Okay I think I'm gonna be pissed.

All I can figure is that out of the millions of 1720/11f0 pictures on the web, the first decent result in my original 10 second search got me a 1980/P75 picture. That means it's the middle resistor matrix, but my pic shows RM14 connections. On both 1720 and 11f0 boards RM5 is indeed the top matrix.

Okay I think I have it all mapped out. I double-checked, but would like anyone else with knowledgabilities to triple-check it.

This will effectively bypass the stock injector drivers but re-use the stock injector wires. Meaning plug and play in any Civic/Teg. IDK if the stock mosfet's *must* me removed, but I don't think so. You would lift the ecu's connector pins for the injectors and reconnect them to the jbperf v1.1 board's injector outputs. Next wire the jbperf's inputs to the spots on RM5 (again, I doubt RM5 has to be removed). Then wire in the signal ground and +5vdc power (any single spot shown should work). The stock drivers actually use the same spot to ground the injectors as they do for the signal ground, so you should be able to use the same wire for both. Otherwise just scrape off some green shit where the ground pad is anywhere around the board (make sure it's ground first!). If you have no needs for 8 injectors (4 p&h, 4 saturated/small p&h), I'd recommend just removing RM5 and using the holes for your wires to keep everything on the top-side.

After that, cut a chunk of 1/8" aluminum for the new case top and bolt the jbperf board to it using nylon spacers. Use mica insulators and nylon nuts/bolts. It's actually rather simple. I probably took more time drawing it than I will connecting it once I order one.
