Yes, this would hook to the old HEI wire.
The next wire is blue that goes to BCM which I'm not using
This is an interesting harness, not sure why they would include this wire, but like you say, just leave it alone.

The next is #26 purple, "starter trigger - send to battery positive to the wire only when you want the starter to turn over the engine. This is usually goes to your ignition switch in the start position or a push button start button. This is not the same as the large gauge wire that goes from the battery to the starter and alternator" This is the wire, I think, that is my original purple wire. I tie this harness wire to my original purple wire then to the third post on the solenoid. Yes, hook your original purple starter wire to this wire and then plug the other end into the starter and you should be good to go. It appears that this is just a wire to the starter and doesn't go through the starter relay though. If you have an ohm meter and can test the continuity of the wire from the 26 spot to the 28, that would tell you for sure.
The last wire on top goes to the TCC which I have read up on and feel good about. Pretty simple on a GenIV, just needs power when the brakes are applied, the opposite of a GenIII.
Thanks for your help ls1, I really appreciate it.
