I have a TC33 that the rats ate the harness up in picture 1. The replacement harness I have is in picture 2. My problem is that my manual only shows the schematic for harness 1 and not 2. Can anyone identify which model picture 2 is off and where I can find the schematic? I would be grateful if anyone could share the schematic for harness 2. Thank you

I'm wondering if you have harness for a non-deluxe model, or if there is a difference
between the harness for a TC33 and a TC33D.

Refer to the attached PDF, the deluxe has a 20 amp fuse solely for the front lights, on the non-deluxe the front lights and rear flashers use the same 20 amp fuse?

I need a complete schematic of the loom #2. Loom number 2 might have a turn signal switch and has multiple other plugs that my tc33 does not. I want to make Loom 2 work. Loom 2 has all the same as Loom 1 but has additional plugs, and wiring is routed differently to different relays such as start, glow ect.

I have the manual for a TC29D and it covers TC33D. I'm not up on the terminology, so if you could explain better what you need, I will see if I can help.
Also, is it HST or gear? Yes, it makes a difference...

What does your fuse panel look like, is the fuse in the 3rd slot from the top a 20 amp or 7.5 amp?

It's difficult for me to tell from the pictures of the fuses, but my guess is the 3rd fuse from the top in both pictures is a 20 amp which would lend me to believe they are both deluxe version. The schematic which you posted is labeled as a deluxe.

Attached is a PDF of both the deluxe and economy TC series tractor's electrical schematics. I hope you are able to figure it out.
