i just bought a used MSD Balaster Ignition and do not have the owners manual to hook it up, does any body have diagram, i look in tech pages they have msd 6a, however mine does have extra wire,

can anybody point me in the right direction to get the wiring diagram for this unit?

MSD's website has instructions for all their products you can download.

thanks, i will try there

ok, i have the diagram, now i have a stupid question, it shows the connector to the dist. hookup, the white not used, the red to the positive on the coil, the orange to the ground of the coil, and a 12volt wire coming from the ignition to the postitive on the coil and i am done, my question is what happens to the ballastor, what happens to the voltage regulator?
and the ecu box, do i take all this off when i put the MSD 5900 blaster on car?
:

okay, i have it hooked up and took all the other stuff off the car, i do not know why i went with all the other stuff to begin with

u need the voltage regulator...the ballast can go along w/the ECU. some use that stuff as back up tho I took it off and never looked back.

get the Denso alt THEN u can ditch the voltage regulator. I did and it's great!

when installing MSD with a stock harness. a good place to hook up the key power, small red wire, is to the blue or brown wires leading to the ballast. then jump the blue wire to the brown. the blue wire has power at the key on position. the brown has power at the key start position. when hooked together you will have power at all times the key is turned on.

so i have to keep the volatage reg. hook up?

In case you need help with wiring click the thumb image and then click the enlarged version.

Do not disconnect the voltage regulator unless you are changing your charging system. You do need your regulator.

Are you wiring this under the hood or under the dash?

i think that i am going to mount under the dash and leave all my stock ign in place,

If you do not disconnect the wires from the resistor you can grab either the Blue with the tracer or the Brown wire from the ignition switch. These wires lead from the ignition switch to the middle of the bulkhead at the firewall.

Now remember this, if you remove the wires from the resistor you must connect the Blue with the tracer or the Brown wire together.

Otherwise the motor will fire up only when cranking or only when you let go of the ignition switch. Not both.



Notice these wires do not go to the fuse box.

im planning on taking the resistor out and soldering in a piece of wire in its place to use it as a terminal block, and hooking my switched power there.

thanks for all the input, i am going to try it out tommorrow , i spent most of the day today, putting the console and shifter in,
