OK b16a1 swap into 90 integra ls... ive found the 4 extra vtec wires, ive got my ecu pins, got the pin outs on the ecu.... the thing is that out of the 4 sensors im supposed to have for vtec 2 of them have 2 wires each. i need some help... the one sensor is black and blue wires, the other is green and red w/ yellow stripe. am i supposed to splice the 2 wires on each sensor into 1 wire going into my computer or what?????? im lost

 

Each of those 'sensors' has another wire that goes somewhere else, not to the ECM.

I don't have a '90, but it'll be something like this...
The knock sensor has a shielded wire, the shield connects to ground.
The VTEC pressure switch has a 2nd wire that goes to ground (black?)
The IAB control valve (for secondary intake) has a 2nd wire where it gets power from the main relay...

Sounds like you need a wiring diagram.
