*IMPORTANT INFINITY 508 INFORMATION
The primary difference between the
30-7106 Infinity 506
and
30-7108 Infinity 508
is that the 508 lacks
Peak & Hold injector drivers to run low impedance fuel injectors. High impedance (saturated, high-z) fuel
injectors must be used with the Infinity 508.
The Infinity 506 and Infinity 508 share a common pinout with the exception of four pins where the Infinity
508 has two each additional fuel injector and ignition coil drivers. Due to the additional fuel injector and
ignition coil drivers, the 508 has two fewer digital inputs and lowside outputs. Use of this harness with an
Infinity 508 will require slight modification and will result in loss of some plug and play function- OEM
Coolant Gauge, Malfunction Indicator Light, and Brake Switch input.
