Emissions Override Relay Wiring?

I picked up a '86 Chevrolet C30 CCDRW with a 454. The PO did a number on the wiring harness, so I pulled the engine harness and am in the processing of cleaning it up.

What I have left is wiring for 2 modules that I am trying to determine what they are (included pictures below). The numbers off the modules are:

14094774


14087500


After some research I am thinking the 14087500 is an "Emissions override relay" and the 14094774 is an "Electronic brake control" relay.
Are either one of these accurate?

Also, I am in the process of cleaning up the wiring to them and for module 14087500 it has a 5-wire weatherpack connector where in my case
- Yellow and brown wires have been cut
- Black wire has been crimped together with the other black wire from the other module for a ground.
- White wire runs to the plug that goes into the HEI distributor
- Pink wire runs into the other module connector.




Does anyone know what any of these plugs do and if I can re-wire the harness to remove one or both? Thanks for all the help.
