Unknown wiring and electrical components
 

I have a 71 c-10 that I am currently redoing... this is my first full restoration. I have two electrical components and associated wiring mounted on the firewall that I have no idea what it is or what it does. The wiring runs to nothing and I can't find any info on what it may be. Here is a picture of the installation. They are mounted on the firewall just to the right (forward looking aft) of the brake booster and main harness feed through.

i took all that out about a week ago while i was cleaning up underhood wireing seems i read that it was something to do with emissions? not sure

Re: Unknown wiring and electrical components
 

That is part of the TCS emissions system, (TCS, Transmission Controlled Spark). The vacuum advance on the distributor was controlled such that it would not advance unless the engine temperature was warmed up to a set value and the transmission was in high gear.
