Wiring harness problems.
It's for the 1985 4+3 if anyone didnt know.
I have a few connections/ vac lines I cant figure out( cut or missing connectors). I have a fairly good idea but not concrete & want to know before I get the intake & everything back on so I can route them correctly.
The 1st is a wire that runs down with the starter wiring. It is green in color & has a "crimped on" metal bracket( I say crimped because it is crushed & has some sort of anti-chafing material around the wire, so it doesnt get....chafed..doh'). I believe this goes to the knock sensor. But I dont have a knock sensor or the connector to verify this.
2nd is a vac line & connector that branches off of the starter wiring( about 2 foot ling). It is a 3 prong connector that is BROWN in color & has a vac line accompanying it. The vac line is HARD & runs across the back of the engine to a Tee that branches off to a soft line & a soft 90 deg vac line that is disconnected( unsure of what thsi goes to). The it goes to another T. That goes to the cruise control & to what I assume is the vaccum ball up to the drives side (The line disappears into a harness & when I tug on the line the vac ball moves).
3rd is IMMEDIATLY coming out of the harness next to the firewall. Is a green wire with a male bullet connector. A 2 prong male bullet connector with Grey & Pink wires respectivly. The a Oval 2 wirw female bullet connector with Pink(?) & Black wires.
Lastly for the 4+3 folks. On the OD unit there is a Black plastic tube that appears to be conformed to run up the floor & goes into the engine bay right by the distributor. Does anyone know what this connects to? It has a White plastic fitting on top that is about 1/4" think & has a + formed into teh top of ti. I dont know if a connector is missing from it or what.
I can supply pics for anything in question, if needed.
As always any help is greatly appreciated.

Well, I founf out that the 1 bullet connector hooks to the EGR wire( correct me if I am wrong pease).
The Oval female bullet goes to a square box liiokin gthing that has vac lines coming off of it. BUT I dont know where it bolts to. I assume to the Pass side cyl head on the rear. Atleast that looks like the most logical place.
Still not sure of the other connector though. I may be missing some parts...uugghh.
With the new piece( that bolts to the head) I may have figured out all the vac lines.
