c2 over to the b10 and b12 spot. One link tells me to and a nothere link tells me if there already a wire at b12 than thats on les thing i have to do just want make sure what would be the best way be for doing this. They dont real go into what to do if there alreay a wire there just says one less thing to do.

    well if you know where the other end of b12 is then you will need to wire it to your dizzy where the other end of c2 is
