The HO2S relay is not part of the relay panel anyway, though it clips to
it externally. The Power relay and FP relays can be just standard relays
like all the waterboxers have in a separate relay box in the engine
compartment for those 2 functions. Far cleaner and simpler to use one of
those or duplicate it with a similar setup than to use the entire
vehicle relay panel from the engine donor. You only need 2 relays and a
fuse. The donor panel has provisions for 12 relays and 22 fuses, not
counting the external ones clipped to it.

Any externally mounted relay socket from the donor with a 53 or 24 relay
in it can be adapted for both FP and Power uses.
