On my 70 Rallye 350 I have two connectors that aren’t hooked up to anything, does anybody know what they are for? Thanks in advance!

 

The first oneis for the TCS solenoid that originally mounted on the intake manifold. The second one would be hooked to the TCS switch on the transmission. This switch activates the solenoid on the intake. It is common for these to be unhooked and bypassed. To bypass, people would just hook a vacuum hose from the ported vacuum port to the distributor vacuum advance. They would then remove the solenoid and unhook the wiring.
