VG30 RB25 Ignition Chip (PTU) Bypass Harness.


This harness replaces your factory ignition chip (PTU) when upgrading to smart coils like R35, R8, LS, etc. This is a plug and play solution to save you time cutting, splicing and soldering. Your conversion would also be completely reversible.


-Suitable for VG30 (as well as DETT) and RB25 engine models.

-If you prefer different color wires (will come red by default), please make a note during checkout.

-Free shipping in the USA.


Note: When upgrading to "smart coils", it is necessary to adjust ignition dwell times through your ECU's interface to match the coil model that you are using.
