You obviously don't follow many threads on wiring kits on the different mopar boards. Hell even with motors I see mopar guy spend 10k on a motor only to cheap out on a converter. I see the cheapness all the time with all kinds of parts. .
Most of the mopar people i know here wont drive their cars in the rain, or even every day so weather proof stuff isnt a major issue down here .
Unless your only selling to show cars in Fla your going to have to make connections weather proof. Otherwise you lose a bunch of potential customers or worse yet get bad mouthed all over the net when some chump buys your unprotected harness and has problems because of corrosion at a non weather proof connection.
I'm not trying to bust your balls here but if your going to do this at least do it right.
AS FAR as the so called average installer goes . If he can't or won't buy the proper tools to install the kit properly then in reality he probably shouldn't be rewiring his entire car anyway. If someone is going to half *** an install they are just asking for problems.
The only other way to do it is make it 100% plug and play. Not sure if its even possible and if it is up goes the price.
You are the one that has to decide on what to build. A nice harness to be proud of or a cheap pile of Crap.
