How does a person wire in a two terminal cylinder shaped coil into our camaros that have 4 wires going to the coil. Does anybody have a digram on how thats done so that everything still works. I know that the pink wire is the supply voltage, is that 12volts?? What do the other wires do? One of them has to be the coil collapse signal.

I would like to use the MSD Blaster Coil 2 unless somebody has a better option, i'm all ears. I don't want the GM blaster, it doesn't last.

 

Might try this ->https://www.thirdgen.org/techbb2/sho...threadid=61358

TomP wrote a good set of instructions for this project. I keep this link handy because installing that coil is on my To-Do list.

Thanks for digging the message up, Dale! I was just about to do that.

A little addendum to that; if you want to be able to "go back to stock" if your car dies on the side of the road and you suspect a spark coil problem, you could use quick-disconnect crimp connectors. Here's how you'd do that, following from Step 5 of the message Dale dug up:

5. Attach PINK/BLACK of GRAY connector to PINK/BLACK of BLACK connector. Instead of soldering, twist the wire ends together, and slide a female quick-disconnect crimp terminal over the end... and crimp it on. I imagine you'd need a blue quick disconnect, for 16-18 gauge.

6. Attach the BLACK/WHITE of the GRAY connector to the BLACK of the black connector. Twist the wire ends together, and slide a male quick-disconnect crimp over the end. Crimp it on.

7. Use a MALE quick disconnect for the wire coming off the MSD's positive (+) connector.

8. Use a FEMALE quick disconnect for the wire from the MSD's negative connector.

On your stock connectors that you cut off, do the following.

9. Attach PINK/BLACK of GRAY connector to PINK/BLACK of BLACK connector. Instead of soldering, twist the wire ends together, and slide a male quick-disconnect crimp terminal over the end... and crimp it on. This is the positive side of the GM coil.

10. Attach the BLACK/WHITE of the GRAY connector to the BLACK of the black connector. Twist the wire ends together, and slide a female quick-disconnect crimp over the end. Crimp it on.

The reason for mixmatching female/male like this is so you can never get confused when swapping coils. Notice that both coils, factory and MSD, use a male quick-disconnect on the wires that will go to the factory harness. The negatives of both coils use female connectors.

Whew. I'm making all this into a tech article, by the way, I just need to wait for pictures to get developed.

 

When you finish the tech articale let me KNOW!! I believe I have the color changes also. I think on my 92 the pink wire and I think a black from the main harness and a white and a black from the cap, will check tonight. Sound easy and streight forward. No I don't plan on making the quick disconnects because I never plan to go back to a GM stock coil.

The GM coils are nice for about 2 weeks, then the coil begins to leak to ground and the engine begins to bog of the line and dies between 1st and 2nd and lack that getty up and go.

Does anybody know the applied stock voltage on the primary and what the voltage becomes on the secondary with the MSD coil.

 

What did you all use for mounting brakets and where did you all put yours?????

 

A person doesn't have to mount it straight up, in nascar they mount them on their sides under the dash on the hump from what I've seen right??

 

Some of the Blaster coils are oil filled... and the only way the oil can cover all the coil windings is if it's upright. if it can't be mounted sideways, I think it'll say so on the package. You could email MSD, too, to ask- http://www.msdignition.com . I have the Blaster SS coil, and made a bracket for it so it sits upright, where my heater box is. Oh, hey, I took a pic a while ago, here it is:

 

Ok I check the wires and I have 2 white ones, one pink and one big pink one. So do I just put the 2 pink ones on the + side and the two white ones on the - side. CORRECT??

 

Yep, appears that way! On my car (86), if you look closely at my black & gray connectors, you can see an "A" and a "B" stamped into the plastic. "A" of black connects to "A" of gray, "B" of black connects to "B" of gray. Like you said, pink is supply voltage, right off the ignition switch, +12 volts, so yah, it would go to + of the coil.

Actually even if you wire the coil up backwards, the car will still run. You'll just get less power out of the coil at higher rpm's. So if the car seems suddenly weak around 3000 rpm after wiring up the Blaster, maybe + and - should be reversed. Let us know how it goes!

 

Thanks TomP, yeah when I get time to go rewire everything again and find the right secondary lead i'll let you know. I think it's going to be a lot stronger then the GM blaster and the stock coil.

 

Tom,

what you do think about how lots of performance guys think the oil filled, can "points" type coils are much better than the epoxy ones like ours. [stock coil and your MSD coil]

Really? Never heard of that before. So... I guess I'll say it's bs! But, I guess it depends on what the coil's used for. If it was used in a race that demands continuous high-rpm use, it might be better to use oil-filled; it might dissipate heat better? I've never felt my spark coil after a drive, but I'd imagine it doesn't heat up too much. But... then again, most of MSD's hottest race-only coils are housed in epoxy- and I guess they'd know best!
