Like others have said rip it all out ! really pretty easy to tell whats not OEM anything zip tied on and all wires coming from it or patch on wire taps.
One of the first things I did on my 80 and my first Gen Tundra
car wont crank unless jumped, battery dying, low idling ( sometimes at 100 rpms) and then stalling, driving at 50mph and throttling and drops to 0mph

Start there and the trace all
Of the wiring to its termination points. See if you’ve got any factory connectors left. Unhook/unplug all
Of that s***. Then see where things stand.
Yup, like all said, alarm. Eventually, it will likely cause a no start, like it did for me. I had to tear one out in the parking lot, then back to business...

I think I ripped the whole alarm system out and put temporary electrical tape connecting and covering everything back to original.
but there seems to be a problem still (not totally unexpected)
I jump the truck and charge the battery a bit, the discharge light turns off but my idling is often very low it's reading 100-600 and when I disconnect the jumper cables the truck slowly but surely eventually dies. maybe its the battery? I ordered the fusible links but it will be awhile

Did you install a new battery yet? If not slap a new one in along with a new fuseable link. Without these two things being good your just pissing into the wind. If those are good I’d look into throttle position sensor / MAF sensor / IACV / temp sensor for the computer not the gauge / and throttle body cleanliness.

Air, fuel, spark.
When you buy the new battery, purchase one that is rated high for cold starts.
You’ve got the alarm pulled which is great. If it wasn’t THE problem it can’t have been helping. And you’ve diagnosed at least one failing part. New TPS is in order and you’re doing some “while I’m in there” things? Which is also in the money. But that low idle, man, I really think you need to double check the IACV. I’d add that to your parts list as well.
Getting these old trucks in good running order is frigging expensive, but absolutely worth it.
Replace the freakin battery already.
Have your alternator tested.
Replace fusible links.

I put my moms car battery in my car and tried cranking it only for a few seconds as to not kill her battery and it didn't turn over( it just kept cranking, same thing happening when I jump the bad battery ) , I already placed an order on the fusible links and am trying to buy a new battery today but don't have a car to get to an auto parts store.
