Ok, I'm trying to install this Mallory HyFire 6A ignition on my 94. I found (in a search thank you, lol) a wiring matchup. stock red/black to this, stock blue/yellow to this...and that's all great.

But than it says I have to hook it up to the + and - on my leading coil? I have the damn thing in my hands, where's the + and -

Please help someone who is still learning out!

-Thanks!

 

Ok, nevermind...duh...

I just need to figure out if red/black is positive or blue/yellow.

Anyone know that?

 

Just for future reference:

For the leading coil, simply clip the wires on the clip leaving yourself enough wire to solder to the clip and to the cut wires.

Solder MSD Red to Stock Red/Black
Solder MSD White to Stock Yellow/Blue
Solder MSD Orange to Stock Red/Black on clip
Solder MSD Black to Stock Yellow/Blue on clip

If your yellow/blue is like a coax cable (silver ground wrapped around) make sure to peel that back cleanly so it doesn't touch and ground the thing out. (this didn't happen to me, I read about it in another thread)

Run wires neatly throughout car...put car back together, cross fingers and turn on key.

Actually, I did notice I could have done this much faster had I removed the elbow and throttle body instead of the entire manifold extension (which is what the shop manual shows to replace a coil).

I have noticed improved power from this upgrade. I do need to check my a/f ratio (luckily I was tuned super rich before this was done).
