I'm putting a 3RZ out of a 98 taco into my 90 Toyota 4runner that had a 3.0 and 5 speed. I was looking into the off road solutions 3RZ swap harness and I want to know if anybody has used their harness? What you think?
I want to keep as much plug and play as possible althought I know it will require some splicing but how easy/hard is their harness to put in? I have everything else for the swap figured out just the wiring portion left
Thanks

Why didn't you go with a 3.4?
I'm sure you can make your own harness, just need the wiring diagrams for both vehicles.

Just looked on their web site. That's a lot of money. Does the engine you have now have the stock 3rz harness still on it?

3rz is gonna require more work than the 3.4.

Great writeup on marlin crawler website.

I know the 3.4 is easier but around here a good used runner is $1000-$1500 and I worked a deal with my buddy for this 3RZ and all the trimmins I want/need for $200 and I know it runs.
I know it will require more work but that doesn't bother me. And running a W56 with duals is better than the R150 with a chain drive EWW..
Anyway I loved my 22RE I had in another rig. Torquey little thing and I'm not after being able to burnout with 54s I just want something with reliability and good mileage and easy to work on.
I understand its not a power house but if my stock 22RE was great for what I do then the added power of the 3RZ should be slightly better which is just a plus for me. So just to shave down some time I wanted to run the ORS harness since it seems super simple and quicker just wanted input from people that have ran it.

When I done my 3.4 swap I was thinking about buying a harness from a company but what got me is you still have to do wiring to make it work. If you have both wiring diagrams, take about a week and make your own, unless you have money to burn
