that $7.48 looks like my OEM one but 10% of the price. to avoid going thru the firewall with the wire, which was a nightmare, I just came out the side of the hood, to the side of the window post and into the toad whenever I towed it. when not in use, just coiled it up under the hood. standard radio shack banana jack plugs would work just fine. IIRC my BB had 4 banana jacks, two for break away,two for activation sensor and they were color coded, don't remember "code" however.
