Have YOU rewired your Charger yet?

[Kern Dog]

My beloved 70 Charger is technically 43 1/2 years old since it was built in December 1969. It started out as a 318 car and has seen many changes since it was first built. The wiring, however, is almost totally original. I did add a MP electronic ignition kit when I swapped in the first 440 in 2002, but aside from that, everything else is original.
I know that the headlights could be brighter, but I have had no other problems with the electrical system. The ammeter is still stock since I have yet to have the guages restored. I have a friend that is willing to rewire the engine side of the harness. He did this with his 71 Road Runner. He added relays for many components and his headlights are nearly as bright as newer cars. I'm tempted to move forward with this, but one concern is trying to maintain a factory-like appearance. I'm interested in reading from those of you that have made the move.
Thanks, Greg

With my last Charger-it had so many problems and the wires had been spliced so many times it was ridiculous...that when I got the whole thing rewired, no more headaches, no more gremlins or weird stuff happening. Lights were all MUCH brighter and I wish I had done it sooner!

Here to keep it original buy from here, they even have an engine harness to suit electronic ignition.

Pieces of it. The radio harness, the tail lamp harness is from an 87 Daytona, some of the engine wiring is uhhhh, "custom" shall we say...

Hahaha custom pieces here too, lets say the engine and cabin wiring was ''unorthodox'' and had to fix 30 years of hack jobs to make it safe and reliable. So, I had to make make own looms, not too much of a prob since I'm a sparkie anyway just time and a grind of a job , but, in hindsight I would opt for the Evans loom sets

Hey Red, I was going to do the relay mod for the headlights myself but instead am going with b5blue's solution.  My wiring has never been hacked so I see no reason to replace it.

While everything worked when I got my Charger way back in 1976, there was a "mysterious" wire or two on it. When we started the restoration i planned to get all new wiring harnesses for it and I did.

I rewired my car 5 years ago during the restoration, i used M&H wiring. Best money i ever spent on the restore.

Since I'm about getting started on my 69's resto., I'm also wanting to replace the whole wiring harness. Since the wiring is over 40 years old, I'm not inclined to depend on the original wires to do the job anymore and don't want to be chasing shorts in the system so out with the old and in with the new.

Good plan!!

If you're worried about factory appearance, hide the new headlight relays under the battery box.

When we bought our project 2 years ago it ran but only started with a toggle switch and there were no lights to even see if they worked.   We knew we would switch the wiring at some point, so we bit the bullet first and bought a complete wiring harness from year one.  Once we pulled out the old there were so many breaks and corroded bare wires we were lucky it wasn't hooked up!  What a great feeling to turn the key and have the car start and stop!!   Ran all the new harnesses and it will be great to Put it back together next month!  I would highly recommend the new harness, plug and play!

I picked up a 21 circut complete front to rear harness for my 72 for $160 from ezwiring.com havent put it in but it comes with prewired headlight relays, horn and blinkers. everything color coded and even says what it goes to on the wires every few inches. i doubt you can beat it for the price however for an oe type deal it uses the mini fuses so it wouldnt be a good choice however they do have kits with the standard bus fuses with less circuts

[tan top]

  used all M&H harnesses going back after the resto ,  then went back inside the dash harness to do my own take on the madd amp gauge by pass 5 years later  , then proceded to get carried away & redesigned the charging circut & power supply to the fuse box , headlamp & ignition switch &  protected every thing with blade fuses , over kill yes !! but once started just escalated

  My wiring has never been hacked so I see no reason to replace it.

IF my wiring is all original in everything works perfectly, is there any reason why I would still want to buy an all new wiring harness when I restore my car (safety concerns I should still have?). 

[Kern Dog]

I see the point. If it works, why mess with it?
I know very little about electrical systems, but it seems that when things go bad, it can happen quickly without warning. I had a 76 Camaro in 1994 that once started cranking over even though I was 20 feet away! The starter leads had come cracks in the insulation and arced to the block. It didn't start, but it was creepy. The Charger is worth 10 of those Camaros, so the money spent on a rewire is cheap insurance. A fire to the car because of aged wiring is an avoidable thing.

[Darkman]

There was evidence of an electrical fire in my Charger. Most of the wiring under the dash was hacked into and spliced in a very poor manner.

Putting that aside, even if the splicing was done well, most of the wiring under the dash was brittle. There is no doubt that the wiring will be completely replaced. In my case, it will be custom made to run all the "gadgets" that are making up my rebuild.

THIS is impressive. I may just look into this option for my car. Thank you, Greg

[Rolling_Thunder]

Been there and done that...      on a LOT of people's cars...    I've used EZ wiring, Painless, Ron Francis, Evans, Isis, M&H....      

All depends on what you want to do...     I used painless because of cost, simplicity, and the fact that not much on my charger was going to be stock...        

As for the debate "if it aint broke don't fix it" -- electrical wire degrades over time as power is passed through it...  so over 40+ years it is always better to replace it with new   

[projectanimal]

Last summer we witnessed a bad electrical fire on a beautiful 69 charger as it was trying to pull into a car show..     I couldn't in good conscious take any pictures (as I felt so bad for the guy) but thankfully he pulled right over and they got the burn to stop before it toasted the whole car.   It looked like it started by the firewall block around the brake boost.   not sure what happened after the car show, but hopefully we will run into him this year!  we already had the wiring harness on our list, but this pushed it to the front of the line and we went with the nice plug and play.  we were going to use the Painless system, but all our connections were toast so swapping them over would have been useless. 
If you have the time and money to invest in good wiring I highly recommend it....

If I would see ANYTHING wrong with my wiring it would have been yanked out and replaced.  If you have doubts about the wiring in your car then by all means remove it.  I initially planned to rewire mine but when I found this car, the previous owner had taken real good care of the car and the wiring had never been touched, not even to install an aftermarket radio.

I'm hoping to drive this car for several more years until I am done with school and have a good paying job and free time.  First winter after that it'll get restored and I 'may' swap the wiring at that time but right now there's just no need for it.  I checked a lot of wires on my car and they are wrapped as they should, no splices, no burns, no hard insulation even.  At some point I thought someone must have replaced the wiring already but I can't find any proof of that.

I do check my wiring a lot, just to be on the safe side although even if you do replace everything, shit can still hit the fan and burn the car to the ground.

Honestly, I am much more worried about a gasoline fire than an electrical fire with these old beasts.

[Brightyellow69rtse]

i went with all new m&h harnesses and couldnt be happier with them. their customer service is the best ive ever had hands down!

[1970Moparmann]

In my book, wiring upgrade is a #1 thing that needs to be complete during a restoration.   

Look at the fire potential rats nest I have for my Bird I picked up a few months ago. 

[dodgey68]

yep same here, wireing had a real lot of issues, hacked, spliced, and hacked again, some fried, and since i was restoring the car, i got a complete new plug and play wire harness from year one, bloody brilliant and simple, reasonble price on kit, wasn't even  going to  try and repair the old one,  not taking that chance,,,,,,,
not to say the new one wouldn't give me any issues....
