Main and accessory relays are located under large metal bracket in rear of relay compartment, main closest to the front. Main relay is your biggest concern (car will run without accessories). I believe they are identical (double check me on that John Hervey), so you can simply swap to diagnose relay only. To double check switch, just jump relay triggers with their own brown power lines. That's all the key switch does (go ahead and use a fused jumper, though you'll note key switch isn't fused! Trigger wires are supposed to have diodes, but unplug anyway. Will make it easier to jump if nothing else). You really only need key switch to unlock steering wheel -- rest of car can just about be operated behind passenger seat. Bill Robertson #5939
