'98 grand prix gtp/oem stereo p/n 16228082/after market pioneer deh3200ub. replacining oem pontiac stereo with after market stereo don't want to cut or splice into oem connectors. is there a jumper adapter to do this, already have the converter so steering wheel controls will work w/deck. if not where can i get connector ends to make my own?
