Re: Fire Damage Repair

Mike:

This is precisely the type of advice I was hoping for. I knew it was going
to be much more than replacing a few wires.

I have a complete harness, which arrived a couple days ago, and when I
opened the box, what I found looked like an Eagle's nest made of wire.

Nevertheless, this is a great, clean, solid Jeep and I will do whatever it
takes to restore it, even if I have to resort to taking the project to a
shop. The problem there is finding a good Jeep shop in this part of the
country (North Idaho).

Many thanks for the help.

Sincerely,

--

Re: Fire Damage Repair

Depending on the harness you got, there are a couple ways to install
it. If it was labeled then you can tear out all the old stuff and go
for it.

If it isn't labeled, then I prefer to either lay the new one beside the
old one which can be interesting for tangles or I cut the old one at
each plug leaving an inch or two of the old wire hanging there for a
color and gauge matchup. I then just swap the plugs as I install.
Depending on the condition of the 'new' harness' plugs, sometimes I just
leave the old plug in place and solder and heat shrink the wires onto it
for the better conditioned plug.

Do yourself a favor and get a bulk supply of zip ties. Securely reattaching
the wires helps prevent a round of new electrical problems several years
from now after the wires have bounced around, wore out or worked loose.
Also remember not all connectors have a place to connect. Quite often a
harness has applicabilty across several models and years. Some may have
more connections than you have equipment for.

It also helps to take copious notes on what connected to where and if the
colors were different on both sides of the connector. I've had plenty of
situations over the years where the plug had wires of one set of colors on
the plug but another set on the socket. Never had to do much Jeep wiring so
I don't know if that's a likely problem or not. But if you've got an
in-line connector (not going direct into a socket on something) it really
helps to make note of the colors. Assuming, of course, that the
replacement harness follows factory colors, that is.

I've generally found a vehicle that's caught fire is not one worth keeping.
Fuel fires being least problematic but electrical ones the worst. If there
was something 'wrong enough' about the wiring that the designed system
couldn't handle via fuses I'm never confident it's going to get solved
without truly pinning down the problem. So if you're not absolutely sure
where the problems are you'll probably regret trying to keep it. But hey,
give it a shot!
