Best round fuse block upgrade????

[4x4 Station Wagon]

My 80 has round fuses and I am sick and tired of cleaning the contacts only to break the next one off.... I was going to go with two marine style 6 fuse blocks in order to have one acc and one 12+ all time hot.... But honestly looking at the current set up it would take three 4 pole fuse blocks and something for the headlights to do it right.... Thats a mess. So at this point I am thinking of soldering and heat shrinking in a newer toyota square fuse block. What year did they switch and more importantly is there a better way others have found? I searched and can't find squat

For the money, you won't find a nicer product than this one from busman BUSSMANN RTMR 15713-24-12-22A

And to answer your question more directly: it was around 1991 when Toyota significantly increased the reliability of their wiring harnesses.

So please help me understand the lingo. It says 1, 2 or 3 bus are available for split power so does that meen 3 different power sources in the one block? If so that is perfect

Yes, but you will find out that X position is only connectable to Y power bus.

I'm still not clear how many branch circuits that one supports.

And do they sell the 8-pole model?

The best I could figure is it has three main circuits which is from the title. As for how many branch circuits per main circuit, who knows. The total number of branch circuits is 24. Looks like two of the main circuits have 1/4" studs for hooking them to power, while the other one uses 1/4" faston connectors.. They give the full manufacturers part number so it should be possible to figure it out. The PDF I found didn't have the circuit layout. On the other hand it said output terminals not included, and gave a Delphi part number for them. pg# 12 in: http://www1.cooperbussmann.com/pdf/fdee239d-3e78-4df3-832f-fea4236a26bf.pdf

Thanks for the help but I said to heck with it and picked up a newer stock square fuse block. I do not have my paperwork with me but it had like 9 power feeds/circuits vs. 5 that the round fuse block had. I ended up combining a few circuits exactly as the round block had done. It should work good for me as I have not loaded any circuits harder than the stock 1980 had. I just climbed in the house from finishing it. I was able to figure out that part of my fight was a bad park light relay.
