Need to replace all wiring in MF 202

Recommendations for replacing the 57 years wires on my new 2 me MF 202 Work Bull. I've got to split the tractor to replace the clutch and a major leak from the tranny. While I've got it apart I need to fix a power steering leak. So what the hey! I might as well replace all the wiring as well.

Should I:

Get a wiring harness for $??? from ???

Just try to match the color codes in the owners manual (why it's not in the service manual escapes me) with 20 gauge wires from ??

Wait for advice from the gurus at Yesterdays tractors?

Assistance requested please?
 
If it were me, and I've done plenty of automotive wiring, I'd be getting appropriately sized/colored wire, crimp/solder on lugs/spades/ring terminals, heat shrink and split loom tubing (or similar wire protection) and go to town on it. The 50+ year old wiring is probably overdue for a refresh. Not sure what's available for wiring kits, haven't ever looked for them but when I was working on a friend's '55 Chevy, he had bought a harness which was good for all the bone stock basics but if you want to add anything not originally designed for your tractor like extra lighting, alternator, digital tach, warning lights etc. etc. then you'll be cutting/splicing into your new harness anyway. Probably cheaper, as long as you have the tools, to build your own custom harness.
Just my $0.02, which in Canada would be rounded down to $0.00 'cause we got rid of all our pennies..........so take it for what it's worth
:lol:
 
The job is not to bad, hardest part is under the dash. My 202 is my work tractor so I did not worry
about colour codes I did use 18 ga wire and soldered my ends on. take some pictures for referance
the wireing diagram is pretty clear. I also changed my battery cables at the same time. good luck

Use the wiring diagram in the manual as a guide. Since all, almost all, the wires are striped i wouldn't worry about exact color matches. The gauge of the wire is far more important in my opinion. You don't want to be putting in 20 gauge wire someplace that needs 10 gauge, for example.
A little trick i have done in the past is take some romex wire covering and write on it what the circuit is. Slide it over the wire and use wire ties to hold it in place. Easy to pick out what wire does what in a bundle of all red wires.
 
I just get a few rolls of automotive 16 gauge wire with different colored insulation. With 16 gauge wire it will handle just about any circuit with no problems, plus (for me anyways) its easier to work with than thinner gauge wire.
 

Thanks for the tips all! I'll just get the right gauge wire for each circuit and label the tar out of it. Put in the split loom as recommended go to town. Should be a fun but easy project as I'm not adding any circuits to the stock 202
