Installed the MSD 6 and blaster coil I picked up at Hershey this past weekend. Just thought I'd provide some notes for those considering adding this onto their SC with the 6 pin CD box
I installed the box on the aluminum panel the original Bosch box was on. Installation was tight, it would have been much easier if I didn't still have the original alt. with the external voltage regulator taking up space on the panel. I will post some photos if anyone is interested. The coil mounted in the same bracket as the stock bosch coil.
I installed the MSD box by using spade connectors on the MSD leads and connecting to the original 6 pin connector so no splicing into the harness was necessary and it can be easily switched back at any time.
A short lead was made to run from the tach output on the MSD unit and plugs into the 6 pin connector at terminal TD, no adapter is necessary
The thin red wire is hooked to terminal 15 this is a switched 12V source.
The orange wire is connected to terminal A this is the positive coil lead (white wire for coil)
The black wire (thin) is connected to terminal 31-1 which is the -ve coil lead (brown/red wire for coil).
For the distributor trigger the green wire goes to terminal 7 and the violet wire goes to terminal 31d .This is important as if the car is hooked up the other way it will run but very badly, ask me how I know
For the 12V power I ran the heavy red wire from the MSD unit to the +ve terminal on the starter, the heavy black ground wire is connected to the ground lug behind the fuel filter and accumulator on the body.
The car was running very well prior to installation and I really didn't expect much of a difference with the installation. But, I must say I was impressed with the unit, I opened up the plug gaps to 0.045" as I believe is recommended by Steve W. The car idles and runs very well. I highly recommend this upgrade. I still need to order a new set of Magnecore plug wires from Pelican but even with the old stock wires right now the car is a blast.
