Restore factory-reliable electrics with the genuine Royal Enfield 1040422/B Main Wiring Harness. This is the complete chassis loom that links ignition, switches, lamps, indicators, horn, charging and sensors on UCE-era Classic 350 and Bullet 350. Being OEM, it matches OE connector blocks, wire colours, lengths, fuse links, grounds and sheath routing, so it drops straight into the frame without cutting, splicing or chasing intermittent faults caused by aftermarket looms.

Fit this harness when repairing crash/rodent damage, fixing previous wiring “jugaad,” or reverting a modified bike to stock. Identity and application are verified across trusted parts databases and dealer listings:

FAQs

Q1. Will this fit my Classic 350 Reborn (J-Series)?
No. J-Series uses a different loom family. This part is for UCE Classic/Bullet only.

Q2. Does it include the tail-lamp or meter sub-harness?
It’s the main chassis harness. Sub-harnesses may be separate depending on variant—send VIN to verify.

Q3. My bike is BS3—will 1040422/B work?
Yes for the UCE Classic/Bullet trims listed above (BS3/BS4), per dealer fitment. Check Part Number.

Q4. Any installation tips?
Disconnect battery, photograph old routing, move one connector at a time, and protect frame grommets. Verify earth points are clean and tight.
