not a problem mark what wires that come of the positive terminal
mark any wires coming off the negative
the
distributor wire to the coil is the centre one
just make sure the coil you buy is the same one is marked to be used with a resistor and one is not
buy the same one that as is fitted already to your car
if the coil is in a bracket with a screw holding it in undo the screw or undo the bolts holding the bracket to the body
just make sure the positive wires go back onto the positive point on the coil
and the negative to the negative
no tricks in doing the job your self
price supa cheap or repco is all about the same
