Alright I'm in the process of wiring up my GM 3 Bar for my AEM EMS and I've run into a problem. This will be the 5th GM map I've wired up but this hatch is different. Its a 92 Canadian model DX and the Map senor is separate from the rest of the harness, its wired directly to the ECU plugs in its own factory loom. The issue I'm having is that the colors for the Map wiring are not like any of the other 92-95 civics I've done. Rather the a Green/White-ground, white-signal, and yellow/red-5V I have a white, green, and yellow with a green stripe. I'm thinking its like most Honda OBD1 stuff and the white is power, yellow with green stripe is signal, and the green is the ground. Can somebody confirm this for me? And before it starts I've searched and the only thing I've found is the standard wiring which doesn't help me. Thanks for any input

 

use a voltmeter to be 100 percent sure.

 

I thought about that I believe with the GM 3 bar it should read 1.6v between the signal ground right?
