There is no ETC plug to deal with on the 2.6. There is, however, a vacuum line you need to plug. It goes from the VSV to the charcoal canister purge valve.

With that plugged and the idle set to 900RPM, you should time the engine to 12*BTDC. If your timing light is adjustable, either set the knob to 0* and time the pointer to 12* on the balancer or set the knob to 12* and time to pointer to 0* on the balancer.
