These are identical to the ones off the Typhoon and Syclone just off of a GTP instead. I don't have pigtails but I am sure you can still get them from GM. Price is 30 bucks for the BCS, these are used and off cars that didn't need them. I have 6 of them.
No its a BCS on the GTP, it works as a baby sitter for the boost on the superchargers most guys take them off ... thats why I have them. The mounting bracket is different but it is a 3 port boost control solenoid. They only use the two ports though.
Bump?? Also I have hooked one up to my car with the same exact ports I have now and it acted the exact same.
