In order to sort all the cobbled, spliced, and who knows what else, wireing in my car, I need to find a brand new, complete wireing harness from the headlights to the tail lights. I hesitate to go with aftermarket, but that seems like the simplest and most cost effective way to go. It needs to be a just drop in and go kinda thing, Im not really good with wireing, and dont really have the time to piece it together and do it myself. Im thinking about selling my dakota and making the duster a daily driver again, but I want the peace of mind that its not going to catch on fire (been carrying around a fire extinguisher) :shock: even though nothings happend (thank god) yet

ezwire has a universal kit that's fairly decent. Painless Wiring is decent but uses undersized wiring gauges. Ez2wire is cheap, and looks it. Personally, I'd go with the ezwire kit. As for me, I made my own out of quality components, but I have an electronics background so it really wasn't that big a deal.

There's nothing such as a complete front-to-back "drop in and go" new OE-type wiring harness for an A-body. Painless is not at all OE-type, and is overpriced especially given the undersized wire and poor quality components. New OE-type wiring harnesses can be had; you will pay a lot of money for them.

My suggestion: find another car with good wiring and transfer it.

Year one carries all 3 harnesses Engine/Body/Trunk for the 1974 A-body.
Someone else makes them, I've seen people in shows who have used them and they look good, not sure about fit or function...$1600 or so for a complete harness isn't cheap and the engine harness will be for a small block...

Yep, I like Bill Evans' work quite a lot. The new engine harness for my '73 just arrived not long ago, and as usual it's really nice. But he doesn't do front-to-back harness assemblies, doesn't do underdash harnesses, etc.

While restoring a number of the Tidewater Mopar Club's giveaway cars over the years, I looked in detail into some universal harnesses. Those I looked at was more-or-less meant for GM's and GM-type components - adapting them to work with stock Mopar components (like the 3sp wipers, stock instrument cluster, etc.) was clearly far, far more work than just repairing the stock harness in every case. Unless you plan to put a GM column, switches, wipers, etc. into your Mopar I'd avoid the universal kits.

Mopars shared many connectors over the years between years and models. I removed the whole stock harness, laid it out, and very carefully repaired and tested it following the factory service manual, documenting any changes I need to make. A big collection of salvaged Mopar donor harnesses proved invaluable. I got replacement pins from NAPA, but took the plastic housings from the donors.

Generally, among nonstandard connections, only the bulkhead, headlight switch, defroster fan, and alternator output connectors were often damaged.

I'd estimate that 1/2 the damage was due to previous misguided repair and modification efforts. A lot of people think they know more than they do, especially when it comes to wiring. I would consider getting an underhood reproduction if there's extensive damage there; they're not expensive.

Repairing and testing the whole harness usually took me most of 2 weekends. If you have someone do it for you, be sure they do everything as good as or better than factory; any quick & dirty short cuts will come back to haunt you.

Just to rehash some wiring stuff mentioned elsewhere on this site: use solder for electronic components and not acid core, solder every connector or terminal or splice, use quality wiring, and fusible links are your friend.

I did mine as described above: took an old harness, laid it out on the back porch, and did a wire-by-wire redo. Yes, it's tedious. Yes, it's all done as mentioned above. And yes, any wiring you do will cost much more than you think it should!

I have replaced sections of mine, engine harness etc.... Yes, it is time consuming but all the connectors are available and you can actually upgrade the wiring gages and solider the ends/connectors so it is better than stock.

It is a piece of mind... :D

Just do one section at a time.

Not very happy customer on this deal with Evans harness for my 66 wagon.

Told him to make it up for EC and he tied the plug in about 4 inches out of the harness and I told him that's no good as there's no place to install the control box.

He said what do you want me do about it?

Well if the wires to the dist. are 18 inches long why not make the EC plug setup that long or ask how long do you need or want??

I had to ship back at my expense and he then stuck abill in it for more money for his mistake he's suppose tobe the "wire Guru".

Then I look on year 1 website and could have bought it for $80 less and this was a complete new harness as Evans just rewraped my lights wiring and the engine wiring is all new(sent him my old harness as a pattern) and I will check all crimped connections before install.

Also you better check all his crimps as I have found some not so good on my other harnesses and soldered them up after reading on the other Mopar sites.

I have bought from him before 3 different cars but, this is the last time.

Not happy at all with this deal and just my .02

Thanks,
Bill

I didnt think that a replacement harness would be easy to find, or cheap. I wish I could repair mine, but if you guys seen it, you would be scared too.. Its just way to far gone, bulkhead connectors are missing/broken/ or melted, as is most of the rest of the wireing. Too bad mopars are few and far between around here, or Id look for a decent origional one. My grandfather has painless in his streetrod, but its used only a few times a year, not for a daily driver. Ive seen universal mopar kits that are avail, but I dont recall who. Mainly I just need the engine/under dash section. The trunk is still fine, so If anyone has an origional set..
