So here's how I wired my matchbox in my 521 master chief, if its wrong then... shit thats weird because my truck starts and runs everyday..
First I got a bigger coil, I grabbed this coil from a 68 620 from a junk yard. This year 620 should also have a HEI dizzy if you cant get your hands on a matchbox.
You can see some wires, don't worry about these right now just get your bigger coil on and your new dizzy in as well. Again this is for a "Matchbox" not the HEI.
Get your engine to TDC and remove your old dizzy, lets hope you followed your book when putting in your oil pump, heres the bottom of the matchbox
you can see in the middle there is a small, side make sure this small side is on the small side of your oil pump shaft or whatever its call. it's in your hainz book, don't got one get one.
heres the matchbox and my cat 'Catface'
You can see that it has tabs, this one doesn't have it but there should be a black connector thing like this one,
Next remove this wire
Put that black and white wire here.
with a new tab the you found some where you then want to connect the red wire where it is seen in the picture + side of coil, and do the same with the gray wire to the - side of coil.
the + needs three tabs or one with two sides like i had.
And theeeen the matchbox side.
this picture the black/white wire under the coil is WRONG. just so you all know. do what I say above, not this photo.
red wire to black/yellow wire, gray wire to gray wire. make sure your black box is not facing your block, you want to have it facing the front of the truck, doing this however you'll have to change your spark plug wire rotation.
Oh shit!! I forgot You want to get a bigger cab and rotor for your matchbox but i cant remember for the life of me what i got.
can someone help with this part? I hope thats everything
heres how is should be now.
if you need any help then ask away.
hope this helps though there is more then one way to wire these things this way does indeed work.
anyone please add if i missed something.
