Schonye sent me some photos of his original survivor SY Deuce (color of this lil fellow ==>

) and showed this Deuce-nube how the TCS wire for the TCS block switch is actually routed from the passenger side back over to the driver's side. It was plugged into a factory extension wire (L-shaped connector) to get it over to the block hole between the front 2 plugs on the driver's side. As Marlin mentioned this plug was both for the TCS system AND the idiot light in the dash. I can post pix later tonite when I get home. It kind of surprises me that this is yet another Deuce LT1 difference from a Z28 LT1 (wonder what 'vette LT1 did

?). The sender/switch hole on the driver's side (betw 1st two cylinders) is encumbered on my Deuce (as is Schonye's) to accomodate my aftermarket (SW) water temp gauge sender that the Roof's installed.
So, FWIW, I will set up my TCS block switch the same way as the Z boys do (passenger side), due to my aftermarket gauge configuration.
Always an education
