Question
Where is the instrument panel relay located

Answer
Hello,

Car is to old for me to remember such details, but my first question is why are you looking for the relay? Relays almost never fail which means the points would have to stick open or closed.
Did you consult with your owner's manual?
If nothing is comping on in the dash, these did have problems with the instrument panels and dash connections as well as loose grounds under the dash. If just the dash lights are not working, make sure you have tail lights. You could also have a bad thermostat for dimming and brightening.

In that era I think I remember a separate factory service manual for component placement.
I apologize for not being able to give you the location of the dash light relay if there is one, but that was 26 years ago and thousands of vehicles and hundreds of makes and models ago. Any manuals I had for this vehicle I discarded over 15 years ago.
As stated though, if digital display, they were nothing but a headache since new in the 80s.

Diving into dash light problems can be expensive and very frustrating without a factory service manual you may find on EBay or Craig's.

Good luck!

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
