Please checkout the Xenocron "swap box" immobilizer delete in the ECU's & EMS's category.
This harness may require the user to pull the shock tower plugs into the interior for a better fit and cleaner installation. You are also required to drill a small hole in your exhaust tunnel for the O2 Sensor plug. After a year of R&D, this method is the way our customers doing this swap said were the best & cleanest.
There will be 5 wires to be connected to your factory ECU plugs with a diagram that accurately shows which wires to connect to.
You won't use your stock engine harness with the K20, but you still continue to use your chassis Interior harness with this conversion, so don't toss it or cut it!

Recoup of purchase price was worth it.
I was refunded the original purchase price of a HP Printer. Minus the cost of the insurance and packing I was only out half the original cost which in the long run is a win.

I have always purchased Asurion and they have always come through
Asurion really came through for me when I had an issue with my Canon printer. The process was smooth and easy from start to finish. The only small challenge was finding a box big enough to ship the printer, but once I had that, I just attached the label they sent and dropped it off at UPS.
They kept me updated by email every step of the way, and after inspecting the printer, they determined it couldn’t be fixed. The next day, I received a full reimbursement. Excellent communication and great service all around!

Great Experience!
I have never had to deal with Asurion before and was pleasantly surprised at how well the process went and at no additional cost to me. I shipped my printer on the 14th and it arrived back to me on the 21st, problem resolved. GREAT experience!

Good insurance to have
Asurion was great. After a few simple questions about what was going on with the unit, they issued a mailing label. Within 3 days of receiving the faulty unit they issued an Amazon gift card for the original purchase price.
