I have several accessories I’d like to install. I’d like to have a 12V power bus located in my dash to feed them. See attached drawing.

I haven’t seen anything that quite fits (Relay + Power bus + Ground bus - all in one.) While I could probably build something, I’d rather not re-invent the wheel. Is there something out there?

Suggestions?

Yeah... It's called a Power Distribution Block. Simply replace your indicated "bus bar" with it. For the relay, you can use either the Bosch 30A, 5-tab, or you could use something a bit heavier, like a 200A starter solenoid.

ANY car stero store around you will be able to provide you with a adequate distribution block. It'll also allow you to fuse each output, for safety.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

About midway of the following page are 2 Constant duty solenoids that will do what you need. The PAC-80 is good for 80 amps and the PAC-200 is good for 200 amps. A starter solenoid is not a constant duty device. They start to smoke after about 30 seconds of use. If the 80 amp unit will work for you, It is available at NAPA auto parts stores as a Standard Ignition S-55

Yup, thats what I'm looking for. I can't find a "Standard Ignition S-55 " on Napa's website. By chance, do you have the part #?

Thanks.

They may or may not still sell it. 20 years ago they did though. Call them they may not have every item listed on the website. The search function on their page is USELESS.
