relays

[Baz]

is there a wiper motor relay and a headlight switch relay on the 77 Spider, ??
If so, where am I likely to find them....

There is no relay for the headlights, although it's a common aftermarket addition. In stock form, power for the headlights comes from the ignition switch, to the outer lighting switch on the dash, then to the high/low beam stalk switch on the steering column, then to fuses 3, 4, 5, and 6. Fuses 3 and 4 are high beams (left and right respectively) while Fuses 5 and 6 are low beams (left and right respectively).

The wiper motor does not have a relay, but there is the "wiper intermittent cycling unit", a relay of sorts, located behind the instrument cluster in the dash. Up against the firewall. Its function is to cycle the wipers on and off periodically, and it's frequently problematic given its age.
