i am probably one of the only ones who prefer to make my own, one wire at a time, buying quality components, then "digging in".

I could build my own, I worked 33 years in the telephone industry customer service department doing prewiring of homes and businesses and installations of phones and key systems. I have A.S. degree in electronics but I'm 79 yrs old now and looking for a easier, quicker way to get this project on the road and drivable
The big thing is trying to remember what gauge wire to use on each circuits and trying remember how many watts are require to operate those circuits
It will have electric windows, heat and air conditioning, electric seats, no heat or cooling on the seats though and a decent stereo system, nothing fancy or loud
I'm thinking of using 85 to 100 amp single wire alternator and individual as needed relays for each circuit Time to start the pursuit and research

"Unless it's a Mopar" story of my life. I don't understand why all the big vendors have always gone out of their way to exclude us forever now. .. [censored] at its worst
