Plug near distributor

[Jeff Dodson]

I saw where there was a conversation about a plug with a BLACK and BROWN wire near the distributor.  What is this plug for. 

[Scott S.]

Hey Jeff, is it connected to the distributor ?

Picture of my stock 1971 350 4BBL Monte Carlo. I think this connector has one black and one brown wire. I believe it attaches to the relay looking small box just above it. I think it is part of the TCS (Transmission Controlled Spark) system, that I unhooked years ago. I think the Green wire also attaches to that relay box that doesn't have any wires attached to it.

No...

I looked on my 72. I seen black and brown but with other colors too. Post a picture of the plug.

What year is the car. A photo would help also. Then I could look it up in the wiring diagram.

[Jeff Dodson]

Wow, I'm sorry, I didn't realize I let this post go. I'll have to look back. I'm actually in the middle of Body mounts, inner fenders and AC delete.  I don't remember the wires. I'm also trying to figure out what AC wires to delete. I will be doing a Vintage Air,  much later. But I want to get rid of those wires in that firewall pass through. Can I just remove them. I don't just cut wires

Hey Jeff,

when you get a chance, post a couple pics and the year of your Monte, please.

NICE.......

Hey Jeff,

Got to thinking about the harness you're looking at and I'm wondering if it's not the windshield wiper pump wire.....

I've added a pic of harness, colours are different as it's a Chevelle one, but the ends will be the same.

Any of the ends look like what you're talking about ??

Scott.

That's a pic of a 1965 Chevelle harness though, if the Google image search is correct.

[Jeff Dodson]

Mine is a flat plug just like the flat ones in the Pic but the wire colors are Black wire and brown wire. And it's on the other side of the carborator from windshield wiper pump. 

 

I was actually wondering if it were possibly original choke wire plug ?, it's on the side...

They didn't have electric chokes back then.

Ok, back to the drawing board

[420ponies]

I have a'72 with air. I'm going to see what my assembly manual shows. Is it a 2 wire with a slide on connector? What I mean is you can see the terminals on 1 side of the connector. Very nice looking'72 you have, is that a factory color? Looks like it could be the C.E.C.valve . this was a 2 bbl set-up. Hope this helps.🙂

Like I was sayin' Jeff, the colours are different because it's from a Chevelle......  '65-'67 if I remember right. (Thanks Joe.)

But the ends are the same.

Montelishi's wires are black and brown..... And she's a '70. 

I have her wrapped up for the winter, or else I'd send you a pic.

Scott.

This is the plug I was referring to. Sorry, I finally remember to take the picture

[Scott S.]

Considering it's location, I'm thinking that it's for the TCS relay.

Transmission Controlled Spark relay.

Seeing as you've gone to an HEI distributor, these don't do anything anymore.

Where does it travel to. I'd like to remove it

[Scott S.]

The black wire runs to a ground point, and the brown runs back to the relay mounted on the firewall on the passenger's side of the distributor.

Mine was rewired for the HEI when I got it, but there are lots of Youtube videos on how and what to do with the wiring.

That's what I needed.  Thank you

That's exactly what it us, thank you, I also found the black plug that went to the transmission.  I found a couple other wires I'm trying to figure out. The double green ( solid green and green w/ white stripes ) then I found a cut Orange wire when I pulled the wrapping off the wires

[Scott S.]

I think the green ones run to the temp sender.... If they're running in the same spot.

And the only orange wire I can think of around there should be power to the heater fan. I'd have to take another look.
