Modifying Fuel Cut-Off Relay

    NOTE: Part of relay skirt may be cut away to provide easier access to pins.
  2. Solder a 16-18 gauge jumper wire between pins 2 and 4. Feed one end of an 8-10 ft. flexible wire through hole drilled in relay skirt and solder to pin No. 1. See Fig 1 .
    NOTE: Leads should be soldered as close to relay base as possible to permit insertion of relay into socket with minimum interference.
  3. Solder an alligator clip to other end of 8-10 ft. flexible wire.
