one thing i might add when it comes to wiring, as i have had to fix many times, and am in the process again as we speak, is practice terminating your connections using a QUALITY crimp tool before you begin. i can't stress this enough. every time i have had to fix wiring issues, it seems the tool used to crimp the terminals was the one that comes with the 2,367pc terminal kit from the elcheapo store made in lacheapistana. there are utube videos that show the correct termination process of almost all the common connectors in use today, so if a guy isn't familiar with how to do this properly, i strongly suggest you view some, then get some spare wire and extra terminals and practice. also, use quality heat shrink. it really isn't as hard to do correctly as some [most ?] think, and i find it kind of fun. what is not fun however, is chasing down someone's poor wiring problems and correcting things that shouldn't have been done in the first place.
Agreed. A good Klein 1005 or other crimp tool is key. Want good crimps, use uninsulated terminals, toothed crimp tool and shrink tube.
I have taken apart other suppliers relay harnesses and you can't believe the poor crimps, especially the chinese sourced product. Crimps that were done and don't even capture the wire or insulation. Had one kit where 30% of the crimps were not correct.
If you mess up a crimp, cut it off and start over. Nothing is worse than chasing electrical gremlins that are hidden under insulation and shrink tube!
For the OP, think through the electrical supply to all the auxiliary items and use relays. If using the mopar style charging system you have to be very careful where you pull power.
Weatherpack are great, but are limited to 20 amps IIRC. Some fans pull a bunch more than that. Most other items are going to be below that threshold. I use weatherpacks a lot on my stuff, especially ignition boxes. Can swap out a box to test another in under 1 minute...
