Not sure what your goal is? Do you need the components or the wiring? As far as the wiring goes, I though the TCS system was incorporated into the engine harness. Do you have an assembly manual to reference?
If you really need the components, shop around. I have seen NOS and repro Solenoids go for around $75. Check Corvette catalogs. M&H has T.C.S. Solenoids and wiring

I have also seen the TCS NOS relay 3961573 go for about $20 on ebay. Greg
