93 240 Classic Wagon
Trying to find the main headlight relay as Dave Barton calls it;

"""2. Main Headlight Relay, This relay exists in the 1986-93 240 only, Volvo PN 1324749 (or 1235013) (click here to find it), or Bosch PN 0332015001, 0332015006, 0332015011, 0332015012, 0332015016. This relay is a mystery to many 240 owners, because it's tucked away out of sight under the dash. In the '86-'87 240, it should be found behind the clutch or brake pedal area (see relay diagrams above). For the '88 or '89 to '93 240 (exact year of this change is not certain to me), it should be behind the center dash area, just below the accessory gauge locations (or radio if yours is up high). This relay fails far less often than the above step relay.
FAILURE SYMPTOMS: Headlights might turn off on their own after a short time (and your fuses are good). Headlights may come back on after switching them off, then on again. Or you might need to wait a while and try again (after they "cool off"). Or headlights may not come on at all when the switch is turned, but your high beams will flash normally when the flasher stalk is pulled back."""

I have a good portion of the dash out and have found many hidden relays including one that by search only shows a thread entry where someone tried to find it but that Tasca showed it as no longer available. Other than that, it seems to be a common topic on Russian Volvo forums (which btw is Volvo 3 545 619).
That is beside the point. WHERE the H is the mani headlight relay that he talks of??
