How to Install a Train Horn on a Kia Soul
Train horn install for Kia Soul — boxy hatchback, generous cargo envelope, single or compact dual-trumpet, OEM horn fuse-tap, ICE and EV variant fitment.
The Kia Soul is a boxy compact hatchback with a notably generous cargo envelope for its segment — practical install platform compared to a Mini or Miata. A 2-gallon Conductor’s Special 228H fits comfortably in the cargo floor, with trumpets routed to the front bumper area. Same general install pattern as the Honda Civic but with more room.

Soul-specific install considerations
- Generous cargo envelope — boxy design gives more vertical space than typical compacts
- Soul EV (PS gen and SK3 gen) requires Tesla-style approach — 12V auxiliary battery only, never HV pack
- PS (2014–2019), SK3 (2020–2024), and SK3a (2025+) chassis are different — verify fuse-box layout
- OEM horn fuse layout uses standard MICRO2 add-a-circuit pattern
Recommended kits
- HornBlasters Conductor’s Special 228H — fits Soul cargo floor.
- HornBlasters Outlaw 127H — single trumpet alternative.
Step-by-step
Same procedure as the Civic install guide — cargo-floor mount compressor + tank, route airline forward, MICRO2 fuse-tap to OEM horn signal.
Common Soul-specific problems
- Generation differences between PS / SK3 / SK3a affect fuse-box layout.
- Soul EV vs ICE Soul — different power tap procedure.
- Standard MICRO2 fuse-tap issues as documented across vehicle install pages.
Legal reminder
Same as any aftermarket train horn. See /legal/.
