The guage for North American models will be one of the following part numbers: '86.5 to '88 83246-14690 or 83246-14790; '89+ 83246-14890 or 83246-14870 These should all interchange without issue.
The oil pressure signal branches at connector M1. See the here. I don't have a pre89 TEWD handy for reference and I'm not finding it in my MAFT Pro wiring diagrams I made for the pre89 7M-GTE... So it's possible it's mislabeled, one of the unidentified pins or that the pre89 GTE didn't use use that signal. Look for a yellow wire with a black stripe on the ECU's connectors.
