Is it possible to pull that off with a Ford Distributor?

Interesting thing about this one is I don't have the keys. Where do i put the 12 volts to on the box and or the coil to get it to spark? I only need it to run for 30 minutes to stop the car from being towed....
I have all new lock cylinders and keys but I can't "work" on it in the parking lot.
Hooking up a couple of wires would be ok according to security.

hire your own towing service to move the car...

or hire a locksmith to change the ignition lock cylinder..    they will probably ask for ownership verification of the car and a valid ID...   but thats easy...

i don't feel comfortable posting info on how to start a car without a key on the forums

MSD boxes can be hooked directly to the Duraspark II distributer with 3 wires from the side of the housing..    black is ground...   orange and purple are the signal voltage....

some MSD distributers use the same basic design pick up coil and reluctor...

on page 35 of the PN9615 MSD installation guide..

shows the magnetic pickup pigtail connects to the duraspark 3 wire harness..

the PN 8860 harness has a GREEN (-) wire that connects to the VIOLET duraspark wire.
the MSD harness Violet wire hooks to the ORANGE duraspark wire..

one thing.. one will notice that the smaller red wire hooks to the OLD COIL positive wire harness.. and the black and orange wires hook to the ignition coil...  thats because there is significant primary voltage on the orange and black wire..  this is why they are separated..

its also a good idea to add additional ground straps between the engine and the body..   and verify the battery negative cable terminal to the body connection is larger also...

failure to add additional ground straps between parts MAY result in damaged MDS or any other brand components..

and since you are not the only one reading this..   i will explain why..

the high voltage spark comes out of the coil tower.. thru the coil wire.. cap.. rotor , cap.. spark plug wires.. spark plug... cylinder head...  block or intake..   but how does it make a complete circle back to the MSD box thick black wire????  shorten that path.... with additional properly installed ground straps..

thank you for the clear and thorough answer. I will indeed make sure that my car's grounds are as beefy and short as possible when I upgrade the ignition to the MSD parts I have waiting on the shelf. I had actually looked up the directions and wiring diagram probably as you were writing this.
you are a font of knowledge and I appreciate your assistance.
thank you

i am thinking that you are working on a 70 distributer... and being way far out...  if you can find a duraspark ford V8 distributer..  but its the WRONG one.. don't worry.. let me go through a few things to convert point type V8 ford distributers to ford electronic duraspark units..

on the electronic distributer...  remove the reluctor by levering upwards with 2 screwdrivers to push it up the shaft.. don't loose the little roll pin...

remove the vacuum advance clip.. then the 2 screws holding the vacuum advance..  then the 2 screws holding the breaker plate to the housing..   remove the advance and then the breaker plate..

take a look down inside...   note that the ends of the lever have limit/ stops.. }0______{   the other will not have a pin in it.. one is going to be longer than the other.. thats the limiting device.. how many degrees the mechanical advance has is  on the flat plate..   you should try to find one with similar amounts to what your point type has...

under the push on rotor and under the felt pad is a tiny wire... J_L  kinda shaped like that ...  you can grab one end and pull upward to gently remove it.. or get in a pry it open with 2 small scribes..     you will have to remove the advance springs first.. DO NOT DAMAGE THE WEIGHT BUSHINGS..   i have NOT FOUND A SOURCE FOR THOSE YET..

you can take the point type distributer apart  and swap on the electronic distributers advance upper shaft... the breaker plate .. the reluctor ..   you will have to saw the round opening where the primary wire came through the side of the housing. to make it a U shaped for the pick up coil harness..

although the MSD diagram does NOT use the black wire to the ford pick up coil... i think i probably would..  and hook it directly to the big black ground wire into the msd box along the full sized power from the battery... so the high voltage actually has a shorter path to make the complete circle..

lets test the duraspark pickup coil... set ohm meter to 2K ohms... should read just under 1,000 ohms..  500 to 1,500 is expected...   before disconnecting.. flip the meter to 2 volts ac.. with it still hooked to the orange and violet.. spin the distributer shaft..  you need to see really close if not over 1.0 volts AC..     if it passes the resistance test. but fails the ac voltage output test.. either the gap is wrong.. or the reluctor is bad.. they do go bad..

i have posted this voltage drop testing chart on other threads... print it and use it...

it will really help you solve crazy hard to find issues on cars..
