simple question i hope - but I've got a buddy with an 01 xterra that's throwing three O2 sensor codes for no activity (po134/140/154). Seems like this is an option, in addition to cleaning all other grounds. so: when installing this harness, do you simply secure one pair of eyelets under the existing ECCS harness and the other to the lower engine mounts? maybe a dumb question... my apologies. just trying to be sure that there's no modification to the existing ground contacts on the ECCS harness.
