Wiring diagram help?

Good morning-

I'm working on partial automation of my brew rig (HLT and MLT) but am finding the wiring to be a unknown and therefore stumbling on it.

I understand the basic concept and purchased all the parts, but think a wiring digram might be a great reference (troubleshooter?).

Anyone know of online/dead-simple way to put diagram together?

FYI - Brewtroller, 4 SSR, (2 pumps, automated/pilot LP on banjo, 120V heatstick)

I've only used SmartDraw and AutoCad but I found both to fall short in simplicity. I think pen, paper, and a scanner would be the easiest method to visually represent your wiring.

if you have access to Microsoft Visio (I think they have a 30d trial) they have a "decent" electrical template to futz with...at least I have been.

And people around me think I'm brilliant designing all this stuff...which to them is our new datacenter...but really my rig plan
