86 (FI 4cyl) that has been swapped to an older model carbed 302. Sensors on the engine that are monitored by the EEC are no longer there. Can I remove the EEC or is ALL the cars electronics ran through it (Guages, headlights, etc.)
Only the engine and transmission are monitored and controlled be the EEC. You can remove it as it has nothing to do with your gauges or headlights or anything other than the engine.
That's why they named it EEC. Electronic Engine Control.
