B3B wiring harness rebuild project

[bkahler]

I'm gearing up to make a new wiring harness for my 51 B3B. I've opted to not buy a new harness from YnZ or Rhode Island wiring. I find it hard to justify the cost. Also I feel I'm capable of making a new harness that looks similar to original.

Since I'm working out in Pasadena for a while I stopped in at YnZ's store to buy wire and connectors today and walked out with $250 worth of the same . The wire is similar to what was used on the truck originally, namely lacquer-coated braided wire.

For those of you interested in the project I've uploaded my worksheets in PDF format. http://www.141.com/dodge/b3b-wiring-harness-details-rev-1.pdf. The pages are in 11x17 format.

Without the information provided by Allen Parkhurst and David Erb located on the http://dodgepilothouseclub.org/know/wiring_harness/wiring.htm I wouldn't have been able to develop my worksheets. Many thanks for their willingness to take the time and effort to provide the information for the rest of us .

I've taken the liberty to change a couple of colors, mainly for the tail light wiring where I wanted the turn signal/brake light and the parking light wire colors to match modern day vehicles. I felt that would make it easier if/when I add a hitch to the back of the truck. I'm also adding in turn signals like Allen and David did and I'm also including a wire up front for powering some original fog lights.

I may also include a few wires into the engine compartment for an A/C compressor. Living in the south for the last 8 years I've found that having A/C in a vehicle is immensely better than not having it .

One drawback to buying the wire from either Rhode Island Wiring or YnZ's is you have to buy a minimum of 10' for each color. In some colors I only needed 20" or so.

I'll add to this thread as progress develops.

Well like everything I do I made a couple of mistakes in my wire length calculations so I've temporarily removed the wiring harness worksheets until I can get them corrected. I'll try and get it redone early next week.

Sorry about that

It sounds like you and others have done quite abit of work putting together this information

But

I can't get to the pdf's that you posted I get " Page Not Found "

Hope you can get it to work

Thanks

Albert,

I finally got the corrections made to my notes. The link above for the B3B wiring harness info now works.

I haven't detailed it out quite as much for the wiring under the dash because the information from Allan and David were for the B1B & B2B trucks so I left the wires a little long and figured they will have to have the ends put on them once the harness is installed. The change in the gauge arrangement on the B3B necessitated this approach.

What I will probably do sometime down the road is document further what lengths the wires were under the dash and update my notes. However that won't happen for quite some time as I'm 1800 miles from my truck and before I work on it again I'll have to move it from Arkansas to Kentucky.

If you're a B1 or B2 owner Allan's information is by far and away the best to use for making your own harness. The information I posted on making a B3 harness was based off of Allan's work and has yet to be proven to be accurate since I haven't completed nor have I fit the harness yet.

You can check out Allan's info here http://www430.pair.com/p15d24/mopar_forum/showthread.php?t=10669
