6cyl avalon 1999
plugged harness in and car fired right up
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
- Stock Engine Harness
- Coolant Temp Sensor - keep in stock location
- MAF - Can cut air box lid off, but best to run cone filter on it to fix air flow issues
- All other stock wiring gets disconnected (fender wiring, dash wiring, fuse boxes, etc).
* Pinout info for accessories can be found on the derby specs page.
Immo Identification
- 3 Coil - Center connector missing for no immo
We can flash your computer to immo off or you can use a modded/tuned computer. A DIY work around would be to source a comptuer from the same model of car that is factory immo off.
Fitment:
- 1998-1999 Toyota Avalon*
* 1998 had two computer options, make sure your connector looks like the one on this page with 3 rows of pins.
