I recently did an engine swap in my '88 camaro (305 TBI/350 TPI) and now I have no voltage to the field wire going into the alt. Where should I start looking for problems? Also where does that wire go to? The firewall connector or the ECM? Any ideas would give me a start. Thanks guys.

well my friend you have the same problem I did !!!! me it was 4 alternators and 3 batteries before I found out how an alternator was working, try this: connect the big reg wire from the back of the alternator to the battery but not directly to the battery connector, plug it on the ceramic distribution unit in front of the battery. now take the old plug from your old alternator that came with your original motor there's a green or brown wire and also a red wire.
The green or brown wire needs to be connected to the ignition in the fuse box or near that , check with a test light for pink wires when key is turned to "ON", light should be ON. check near the left side kick panel there should be a 4 pin connector witch is not plugged and there should be a big pink wire on that connector, plug this with the green or brown wire and make sure it's not in the way because you'll yank it with your feet while drive (happened to me!).

the red wire should connect to your starter's "+" connection via a fusable link.

this should solve your problem, it did for me after spending 2 days changing alternators & batteries
