Installation Notes and Tips

Verify the coil connector style, terminal count, and ignition type before installation. This unit uses a 12-volt electronic HEI configuration with blade terminals, a female connector, and no mounting bracket. Confirm the vehicle’s year, make, model, and emission configuration where noted, including the 1994-1995 Toyota Camry with California Emission System application and the 1992 Toyota MR2 blade-terminal applications.

For best results, inspect related ignition components such as spark plugs, wires, and connectors during service. Confirm fitment against the vehicle’s original coil part number before installation.
