I wired my car with a roll of number 12 multiple strand hook up wire and a seven dollar six circuit fuse center...The fuse center cost me seven dollars. I can't remember how much the spool of 12 was, but not much!
When I got done wiring all the stuff in the car, it turned out I had created a really huge rats nest of wires up under the dash. And I was figuring to add some more wires for Air conditioning and maybe remote trunk or electric windows or so on and so on.
So I spent a ton of bucks on a "Kit" of stuff to re-wire the whole car. During the process, I video'd what I did, put the vids on Youtube. To see them go
And look for "Rewire job, step one"...then watch all the videos till "Rewire job, step eight".
If you are planing to re-wire your hot rod, the kit's offered by Centech are quality parts...but the instructions will leave you scratching your head a bit. There are a lot of parts, and my "kit" instructions contained lots of different instructions instructing various ways of hooking up various sections of various parts...and no example "whole car" electrical diagram.
My magic heater door quit working today. So I took the assembly off the heater and fixed it. A screw had fallen off....the screw that held the motor actuator arm to the door actuator arm (?).... Anyhow, for thems of youse who would like to have an electrical heater door...here is a video describing some a the parts yer gonna wanna get maybe?
PS Note; The motor is a dc motor where by reversing the motor can be done by switching the two wires that power it. Think of electrical current going in one wire and out the other. Diodes only let current go in one direction. Limit switches "limit" physical movement by opening an electric circuit. Once the circuit is "open" it can be sort of jumpered shut for a revers direction of current by using a diode to steer the current over or around the switch contacts. Cool a? yup yup yup.
hope the above link works. Me steering 39 Pontiac with "new" power steering. woo hoo! Finally done!
...so, now what? guess I will work on air conditioning?
Oh, for thems of yous who have a 56 Cadillac power steering box; That screw at the end of the Pittman shaft that looks like it just makes end play go way....it also makes the slop betwixt the rack gear and the Pittman shaft gear go away too. That reduces to zero the slop in yer steering. WOO HOO! What a great power steering box! Works like a champ, now even better!
