Was doing some wireing research about an Eleminator underdash main harness and found a reference to a connection for the Boss 302. I was under the impression that the only wire difference was a rev limiter, and I thought that it was a seperate harness. The diagram only shows several leads and does not show what they connect to. Can anybody enlighten me? Is there any difference from an XR-7, Eleminator or Boss302 dash harness?
