Battery Wiring Question

Ok so I am in the process of wiring up my car and was trying to simplify things as much as possible. I've already re-wired a '66 Mustang so the specifics of wiring I'm not Concerned about.

In order to simplify my wiring I am planning on getting rid of the starter solenoid and using my powermaster's internal solenoid for cranking the engine.

Now that I am doing that I want to know if I can run my Battery + as follows.



As you can see I have an MSD ignition box, Painless Fuse Box, RJM EFI Fuse box that all need Battery +. I want to run the cable from the battery to a terminal post under the dash and then out to the alternator, then from the alternator to the starter for the 12v needed. I think this is doable but just want to make sure everything will be ok as well as what wire sizes (ga.) I will need from the battery->Post->Alternator->Starter

Thanks.

Oh, Also As far as the fusible link needed for the alternator, should I put that between the alternator and the post? the Painless and RJM harnesses have their own fuses so no worries there. I'm guessing the MSD box has an internal fuse? not sure about that.

where's everyone been on this board? seems like there's been minimal activity here the last few days.

I'm normally putzing around in the garage trying to get my car to that point!

I like that setup too. I wasn't sure on Fuse size so I'll just use the same size you are. I want to run it through the cabin though so I can tap the source for my various harnesses I listed.
