hey guys, i have an ef xr6 manual harness n ecu, i am looking at buyin and ef classic,it has air bags not sure if it has abs will the xr6 ecu work??

If the car has ABS, then the XR loom is identical. (they're nothing special)

If you install an XR engine loom (Futura/Fairmont) into a non ABS equipped GLi, you'll then have to install the body loom as well for the rear abs sensors.

otherwise the EXU will work EF to EF and EL to EL ONLY
