I need some opinoins here guys, I am at a loss???

I installed a MSD 6A and a MSD coil, along with the MSD GM harness. I have had trouble ever since. First of all I can hear a loud clicking noise inside th ecar, I first mistook it for valvetrain noise. But I now realize it is comnig from the passenger side of the dashboard, which is where I have the MSD mounted in the engine bay.
>>>is it possible that the MSD is causing a relay to click on and off either by miswiring or by creating a strong magnetic field.

I am also experiencing a voltage drop, the voltage gauge drops down to the redline, as if the alternator has given out, and the stock tach is spiking up and down like crazy.
>>>>>This sounds like a wiring problem is
the MSD setup to for a stock V8 tach

And last but not least the car is idling very high.

Other than all that the car runs fine, pulls hard and has no issues. I shoud mention how I have it all installed I guess. The MSD 6A is on the firewall where the A/C box used to be. I have the postive run to the starting motor and the negative run to a location on the firewall where other grounds are run.
>>> go to the battery as nasty said
It is a stock location on the passenger side of the distributor. The coil is mounted on the "new" heater box that I installed. But it is very close to the valve cover because of the length of the wires.
>>>> lots of guys have them mount on the engine so this shouldn't be a problem
Should I run the MSD the way the instructions call for, the postive to the postive battery, and the ground to the negative battery? Should I mount the coil somewhere else because it may be getting to hot next to the valve cover? Should I put another ground on the MSD? Another ground on the alternator or the battery?
Ya recheck everything making sure you have good ground you should be ok providing there's nothing wrong with the MSD box itself

I am lost, please help!!! >>>>>Can't help ya there lol
