Hi all!

I hope that I'll be able to find some guidance here, as I'm fighting the feeling I've bitten off more than I can chew...

I have a 1999 Blazer, that ran well right up until my wife blew the head gasket. My son needed a car around that point, and was willing to give the repair job a go; I also had some friends with strong MOPAR backgrounds, and so it seemed it would be a good learning experience.

We finally got it to a point where the engine was replaced, and it even turned over! Unfortunately, the test drive failed, as the transmission wouldn't engage. We discovered that, in removing the engine, my son had stripped some of the wire harness connectors, and damaged the neutral safety switch, cracking the casing.

On the NSS, there were two wires pulled from the 4-wire connector (the black and white wire remained attached). I repaired this connection, but am not certain the remaining two wires are correctly aligned. I can't find a wiring diagram to tell me which way they go.

On a wire harness cable descending from the top of the bell housing, roughly in line with the NSS, there is another 6-pin connector, with 5-wires leading into it (black/white/light gray/green/purple). This pretty inaccessible wire had the connector ripped off. I've soldered extension wires into a replacement connector, and used the mating connector to determine where the connections went. I'm pretty sure I got those right.

I installed the new NSS, and connected everything together. However, now the car no longer cranks. The check engine light came on, though. Also, I heard a minor clicking noise (a relay?) after trying; that didn't stop even when I pulled the key. I disconnected all three wire connectors, and discovered that something was off with the electrical system. The power locks no longer function, nor does the radio or lights. The engine no longer cranks.

I guess the main question is, how bad is this? Is there enough information to try and work out a repair plan? Is this something I can do? Any experienced samaritans in the Bowling Green, KY area? If I have to take it to a professional, any thoughts on the rough costs?

On an unrelated note, is there a place where I can sell the old, uncracked core to get some money for a professional to look at this?

Thanks for all your help!
