2000 4.0

Hey All, I finally got my 2000 Ranger 4.0 OHV fixed. I broke down and took it to the shop.. Turned out to be a clogged catalytic converter. The Mechanic tried his scanner (on top of my Launch, Innova, and Actron) but couldn't get communication from the ECU (is what the scanner says). It won't...

So If anyone viewing this has seen my other threads they relate to this. The previous owner cut back the old wiring harness but left five wires out, I’m wondering what they go to. Keep in mind he races trophy trucks and builds prerunners. I have an idea of what they go to but not entirely sure.

Here’s the engine and trans along with everything else that came with. I’m looking into a wiring harness but I’m having issues finding one, if anyone has access to one please let me know. Also dash and gauge cluster any recommendations on where I can get those?
