Well, old motor and trans is out.

Stupid harbor freight being sold out of trans jacks... had to figure it out with a normal floor jack. Going to need one for reinstall.
I’m looking at the existing wiring in the truck, planning on my gauge hookups. I’m a little confused on some of the stuff I’m reading.
1. Oil pressure. My truck had a 1 wire hookup, and the new motor also has a 1 wire sensor on the back of the block. I see a lot of people swapping sensors and needing adapters... why? Are these providing different signals?
2. TCC lockup. I currently have a blue wire coming out of the firewall that used to go to the old th350 wiring, and it provides hot 12v until I press the brake. It seems like this is exactly what I need for the pcm, yet I see people all the time talking about splicing in relays. Will this not work?
