Disconnect negative terminal of battery.
Remove positive lead from starter solenoid.
Remove the solenoid wire (brown).
Remove two bolts holding starter to bellhousing.
Lift starter out.

connect a fast light to the positive side of the battery, then touch the negative side of the coil. have someone to start the vehicle to see if the light flashes. if it doesn't flash the you need to check for broken wires or bad connections to the distributor. if it does flash then the good coil isn't any good.

It should be black,but look on the coil,and it will have a negative sign in the coil next to the terminal like this - Now this terminal,will go to the ignition.

If you have a good look at the coil, it should still have a positive and negative sign on it somewhere. Try not let the extra wires confuse you too much. These are for the ignition module in the distributor. let me know if you need further clarification after you've had a look.

first you need to find the coil wire going into the coil on the + side and splice the white tach wire to that and the rest you can probly figure out ground/positive/night light dimmer/
