Love the crimping tool, Marc.  Are you running a big ground wire from the battery to under the dash also?  I hope so, for the EFI box's sake.  Do NOT rely on a chassis ground for your ground to the EFI electronics.

Thanks Jay. I've been thinking that a ground terminal would be good idea but wasn't sure I'd need one. I will definitely add that.
Think 8g will do the trick?

I typically feed the EFI box directly to the battery with #10 wire.  So, I guess it depends on how much other stuff you will be running off the #8 wire.  If its the whole car, except for the starter, I would say #8 is not enough.  Have you thought about just running a couple of #10 wires from the battery and dedicate them to the EFI electronics?  That is the safest, surest way, along with a big capacitor across those two wires, right up at the EFI box.

I figured I would power the efi off of the under dash terminals.
I planned on using chassis ground for all the normal stuff like gauges. I think all I'll need the good battery ground for is efi and the Vintage Air unit.
Does the efi draw a lot of amps?

Wait, the efi needs constant power??

The EFI box will only take about 3 amps, but the injectors will take about 5, and if you run individual coil packs that will add another 10. 

If by constant power you mean when the ignition switch is off, no; the EFI box doesn't need to be hooked to the battery all the time.

Thanks Jay
Looks like I'm putting a larger cable in there.
Hmm carbs are so easy ;) JK
BTW I've been scanning the Vintage Air manuals and they don't give an amp draw anywhere.
I'm guessing it's prolly 20 to 25 amps.
Anyone know offhand?

This thread has only served to reinforce my belief that my sheet metal and fabrication skills really really suck.

thanks Marc :P   (looks awesome btw)

Thanks Drew
We all have our strong points. You've taught me a lot.
Any skills I have are mostly stolen ideas and screwing up and trying again.
I just hope I can get through this wiring mine field without hearing a click. ::)

Ok that was a bitch but all the main trunks are in. My problem is that I'm paranoid about juice so I run that damn plastic sheathing around all the hot cables as well as grommets. Makes it a bit difficult to run through the little areas that Ford only thought there would be 14g running.
I didn't want to run a bunch of cable but I was running out of amp room so I threw in another 8g wire as well as a 4g ground from battery to service the computer and efi stuff (thanks Jay). I'll put in a ground terminal next to the engine management which I think will I'll install in the glove box area. I'll fab a bracket to mount it all on in there.
So I now have 2 8g wires from the battery and 1 4g ground wire for important stuff. Chassis will of course be well grounded and service all the regular stuff.
So I figure I've got 80 to 100 amps of service to under the dash.
Starter will again run under the car from the solenoid in the rear. I think since it's a mini starter I can get away with 2/O so of course I'll run at least 1/O
Included a pic of how I ran the cables so you can't see them and a pic of how the battery tray is coming along.

OK, mocking up the battery tray after welding.
Welds not ground yet.
I'm thinking I want it anodized black so I have to put the holes in it then process it.
I remember when I worked at Cole boats we used to do this same process. Install the aluminum raw, then take it to the polisher then the anodizer and the parts came out beautiful and hi gloss.
As far as the layout here I'm thinking a 60 amp circuit breaker for each hot leg out of the solenoid and a 150 amp breaker between the battery and solenoid.
I like these circuit breakers. They have a button that you can push to break the circuit. I'm thinking they will be part of my theft deterrent system. Since I have two legs of power I split the loads. I'll run the ignition through one side and the stuff that needs constant power in the other side. That way when I park it I can pop the ignition side breaker and car won't start. Then when I'm back I just go to the trunk and click the breaker back on and away I go.
In the picture you can see the top breaker is popped off. See the little lever?

Now that I've been looking at it for a bit I might just do a brushed aluminum finish on the battery box.
Just thinking' out loud.

My Vintage Air kit came with a 30 amp circuit breaker.

Mine also John, so I took a total guess of a 20 to 25 amp draw.
