I am installing my MSD SCI and blaster SS coil. I have the postive and negative connections made, I have the blaster ss coil connections made. I have two wires left on the MSD SCI and three wires from the stock coil mount location, sooo what goes where?

Doesnt anyone have an aftermarket ignition system?!?

Almost done now for the wireing...

With the hardest part out of the way and both units mounted the wireing is the easiest part.
.**THIS WIRING IS CORRECT***

MSD SCI THICK RED->Battery Positive
MSD SCI THICK BLACK-> Battery Negative
MSD SCI THIN ORANGE-> SS Coil Positive
MSD SCI THIN BLACK-> SS Coil Negative

MSD SCI THIN WHITE-> OEM coil Blue wire ( Ground )

** You'll need to use the "Y" splitter provided by MSD**
MSD SCI THIN RED-> OEM coil Black w/yellow stripe , & Yellow wire


I cannot stress the importance of soldering all of your connections and using heatshrink tubing or electrical tape to seal them when you are done. Loom all of your wires to protect them and keep them away from shap metal of hot objects that may melt them.

I have some concern about the spades used to plug into the OEM Coil Harness. If I can configure a way to secure them while plugged in I'll update this how to.

All done
