Sources for aftermarket electrical components
I want to add driving lights and some other electrical equipment to my car. Modern electrical/electronic systems can be upset easily, so I tried to find an interface to which I could add a separate fuse block in order to protect the stock system. From NAPA I got a Balkamp part #782-5339. On the part is a label with: COOPER BUSSMANN Customer P/N 87315250 Bussmann P/N: 377031AN0022H R42. A mechanic told me it is the ideal part except for one thing: NAPA doesn’t have a plug to fit it to finish the connection(s). Can you help me either with this part, or another way to safely add electrical equipment to my Buick?
Adding a plethora of high-powered, high-draw aftermarket electrical components to newer cars is very commonly done and auxiliary fuse boxes are readily available. I am not familiar with the fuse box you bought from NAPA and using the various numbers you provided didn’t reveal any information.
Most aftermarket parts sellers who cater to street rods, hot rods, customs of every ilk, recreational vehicles, and kit cars sell fuse boxes, connectors, and everything else that you need.
It’s a good idea to utilize a relay wired through the ignition switch to route power to the secondary fuse panel so that the panel is not powered when the car is turned off. Painless Performance Products (painlesswiring.com) and American Autowire (americanautowire.com) are two of the many companies that can sell youwhat you need.
