Vacuum and Electrical

[Anonymous]

Got my new (salvage) motor in and it fired up on the first turn of the key! Unfortunately, it only ran about 15 secs. and quit. Turned out to be the cam gear on the distributor. spun the roll pin. fixing that tomorrow.

Need help on the vacuum lines and 1 electrical connector . The connector comes from the ECM from the the same group that feeds the coil. I think it's for the choke? Any other place it might go? [http://i103.photobucket.com/albums/m150/sargentrs/000_1003.jpg]

There are 3 vacuum connectors on the carb that I can't remember how they go. Top one is comes right out of the throttle bowl. #1 is in the center of the carb body (behind that vacuum diaphragm). #2 is at the bottom of the carb and angles off toward the front of the engine. I've got two places to get vacuum, a tree on the manifold (#5), the hard line goes to the brake booster and 3 ports on the the vacuum switch on the thermostat housing. What should feed to where? There's 2 more lines that need/supply vacuum, I think. One from the firewall (#4), pass. side, and one from under the the exhaust mani (#3). The one from the firewall starts out as a hard plastic line and ends in about 6 inches of rubber line. The one under the mani. is steel and ends in 6 inches of rubber.

No, that would be for the "Anti-diesel throttle speed positioner" or TSP.
The choke gets hooked up to a wire that should probably be coming from the alternator.

That would be your egr vacuum pick-up tube. On mine I think it goes to the PVS.

#2 is at the bottom of the carb and angles off toward the front of the engine.

Spark vacuum port. On mine it gets split and one line goes to the distributor and the other to the charcoal cannister.

Can't help with that stuff.

The one from the firewall starts out as a hard plastic line and ends in about 6 inches of rubber line.

Probably goes to a manifold fitting.

The one under the mani. is steel and ends in 6 inches of rubber.

That goes to the tube on the top of the carb that points down at a funny angle.
What year engine and car is this?
Do you A/C?
There is also a port on the driver side of the carb. This might go to some type WOT throttle system for the EGR.
You also might have another spot on a manifold fitting to go up to a thermostat thing on the bottom of the air cleaner.

sorry, what engine would probably help wouldn't it? It's a 200ci in a '79 mustang. I've trashed all the smog control stuff, including the EGR, and the a/c too. Bare bones. The carb is a Holley #1946. The TSP didn't make the swap. Is it really necessary? #1 probably not needed then? #2 to the vacuum advance on the dist. Firewall hose to the tree. Mani. hose to the throttle bore. Tree to bottom of air cleaner. Everything else gets plugged or capped. Right? I've already capped the driver side port.

Got it! Thanks. She runs like a top! Just gotta finish setting the timing and carb, hook up the exhaust and find a snap ring for the trans. kickdown and I'm rolling. I really appreciate everybody's help and advice on this. I'll be sure and put some pics up. Thanks, again!
