Default TCC relay location?

Ok guys, I have an 87 coupe and need some help/ideas as to where to TCC relay could be. I thought it was supposed to be right next to the fuel pump relay next to the booster on a bracket. But, I cant seem to find it or the harness that comes up to it. My lockup function isnt working and i dont have power to the trans with the key on so i was trying to find the relay to check it as well.

No relay
Power goes through brake switch to TCC solenoid then is grounded back at ECM
Check brake switch is not open when brake off

I knocked my TCC pedal switch out of adjustment during a brake booster replacement.

A second relay next to the fuel pump relay on firewall would only be there for the overdrive on manual trans. Autos only have the fuel pump relay there.
