Recently purchased coils from4in1.com and both coils have 1 blk wire and 1 yellow wire. The store told me that the wires can be attached to either terminal since the there is no polarity. Here's my question: the old coils have 1 blk wire (on the 1&4 cant be seen in pic) and 1 white wire on rhe 2&3. 1 orange wire connects both coils. how to wire the new coils???

My guess would be to treat the black wires on the new coils as the black and white wires and the yellow as the orange wires
 
Just had a look at mine and the wires are white and orange on both! I seem to remember I joined the white wires together then connected them to the black/white wire in the harness then the other orange wires were connected to the blue and yellow wires coming from the contact breakers taking care that the correct coil is connected for 1 and 4 and 2 and 3 cylinders, hope this makes sense?
