The MSD Thread.

So from what I have read so far.. I out of luck adding the old MSD 6200 6A that I had in my parts bin into my 91 Ram 50.

According to the instructions I could trigger it with the Negative line that would have went to the coil.

I am trying to date this box and the transistors have a 9304 date code so I'm assuming 1993, 4th month

Thread resurrection time!

Is there a walk-through or wiring diagram for running a MSD Blaster 2 coil without using an MSD 6A box? I'd like to drop a 6A box in this truck eventually, but right now I'd like to do this as (cheap) simple as possible. I'm wanting to run the stock distributor if possible or a modified stock distributor if necessary, go as simple as possible with wiring and try to get the truck running proper with the least amount of fiddling and hassle. I've got the stock ballast resistor, a (bad) stock coil, and all of the wiring is still there. Can it be done and function properly without smoking the stock ICM?

geezer???
Please do chime in

I wish I had some input on the MSD6A. The only time I've upgraded my ignition was swapping a stock coil for a Bosch T-coil, 8.0mm stainless steel spiral wound leads and performance plugs. It was punching out about 40kV to the plugs and seemed to work really well but I didn't have anything to compare it against personally. I do know there are fake MSD's lurking on the net - dry/transformer type coils are cheaper to get and were fitted as standard on Mitsubishis, so I don't have to stress about resistance values or cooking something. I actually bought a Diamond brand recently (which is a Mitsu unit and I got it insanely cheap here in Oz from ebay) for my truck and I'll be getting decent leads, plugs and a new noise suppressor soon.

I'm sorry, I'm basically clueless here. I never got the chance before now to get into the details of an older vehicle, so I'm just trying to figure out what wires go where and what plugs into what. I know the bare bones basics, but a nudge in the right direction to some literature that explains everything would be hugely appreciated.

I still have more reading to do in the wiki section here, and I have a lot to learn, but that's kinda why I'm asking so many questions.

despite the odd looking coil in your truck, it still works the same as a blaster 2 coil. I have to pull out a manual to figure out the wiring for you, or go to the manuals section and look for yourself.

I'm looking for it myself, I realize I jumped the gun here but I'm really glad there's experience on here, because I'm dumb and rush headlong into things. All the time.

I am going to get a 0.8 ohm ballast resistor for the Blaster 2 coil, because that's what the documentation says it needs, so that's what I'm going to try and find.
