I'll spare the long dumb story, but I have an 89 Civic with a 96 Integra Ls (B18b1) engine swapped in. It runs fine, but have had issues with the map sensor. I picked up the pigtails from a 97 Integra and am not exactly sure which colors correspond with the ones from the civic harness. This is a matter of me not knowing what each color coded wire means. I am replacing the map sensor connector as well as another sensor, of which I unfortunately don't know the name. From the stock harness is 5 wires the first three, white, green/ white band, and yellow/ red band go to the map sensor. The other two, black and green go to the other sensor. On the integra pigtails, the map sensor has yellow/ red band, green/ white band, and red/ green band. The other sensor has yellow/ black band and red/ yellow band. I assume the pairing is as follows:

Chassis -----> Pigtails
MAP
green/ white band -> green/ white band
yellow/ red band -> yellow/ red band
white -> red/ green band
Other sensor
black -> yellow/ black band
green -> red/ yellow band

If you know better, please let me know.
