Electro-magnetic multiplex demodulator for the 64-megahertz sound wave generator circuit and its counter part for the forward light duplicating night guidance system. Also know in some parts of this world as a horn and/or head light relay....or none of these....I dont think I'm helping in any way so I must say goodnight

Transmission Controlled Spark. The relay controls power to the vacuum solenoid on the right side of the intake manifold by the carb.

Were they on the inside or under the hood? If under the dash on the firewall, it's a horn relay.
If on the firewall under the hood.....well, I still haven't figured that one out yet. On my 70 K10, it had one ignition-on wire running to it (pink), and 4 wires running out. Two went to an A/C compressor type connector (blue/black), one red with a spade, and I can't remember the other one. Regardless, the thing had only one input wire to it, the pinkl one. And that was originally tapped off of the radio power wire.

So on a new wiring harness are these part of the system still or do you unbolt and throw these items away? Glock bot units are inside the cab..

They are th transister control spark relays- when you order your new harness you need to specify if you want to keep it (depends on if the solinoid is still attached to the pass. side intake manifold. It should have a plug that looks like A/c plug -2 flats and nipplies for vaccumn on each end. Hope this helps.

I swapped in a 454-th400 combo and will order a new harness for that set-up from what I understand I can remove and throw away these two items correct?
