81SC - need help with rear fuse wiring
 
I have an 81 that came without the metal mount that holds the CDI unit, Defroster Fuse, and the engine harness plug. I had to source all the bits and pieces from scratch to put all this together. In any event, Im at the point where I have to wire up the 3 block fuse panel. Can anyone take a look at how this is wired up on a stock setup and hook me up?

the wires I identified are as follows based on the picture and how I was positioned:

Left Side: big red wire and a little red wire

Right Side: big red wire, red with white stripe, red with black stripe, blue with yellow stripe

Thanks!

I'll try and remember to pull the cover off my 82 when I get home.

If I can get down my driveway!

Read 70+" snow in last 25 days..
This is before the 24" we got this past Monday.

One of those red wires on the left side of the fuse panel in the picture above is constant power and the other is switched power. I'm pretty sure the top (with the copper bridge to the middle fuse) is constant and the bottom is switched. You'll have to put a voltmeter on them with the car off to figure out which one is which.

so from the pic, it looks like Big red to top, little red to Bottom on the left side. But the big kicker here is constant vs switched...constant on top.

and it looks like Big Red to the top, red-white stripe middle and the other two bottom...on the right side

does that sound about right?

In case you didn't see one there should also be a short 6" brown ground wire from that aluminum consul to the ground stud
