We know that changing the supercharger and necessary components is do able for most but when it comes to cutting and splicing into your factory harness sometimes it can be a bit overwhelming. We @ DRS offer a service that we will convert your harness for you for the nominal price of $150 plus shipping. This involves professional installation of the Splice, Stock ECU Reconnect, Intercept tails as well as converting the injectors over to Bosch style from the stock Denso style. Turn around time is aprox. 1-2 days. If you have any questions please feel free to PM or call the shop @ (562)694-2226. This offer is good for all 05'-09' harnesses.
