Need Help - 1999 Ford F53 Chassis Wiring

I need to find someone that has a Class A built on a 1999 Ford F53 chassis that will let me view the wiring from the Incoming Air Temperature (IAT)sensor to wherever it connects with the main wiring harness.

Mice chewed the wire into about 6" from the IAT sensor and I cannot find where to splice in a new connection.

If you live within a 100 miles of Fayetteville, AR. I would be happy to come and look at your motor home wiring.

This is not a scam and I am not a predator of any type.

I have searched online, spent money on a CD for 2000 F53 with drawings, etc. and cannot find where this wire enters the main wiring harness. The 2000 F53 IAT and MAF sensors are integrated into 1 unit. The 1999 F53 IAT and MAF sensors are separate units.

Thanks if you can help.

Wires are grey and grey w/red stripe. I will run down the MAF wire. Good thought - thanks.

Two wires. I'll get color when I get home.

Mice left about 6-8" that connects to the sensor but I cannot find loose wire on any wiring harness close by. I know the main wire eventually goes to pin 39 on the PCM. I just don't want to remove the shield from that harness wire bundle.
