Re: What are these 87 trans am

gt4373 is right about rear defogger relay,the Yellow Buffer is a vehicle speed sensor.is there a P/N on the white relay?

Re: What are these 87 trans am

I'm almost certain the ECM is involved with the speed sensor. The headlight relays are under the hood.That relay could be the hatch release,Horn relay,Rear defroster timer relay,does it have a P/N on it?

Rear defroster relay. VSS Buffer. Power antenna relay. In that order.
