i've been pouring over the "murp****s" document for installation of audiovox CCS100 installed ina '91 concours. in the doc it's mentioned that a 20ohm 1watt resistor is supplyed with the controler. the resistor is used as a noise supperssor , installed on the blue lead from the coil. a quick glance at my own reviels there's no resistor. did audiovox do away with this idem? if i go out and buy/install this idem, does it improve the installation?
