TheBMan Posted November 25, 2020 Share Posted November 25, 2020 Hello and thanks for having me! Recently purchased a numbers matching 72 Monte in very good condition. I'm trying to get it back to 100% original and functional. Trying to figure out what this part is. Mounted on intake manifold, next to Quadrajet carb. One vacuum line going to charcoal canister. Electrical connector was not/is not plugged in. Has two other vacuum ports that are capped. Can anyone tell me what it is/does and what the capped ports are for? Thanks!

Canuck Posted November 26, 2020 Share Posted November 26, 2020 TCS -Transmission Controlled Spark. It is common for this to be missing. There should be a vacuum line coming from the front of the carb to the solenoid. Then one from the solenoid to the vacuum advance on the distributor. There’s an electrical connection too coming from the firewall. 1 Quote Link to comment Share on other sites More sharing options...
TheBMan Posted November 28, 2020 Author Share Posted November 28, 2020 @Canuck - Thanks. Yes, after I posted I continued to research and found exactly what you said. I do have the electrical connector although it was unplugged (you can see it if you look closely at the picture). I understand why it's used and although I see it as purely an emission-related device, the car is a numbers-matching car and I'm trying to keep the car 100% original so I'll test it to make sure everything works and then hook it back up. Thank you very much! 1 Quote Link to comment Share on other sites More sharing options...

It's pretty nice now but I want to get it just right. 🙂 Quote Link to comment Share on other sites More sharing options...

cny first gen 71 Posted November 30, 2020 Share Posted November 30, 2020 That's true, if I waited to take or post pictures of mine until its perfect I'd never be able to it'll probably never be perfect I'll will always be doing something to it.
