Relays, Timers, Control Units

Incorporated in the vehicle electrical circuits are several relays, some of which are located behind the lower dash panel attached to the steering column support bracket. Relays are also located in the engine compartment attached to the closure panel, these relays are accessible having removed the black protective cover. The remaining relays are located beneath both front seats.

The relays in the following images are identified in the chart at the bottom of the page.
