Stalled then no crank

Okay. Question, is the TN/RD wire suppose to have volts if the harness is not plugged into the TRS?

Meaning I have 8+ volts no matter if the harness is attached or not on the TRS.

If the harness is not attached then where is the 8+ volts coming from on the TN/RD wire?

Ah, okay. So get a new TRS?

Okay, I will order one today.
On a side note; I plugged the old TRS back in just to see if they both had same issue.
The old one has 8+ volts on the BN/PK input wire after plugging it in. So it too is bad. Lol

Okay, call me stupid or crazy or maybe I just did not have my leads connected correctly but after putting the second (newer) TRS back in, I decided to ensure I had it adjusted perfectly with the pre-marked lines for being in neutral. Then re-tested volts at start. I now have matching 12+ volts on both the input and output at the TRS. Additionally I decided to see if it was making to PIN 85 on the relay. It does. So all three points match.

Not sure what the next step would be, lol.

Nope. :(

Relay does not click. Checked PIN86 for ground signal on start but it stays at 8+ volts.
Security light goes off when I turn the key to "on" position.

I will have to wait until tomorrow when I can get my hands on a scan tool. I will update you then. Thank you Roy! Things are beginning to look up! :)
