Sorry for all these questions, if I cut of the cigarette adapter for both SGZC12RC and SG9665GC but keep the in-line square box for SG9665GC can I hardwire to the Vico-Power Plus or will having two cams strain the Vico?For the SG9665GC as long as you leave the in-line square box in place yes. (That's what does the 12V to 5V conversion). My last reply is for the SGZC12RC only.
You mentioned that the cams are about 1Amp each and vico has a max of 2Amps.
