Headlight relays, driving light relay connections, trail light connections, Weather Pak connectors, wiring sizes that don't dim out the head or tail lights, dedicated ground wires to get rid of all the wiring 'Issues' that is 90% of the complaints,
Places in the harness for electric fans...
Basically upgrading with the 40 years or so of technology that has passed since the last 'Revamp' of the CJ harness...
I'm thinking of having an 'Idiot Proof' add on,
You can run stock headlights,
Or you can upgrade to H4 and relays, depending on what you want to run...
Also got my hands on some water proof relays!
GM used them a BUNCH in Cadillacs and if it's good enough for a CAD then it's good enough for my Jeep!
An H4 headlight option, Trailer connection option, Fan option.
If you want to upgrade or add on later, the plugs/connectors will be an 'Off The Shelf' item and 'Plug & Play', no trying to figure out color codes, splice into wires, ect.
Simply unplug the harness, plug in the adapter, and you are off to the races!
MODULAR HARNESSES are always a good thing!
The ONLY thing I can't upgrade is the 'Bulkhead' connector without a full harness change,
And the dash connections.
The dash cluster and under dash wiring can be cleaned up a TON, but I'm stuck with the factory gauges, switches, lights, ect.
I CAN get a headlight switch/connector that actually works and uses the Jeep bezels that have 'Ignition', 'Lights' 'Wipers' and 'Hazard' bezels, I've figured that one out,
And the headlight switch would have to be changed,
But that's MINOR for someone that doesn't have to battle wiring in total!
Harness runs that DO NOT have exposed wires, everything is sealed up it's own water proof, rub proof casing would be a good thing to have, instead of a bunch of loose wires in a plastic sleeve that might, or might not be protecting anything after 25 or 35 years,
*IF* It's still there, and *IF* it's not cracked or melted...
I could probably go the 'Painless' route, build a harness that is just as inadiquate and generic as the AMC version,
But the upgraded technology is there, Why not use it?
