ive read 4 or 5 different sets of instructions on wiring a vtec light. its very simple i know. positive lead to a4, 330phm resistor on negative leg, gorund to chassis.

Just wondering tho, however all the instructions say ground to chassis can i ground it to either pin b2 or a16 on my obd1 ecu? id much rather keep all the wires im running around (shift light, gauges, vtec light) kept to my conversion harness (obd0 to odb1) for the ecu.

Thanks a lot
