ok so i bought a 96 civic ex with a d16y5 with a y8 head and p2p ecu im having some issues with the car running. It bogs real real bad when i try driving it and there are some harness issues there are two plugs that i cant figure out what they go to(please look at pic below)
Also what do i need to get a y8 head running on a y5 block,as in what other things do i need in order to make it run like which wire harness do i use im,tb,distributor things like that?also how can i tell if i have the right wiring harness?



The two wires circled in red are the ones i cant figure out what they go to and the one circled in green is going to the distributor is it only supposed to be one connection for it

Distributor is correct. small plug at the back looks like EG-R valve (only the Y5 manifold has one so theres nothing for it to plug into. Other plug looks like Y5/Z1 5 wire O2 sensor. convert to a 4 pin plug and use a regular 4 wire O2 sensor.

the plug in the back has 5 wires the one in the front has 7 so the one in the back would be the 02 sensor?

Front is an O2 sensor, my mistake though, it is 7 wire, the older VX wideband O2 sensors were 5 wire.

so i have to convert the 7 wire into a 4 wire?and i how would i go about doing that?
