HH - Agree with all above well wishes, and sure you may be tired of that at this point, so I'll move on - but hope you're well and happy.
I have a 74 - so you know the area I come from on your first post with the differances. I had no fuse box, but do have a adapted GM style colunm.
The column was not hard to adapt to my EZ wiring harness I got. Should be similar to the Painless. EZ sent adapters to the stock GM style plugs too. Since my GM Column was hacked in by the PO - all the original wiring plugs were gone so I got the new plugs and re-wired it in the the adapter. Fit together nicely.
The advice I have for everyone with the wiring is the same no matter what the kit type:
1) Write down ALL the electical components you have on your jeep to supply power too. I combined stuff slightly - ie Head lights vs right head light & left headlight, but you get the point. I also decided to plan for all future circuits I would need power supply from the fuse box - and made sure they were routed the right way. (IE my electric fan upgrade one day will have a water crossing kill switch - I already have a switch and power lead ran on dedicated fuse positing in my block, although the actual remaining wiring will still need to be done later)
2) I choose a location for the fuse box mounting (if different than your stock location)
3) I go through the cirut lables on the fuse box and chart out what each one will be for. I take into consideration first what is already labled correctly (IE headlights, turn signals, radio, ignotion, etc) for ease, and make sure with the fuse box placed approximately where it goes all power supply wires look like they are going to the correct loom portion (usually the harnesses have 3 looms - Engine compartment - Interior - Under / rear - Some of them break out further obviously but consolidation is cleanest to a point
) then redistribute any circuts to the corrected looms. For example, I chose my fuse boxe's Fuel injection circut fuse slot to be my CB radio circuit. So I removed the wiring necessary for from the engine compartment loom and fed it through the interior loom. If necessary I pull the wiring from the rear of the fuse box to incorporate the correct legnth wire to be cut to fit (you don't want wires too short everywhere with splices - this is why you bought new harness
)
4) after that slightly teadius task, I mounted the fuse box and ran the looms in their general direction.
5) clean all grounds and add new ones as needed / desired to hook components to as you go - or Like I wired in all my grounds now - from every circuit. Then I could add those wires into the looms where possible / needed for final clean routing with the rest of the wiring.
6) From here I took each loom and ran the wires for each circuit to their general place (took the wires to general areas, looped same ciruit wires together with loose knots / tape).
7) Then I started, one area at a time (depending), making sure all the looms were tucked and positioned where I wanted them with protection and "almost permanant" mounting - closest to the fuse box out. The more complicated circuits I would finish all at once even if it meant moving back and forth from the engine compartment to under the dash, just because I was already thinking about all the deails of the circuit, but for the most part, working by area from fuse box out allowed me to keep everything very clean and tight as I went with LESS breaking back into the loom to add a wire or move one etc.
I just took my time, made each connection nice and shrinkwrapped and it went "fairly" smoothly. I actually leared a lot about my jeeps wiring too as now I have wired everything on it.
