I purchased this module and found that my TPI Camaro uses a 7 pin module. This is a 4 pin module. Brand new, never installed yet I cannot return the unit. Compare to Accel 35361, this is made by CRT Performance. Comes with silicone compound. Compatible with ALL 4 pin GM 6 & 8 cyl distributors. Phone calls only to Randy @ .

　　Made In the USA, this module utilizes exacting "dwell controller" to ensure excellent spark energy to the plug that will maintain that level up to 7500 rpm. The "current controller" feature protects against coil overheating. Protected from all EMI and RFI sources.

　　Designed to fit most stock and modified GM HEI distributors. These modules feature solid state electronics to provide high coil output and superior reliability. A dwell control circuit ensures long, consistent coil charging. These modules resist false triggering from the RFI of high output coils. Made In U.S.A.!
