Continued adventures with gauges and all the ancillary crap that goes on with these things.

Having cleaned grounds and added a couple I started pulling out old gauges. All the ISS[not}PRO stuff is out.
The CTS sender is working (OBDII Scan Tool indicates it is seeing the engine coolant temperature) but the OEM gauge in the instrument cluster isn't so I'll pull that and check connectivity etc.
To replace the EGT gauge sender, the fitting in the crossover wasn't budging with a wrench and the wrench was starting to round off the fitting. So I pulled the cross over to get at things better and was able to remove the sender without damage and then the fitting came out with a socket. Whew, thought I was going to have to use my old crossover or drill out the old fitting and chip out the remaining threads like that hot water bung at the T-Stat housing. Since there some discussion as to the effect of wrapping the crossover and it now being subject to rusting I unwrapped one side to see how things were looking under the stuff.
Wrapped
Unwrapped.

No issues after 5 years and 30K miles. Only rust is from the clamp crimping the two halves together being in direct contact with the pipe and that is very light and cleaned up with some steel-wool and elbow grease. I live in the high desert but, the truck is parked outside and we do get snow. The pipe was sourced through Heath Diesel. I never got him to tell me his source for the exhaust system but, it isn't whatever brand folks tend to recommend here.
One issue with the wrap is the clearances for the bolts to exhaust manifold suffer, even with studs and wrestling the crossover off the studs on the passenger side is further complicated by the down pipe being wrapped too. One can get the nuts off but, the socket is a pain on a couple of the nuts. I had other issues but, it stemmed from using studs so it won't apply to the majority here. I don't have a picture and I want to spare ya'll the '1000 words' that probably won't make any sense.
