help identify relays
Can someone please help me identify the relays on the pictures?
I can't find them under those part numbers from AIM on any site (only NOS available). The one pointed with green arrow is power window circuit breaker?
The thing is that my car is a 71 with a TH400. I don't have any of the sensors and carburetor solenoids on my car. The only things left are kickdown switch on the gas pedal.
Are these relays neccessary for everything to work?

TCS stands for transmission controlled spark. it is an emissions system designed to provide vacuum advance only when the transmission is in high gear. Unless you want them for originality there is no need for them.

yes the th400 uses the kickdown on the gas pedal in conjunction with the vacuum modulator to control gear shifting.

what exactly do you mean by "everything"? How is the vacuum advance hose on your distributor connected, directly to the intake manifold or carburetor?
