Alright guys, I orderd these two items and have since changed the direction i'm going to run my compressors. Pretty much i'm going to run a solenoid rather than relays. I have 2 rolls of 20' each of power wire, and I only need one. The wire is Knu Konceptz KCM Red power wire. $7.00 + shipping. Flat rate should be about 5-6 bucks. ______ The distribution block is an interchangeable unit. You can use it for 1/0 or 4 awg on the inlet and either 4 awg or 8 awg on the output. I have 2 100 amp fuses to go with it. It was $14.99 + shipping new. I'll let it go for that shipped. LMK.
