Hey guys,
Trying to get all my connections right on my new wiring harness.  Here's the one's I'm having problems with. Can anyone identify where these go? I have included a picture of where they split off.



What are these two black wires for?


I'm assuming this is for my blower motor?



ALSO: Where does the fusible link connect to from the starter relay?

Thanks!
Paul

black rubber "cup" shape plug--------- Brake Dist block/prop valve

Brown wire spade terminal----------------windshield washer motor

Black wire splice spade terminal----------- is just a propper function check in source for the brake warning signal on cluster, goes to nowhere. Grounding that terminal should turn on the brake light on cluster

Blue wire splice spade terminal------------- source to electric choke control unit. Not the manifold coil really, is this unit control on pic ( or similar depending on year adn equipment ):



From THIS unit then is feeded the manifold choke coil unit. Is a voltage control unit according with engine bay temp to keep more or less time the choke IN by electric heating assistance

On some carbs, feeds directly the choke unit mounted on carb

What should my blower motor plug into? There's a green wire coming off of that. Also, the fusible link, does that go from the starter relay to the forward light harness or engine harness? Thanks for your help with this!

OOOPS Forgot to tell about the fuse link...

fuse link goes in to a red heavy gauge wire on FORWARD HEADLIGHT harnesss plug

Blower motor goes on one of the empty cavities of bulkhead plugs. On 71, A/C wires ( blower, green, and comp clutch, blue  ) they where both on tranny harness plug to run both together from same area. On 72/73 ( also on 74 ) models tranny harness got a new wire in to cab, so A/C harness terminals are on the only two cavities available for 72/73, and they were one on tranny and the other one on Engine harness ( if no tach equipped ).

I don't remember which one run on wich cavity. To be sure, check down the dash, on back of bulkhead to check where arrives the blower green wire, if in engine harness section, or tranny section

on 74 we got another wiring change but that's another story

probably gas pressure check valve switch on A/C dryer. Test gas on A/C system and won't allow to turn on A/C compressor if there is no gas
