I have a relay which needs to be plugged back into a black two rung terminal strip located behind the glove compartment. I pulled it without noticing where it was located. Can someone provide me with a diagram to locate that relay. The terminal strip is black and has two relays plugged into it (one being the horn relay). I assume the relay plugs somewhere into that terminal strip. Would appreciate some help.
Thanks

Re: Need to locate Relay
Below are what my Chilton’s manual shows for 88-90 Bonnevilles. You’re definitely going to have the horn & fuel pump relay. 3rd one may depend on your options.
