Seppi72 Posted yesterday at 09:18 PM Share Posted yesterday at 09:18 PM There doesn't seem to be an electrical forum on HybridZ so I thought I'd put this in the model-specific one. I am in the process of adding several updated accessories to my original-owner S30. In particular: power windows, Vintage Air A/C system and RetroSound Motor 4 radio with quad speakers. I've already installed Dave Irwin's headlight relay system to take that load off the combo switch. I have a rebuilt 280ZX alternator from MSA to supply power once the Optima red top kicks things off. With all these new accessories, it occurs to me that perhaps I don't want to be chopping into the existing dash harness wires to provide them with power. So I'm thinking about installing positive and negative busbars on the interior firewall that I can hook up to as needed. Is this a wise idea? Has anyone ever done this mod and, if so, what parts did you use and where did you locate them? Quote Link to comment Share on other sites More sharing options...
jhm Posted yesterday at 11:11 PM Share Posted yesterday at 11:11 PM It can be confusing when talking about technical areas vs car model areas, but we do have the "Ignition and Electrical" sub-forum here: https://forums.hybridz.org/forum/16-ignition-and-electrical/. Yes, I think it's fairly common to add new circuits/etc to these old cars. I've done it to the last couple of my cars to simplify/improve the electrical capabilities over the stock harness. I've always used off-the-shelf breakers, relays, fuse panels, switches; but there are a bunch of pre-built kits that are available through numerous vendors. I like to use marine hardware if I can find it; as it's typically extra beefy and durable. Good luck with it; and please be sure to post your results once completed!! 1 Quote Link to comment Share on other sites More sharing options...
NewZed Posted yesterday at 11:13 PM Share Posted yesterday at 11:13 PM It's not uncommon. I added a terminal post near the battery for a few things. If I had a bunch I'd probably just install an auxiliary fuse box. Otherwise you have a bunch of inline fuses to take care of. There are many out there but a trip to the salvage yard would probably find one that is weatherproof and high quality. Depends on where you want it mounted. Looks like I'm on the same page as jhm, who replied as I was writing. 1 Quote Link to comment Share on other sites More sharing options...
