Default Truck wont start after swapping to 5speed.

Pretty much as the title says! I hooked everything up but there was a connector i had to cut off of the donor truck to hook on mine (the connector that goes on top of the trans. Thinking the connector is green). But im not a electrical wizard. So if i ask stuiped questions im sorry. I also noticed that the wait to start light didnt come on and the water in fuel light didnt come on either. I thinking all the other lights came on as usually. But ill keep ya'll upgraded on whats what. Thanks

Bryan

No i cant get anything to get work. Here is what it is doing. turn the key to warm it up. and the only lights that work is the brake light, airgbag, oil, seat belt and im thinking thats it. I noticed that the wait to start light,gen light didnt work. But the airdog runs like a champ and when you go farther to start it. It seems like you dont have any batteries in there. But im gonna mess around some more and see what i can find out.

Thanks cummins95! ill give it a try and keep you in touch.

Update; i found out the problem with the wait to start light. The engine fuse was in the wrong place but it still wont start but i had the computer on it. and a P0123 code came up which was the TPS voltage and come to find out that the TPS was discounnected.

I was messing around and found out that the cig. fuse was blown and i turned out my fan and it would only blow out of the defroster vents. and ive had that problem before and it was a vacuum line was disconnected but havent found anything yet.

Where is that at? Is that the connector you gotta plug up from the slave cylinder? Or is it on the top of the trans. Because im useing a 96' 5speed and the transfer case and putting it on my 97'

What did you do with the Neutral safety switch it's not going to start if you didnt override it.
