Run an ignition-on source from the primary fuse block under the dash to trigger the relay, run a suitable gauge 12v constant supply from the back of the starter terminated with a fusible link to the relay block, and then supply your independent auxiliary fuse block. My only complaint with the bussman 37702 is that the trigger wiring is intended to use a metri-pack connector which i was unable to purchase on an individual basis - online sources required a bulk buy of a dozen or more. I solved the problem with metri-pack sleeves without the plastic part. |
