If still unsure, you can measure for continuity at connectors on the Emissions harness ..
The attached diagram shows connector pinouts with wires facing away from the viewer and ECU locating pins along the connector top. The injector terminal will always be the one on the right, with connector assembly facing up.
If still unsure of 26 pin connector orientation, measure for ground on 3 shown left terminals to 1 of 2 large ground eyelets on the harness, or car chassis if harness is installed.
(not to the smaller ECU chassis ground eyelet) .
I use straightened small paper clips wrapped around multitester probe tips to insert into connector terminals.
You can measure with the harness installed, by extending 1 probe lead with a jumper cable or spare wire.
