Hi , what problem are you having ? There is no such relay on a 89 Cadillac ! Could you possibly mean a ASD relay - auto shut down relay ? That component is used on Chrysler products !

did you use the correct type of Freon for the compressor type?

You could get a buddy to turn the key to the on and off position a few times while you hold the valve stem on the fuel rail on top of the motor to get the air out of the lines. It probably has a air lock int lines

here you go hope it helps Tim:

any car can fit 4.5. by modification, even srt10 8.3L can be we did it at mazda 82

Security system is active, look in your owners manual to deactivate

check to see if you have spark it could probably be that you have either a crank sensor issue or that the cap or rotor is bad

Sounds like the battery is weak or the alternator isn't providing enough amps to keep the engine running and power the lights at the same time.
