Aftermarket wiring harness
#1
Pulled my wiring harness out of storage the other day and what a mess!
Not looking forward to having many wiring issues and the fact that the PO had extended the harness to suit RHD it hasn't been done well.
First contact was obviously Midlife who has been more than helpful however due to my harness being modified and RHD he suggested I might be better off going with an aftermarket harness.

My initial research comes up with 2 companies, one which should be renamed painful wiring which only sells a universal harness meaning I would have to splice nearly every wire to OEM connectors. The other company is American Autowire and although they have some better priced universal kits they also have a specific 1971-1973 Mustang update harness kit here - https://www.americanautowire.com/shop/cl...update-kit
Fairly expensive  at $999 so it would need to pretty good for that price

Anyway interested if anyone has experience or fitted an aftermarket harness to their Mustang especially the one mentioned above

Hi Oz, I used the Ron Francis access 24-7 ford kit. about 550.00 u.s, I'm happy with the quality and features. The movable easy access fuse box is a nice plus. however it was ALOT of work and time. My brother in law who is an elecriclal engineer was a huge help. Not many things on my car are of original type so this harness worked well for me. That said, If I were looking to do more of a factory replacement harness. The extra money for the specific harness may be well worth it.

Ouch!  I thought the aftermarket kits run about $4-$500.  With shipping back and forth, my work would be in that price range.

Thats a pretty nice complete wiring harness. I never knew they actually made one for our years. Lots of great features, but damn thats expensive.

Thanks Keiths71 and I did come across Ron's website today so will check it out

Jowens - you are correct about the price but at least you guys don't pay the shipping I do, does look like a good set up though and would be far better than wrestling with a universal type kit

Midlife, yes there are some harness kits in $480-600 range but would require a lot of work to get them to fit as Keith mentions

To be honest I'm not fussed if I use my original harness refurbished or aftermarket as long as either will work well and not give me too many hassles down the track
I will wait to see what feedback I get from AAW but if you reckon you can make mine good again and with shipping it comes well under $1k then I would still consider it
I do like the AAW set up so far with the later fusebox and upgrades for guages, alternator etc though but will need to have a decent win in the lotto to pay for it!

One other thing to consider with a universal kit is you will need a good soldering iron, solder, shrink wrap, a lot of tape, protective sleeves, clips, grommets etc. That stuff does add up. One of those harbor freight third hand things was handy. Also it's a good idea to add a fuse or circuit breaker which you have to buy separately

If price-wise it came down to an aftermarket or a refurbished Midlife harness, I would definitely go with Randy. It will be right, as close to OEM as possible & he will support it.
An added plus is that the factory wiring diagrams will still be usable (read left to right) and the color codes will be correct.
As a matter of fact, I think that once you factor in the time it will take to 'fit' an aftermarket harness Randy's is the better deal anyway.

It won't be OEM due to the car's conversion to RHD.  The prior owner added a section to the headlight harness to mate with the fuse box, now located on the RHS, a section added to keep the tail-light harness on the LHS, etc.  The sections that were added were cobbled together poorly.  The car has never run with the modified wiring, so I do not have confidence that the lengths added for these sections is correct or not; without access to the car, I can only use what the prior owner judged to be correct.

As far as electrically wiring things, I can do that, but the RHD conversion adds an awful lot of complications.  Take one example: the connector for the parking brake is located just inside the firewall grommet for the headlight harness.  I presume that needs to be re-located to the RHS.  Is that located on the left or right side of the driver himself (probably the left), but exactly where?  Similarly for the dimmer switch...

This would not be a straightforward refurbishment.  I need to avoid any returns due to the high shipping costs to Ozz-land.

Midlife is correct that as the harness I have has not been tested or done well it would be difficult to get it work well and the lengths right so short of flying Midlife over to sunny Western Australia I think he is correct in saying I would be better off with an aftermarket harness plus I will be able to add extra circuits easily.

I have heard back from AAW on the classic upgrade harness and they are not sure on using it for RHD yet although I thought since they mount the fuse box on the RH side behind the glove box for LHD then most of the harnesses should actually be longer but waiting on more info.

They actually suggested I use this universal style kit - https://www.americanautowire.com/shop/hi...wiring-kit
Less than half the price so may just go that way and spend a few frustrating days wiring it up

I have also asked for the benefit of any members considering the Classic Upgrade what is the advantage of this kit compared to a Universal style kit
At the price they sell for it would want to be good and easy to fit but I don't think it will be putting Midlife out of a job anytime soon
