Power Harness INT-5B + ECU-4A + ENG-13A

This harness is effectively a power adapter to convert your stock engine harness into a stand alone harness. All other stock wiring gets disconnected from the engine harness including the fuse boxes.

Requirements:

• Starter hotwired
• Fuel pump hotwired
• Ignition hotwired (Power Harness)
• No immo (I think all RX300's have immo, so a derby modded computer would be the best route)

Fitment:

• 2000-2003 Lexus RX300
