Abstract

A modular interactive connector unit is provided which has a base block with an array of male pins on one side and opposed female pins on the other side for interconnection between an electronic control assembly for an automotive engine and a wiring harness otherwise intended for direct connection to the electronic control assembly. The base block contains an array of contact points and adapter points which correspond with the control circuits in the electronic control assembly. Circuit completing electrical adapters from the adapter arrays on the base member support a board element having spaced apart arrays of adapter points for insertion of a circuit altering device in selected control circuits. A cap protects the board elements. The circuit altering devices alter the voltages read by the electronic control assembly to enhance performance of an engine. The modular unit may be removed and the wiring harness connected directly to the electronic control assembly to return the control circuits to their factory settings.
