BTW for what its worth....I still stand behind my love for the painless harness.....Mine didnt have one piece of oem wiring in it so that may have made it easier since I didnt have to be concerned with matching up anything......(did have to wire in the turn signal harness but that was too easy)..........
 
Just snapped a quick picture of the current status of my fuse block... I cut a few wires short, its on my list of things to finish after I get the transmission and tcase back in this weekend.

Since we are doing show and tell ... here is my Centex harness all terminated and bundled on the living room floor. It's mated to Autometer gauges, a 3FE computer, and FJ62 steering column using the FJ62 wipers, lights, flasher, and horn switches. Missing from the pic is the "tail light" harness, the "tranny harness" (speedo, VSS, 4x4 switch, reverse switch), and the main engine harness. I have 7 wires left unused, though one will be used for the CB radio. I still think the 10 circuit GV10 would have been the ticket. At least I have a few to grow into. Connectors are GM Weatherpack.

It's six of one, half a dozen of the other. I personally like the Painless 18 circuit one as I have rewired with it before and it gives me plenty of extra fuses as I need them.

Compared to the alternative of having to put a fuse block, wire(usually one color and not labeled), and fuses together on your own like it was back in the day, all of these products are painless.
 
I highly recommend this kit after installing one in my landcruiser.... You don't have to deal with extra wires off the fuse block.

I still need to take some pictures of it finished.... I still have several open circuits on the fuse block.

That old link is bad..
It can be found here now:

Highway 15 Modular Panel System Wiring Harness

There is also a "Highway 22" version, which is probably the same, but also can accomodate a second battery, I believe.
 
I have purchased a wiring harness from JTO. It's a Kwikwire 14 circuit, blade fuses. I havn't installed it, I need some motivation:beer:

This harness looks to be really nice. I am thinking of doing a complete rewire also but I wonder if I should make sure to ave my old harness around the connectors or does this harness have all the correct ones to connect up the FJ? I also will have a harness for a TBI 350 that I have dropped in, do you think this will be compatible? I suppose I could just call American auto wire, but prefer to ask someone who has installed it on an FJ.


Thanks for helping

For future readers contemplating harnesses, I bought one from Coolerman and am 100% satisfied, plus, it is OEM.

I just finished putting the Painless harness in my 71 FJ40. I was lucky and had the help of an Electrical Engineer/Techno Geek who also teaches an automotive electrical class and has an FJ40. Without that type of experienced, knowledgeable resource, and knowing what I now know about what is involved, I would recommend that you buy one from Coolerman or be prepared to be frustrated, confused, and to spend a great deal of time with the harness spread out on your dining room table or some other such large work surface (hope the Princess understands). Unfortunately, Coolerman has temporarily suspended operations as he moves his residence and shop. That may or may not fit your schedule needs.

You should be aware that the various wiring diagrams for different years all have errors or represent features and options that may be in your truck, but are not accurately reflected in the diagram for your particular vintage. My guess is that Toyota added advanced features to the USA trucks but left them off the wiring diagrams until production volumes for that revised system increased and updates were made for the later vintage FSMs. I found features in my 71 truck and wiring harness that were not in the 71-72 diagrams, but showed up in the later diagrams, sometimes with slightly different color codes and routing (driver vs passenger side alternators, etc.).

Another difficult aspect of the wiring harness task, and one that is not frequently mentioned, is getting it loomed properly so that the proportions are correct and everything fits without strain and with some semblance of order. It requires a great deal of careful measuring, and no small amount of trial and error. Another consideration is that Coolerman already has that part figured out.

I ended up creating my own color coded wiring diagrams so I have a reference of what I did. I strongly recommend that anyone building their own harness from a kit do the same. Even if you rebuild a stock harness wire-by-wire, note the revised color schema on the FSM diagram whenever it has to be changed because duplicating the factory color coding is cost prohibitive if you are only building a couple of harnesses.

Good Luck!
 
Well, I have to admit I'm a little freaked out about doing a complete overhaul on my wiring, but after digging into it, it was a complete rats nest. Anyhow, wish me lots of luck in this adventure.

just realize that it takes time

and look at the many rewiring threads here on MUD - practically every issue has been convered

X2 on making a diagram of your wiring as you go along, so that you can troubleshoot later
