Jeep WJ Remote Start Kit
A fully plug-and-play remote start solution for the 1999–2004 Jeep Grand Cherokee (WJ). Uses the factory key fob frequency and integrates cleanly with the OEM security system — no alarm chirps, no valet mode nonsense.
What’s included
- Custom PCB with relay board (4-relay configuration)
- Pre-terminated harness with OEM-style connectors
- 3D-printed enclosure for under-dash mounting
- Wiring diagram PDF (vehicle-specific)
- Installation guide
Wiring overview
The kit taps into three locations:
- Ignition harness (under dash, driver’s side)
- Security/SKIM module (column area)
- Starter relay (PDC under hood — no interior cutting needed)
All connections use T-tap or included OEM-style inline connectors. The unit is powered directly from the PDC with a dedicated 15A fused circuit.
