Mounting MSD

[Lew Silverman]

I think the biggest consideration is that you want to put the box in a somewhat cool location, William, away from the headers and the high-heat area under the hood. The two larger black and red wires have to be connected directly to the -/+ terminals of the battery to work properly, but all the other connections can be lengthened if necessary. Most of the installations I have seen mount the MSD box on a metal plate somewhere in the vicinity of the passenger side footwell, along with any of the other timing or overspeed accessories. You can also mount the coil inside as well, and use a pass-thru connector mounted on the firewall. This way everything is in somewhat the same area, out of the heat and easier to troubleshoot in the event of a malfunction. MSD has also come-out with a unitized relay accessory which will make wiring everything much easier.

I'll try to upload a picture of how I'm doing mine in the 'wagon. Maybe that will give you some ideas.

Good luck with your project!
