Lower T-Map wiring issue

Lower T-Map wiring issue
Hi guys, looking for some wiring advice. Lower T-Map wiring.
Well, the Stage 1 wires (installed in 2010) on the lower T-Map are worn in places and right near the plug too. Suggestions on how to replace/resolve?
Check out the T-Map bolt too.....condensation. So imagine the moisture that sits on the bare wires at times. So those that have weird running problems........ I am thinking of getting the ZZP cold IC-Throttle body pipe, to move this sensor to a safer location. (I did remove black tape they put on the set of wires, but there was still exposed wiring)
Car Specs:
178K on the body. 15K on the LDK. Hahn hot pipes, Forge bypass, few other items such as catless ZZP DP, solid engine mount and rear swaybar. WI resident.
How I finally got to here: I had the bank one code, but when cleaning the MAF, it went away for a few days. So I had replaced the MAF and first O2 sensor, second dialed out. First O2 sensor was really corroded.
Car ran great for a while. Then I would at times get the too rich at idle code, weeks apart. Sometimes the turbo circuit A code. Cleaned the MAF and replaced the upper T-Map...things ran great again.
No codes recently, but odd 0 to 5 PSI boost surge, when cruising etc. Then very recently, at times could see vac readings odd, instead of -20/30 when off the gas, creeping up to -5/-10 or so. Then car started running rough, but no codes the other day. Parked it and figured maybe maybe small boost leak or lower T-Map.
Everything appeared fine when checking connections, wanted to replace the stock IC, as I have recently replaced the MAF sensor, boost solenoid, and upper T-Map. Ordered the ZZP IC as it was something I had wanted to replace for a while, and had a lower T-Map to install yet. Re-checked the upper T-Map, and it had a small wear in the gasket, so that could account for the recent VAC issue. When installing the IC and removing the lower T-Map, found the wiring and bolt issues. Lower T-Map gasket looked ok, but I ordered a 50 pack and will be putting in new ones.

First read this TSB post #33 https://www.chevyhhr.net/forums/hhr-...g-issue-59421/
Then set about soldering & shrink wrapping all of those crimp connections.

On the plug....can I get a replacement one with the four wires easily?

Do you sell the harness separately?
