msd 6 install questions
 

installing an msd 6a and blaster ss coil in car in sig. i want to mount it on the driver's side fender brace behind the battery, on that 6 inch piece of metal with two 8mm bolts on it, on the front driver's side near the horn. is this a good spot or can water be a problem here?

questions for the electrical hookup for the msd:
large red wire = (+)batt terminal or (+)starter solenoid? which is better?
large black wire = (-)batt terminal or ground elsewhere? which is better?
orange = (+)coil
black = (-)coil
red = switched 12V source, whats a good source?
white trigger wire = whats a good source?

any specific wires that are good to tap into would be a big help

magnetic triggers:
violet
green

i know that i dont need to use the magnetic triggers, but i wanted to set up a kill switch for the msd. can i simply extend the violet wire, attach to a switch, then from the other end of the switch run a grounded wire? when the switch is open and the msd's violet wire is grounded. i believe this will safey disable the msd, causing the car not to start. make sense? can this cause problems?

well for the kill switch.. i ran the large red wire to a switch , then from the switch to my positive battery terminal i f i remember correctly... this way the switch has to be on to allow power to the box.. but i am sure there is other ways of doing it.

Re: msd 6 install questions
 

i thought about that too, but was concerned that a switch might fail due to the larger amount current going though that wire

This is where mine is installed:

I DO plan on cleaning up the wiring someday. To me, it does not seem like a good idea to install it in the inner fenderwell.

questions for the electrical hookup for the msd:
large red wire = (+)batt terminal or (+)starter solenoid? which is better? I used Starter solenoid
large black wire = (-)batt terminal or ground elsewhere? which is better? I gounded elsewhere

violet and green go to your distributor. If you want a kill switch, just ground the white wire, no spark. I wouldn't run either the violet or green through a switch, keep those as short as possible.

Source for the small red wire is your ignition switch. When the key's on, find a hot wire and tap into that.

Run the big red through a fuse to either the solenoid or the battery, not much difference there.

Big Black goes to a good ground, again doesn't really matter where.

MAKE SURE you mount that box with the rubber isolators that came with it. It'll fry soon if you don't.

u sure about the violet and green to the stock distributor? i was almost certian i had to use the white wire...........

how large of a fuse should i put inline with the red power wire?

guess i need to make some isolators, cuz i dont have any........

FWIW, in my 1989 gt I used the red with light green stripe as a switched 12v source. It is in the gray plug by the master cylinder. I used one of the blue splice connectors to make the connection. I second Jester about the pickup wires. Do not use the white wire. I can't tell you exactly which wires to tap into at the distributor though. You can look at some wiring diagrams on MSD's site if that helps.

Absolutely 100% for sure violet and green go to the distributor. Also 100% the white wire isn't used in your application. But, if you ground it you'll have no spark. Instant anti-theft switch. ;)
