So I installed the motor and harness with the ECU onto my 99 Hatchback and now there seems to be an extra plug for the ECU and I dont kno were to put it.

Also there is no fuel going to the motor, the AUTOMATIC shift light on the dash stay's on 2nd Gear.

I need to kno were did i go wrong? I thought I had everything i needed???

 

This is the extra Plug that I dont kno were to put

It turns over but doesnt want to send fuel. We Sprayed Starting fluid and it turned so I cant seem to figure out what seems to be the problem.

PLZ HELP!!!!

 

you cant use that harness. The obd2a harness you have wired up has 3 ecu plugs. The obd2b harness, which should be in your car, has only 2 ecu plugs on the harness. The third ecu plug, is the one you have left over in the picture.

Cliffs: Get the right harness (obd2b 99-00)

 

cant i just get a computer from a 99-00 Civic EX?

 

^^ no read what he said. you cant use the harness.

 

your hatch is a 99[obd2b] and the harness u have on there with the motor is a 98[obd2a] the plugs are ddifferent.. use your stock 99 harness and u will have no problems

 

But I thought the D16Y7 Harness wouldnt work on a D16Y8 Engine?

thats why i transferred everything.....

So ur saying i will have no problems with my D16Y7 Harness?

 

you will need to rewire the IACV, and add whatever wires you need for vtec. Everything else will be the same.

 

OP doesn't need to do any wiring modifications for the IACV, the automatic Y8s use the same 3 wire IACV as all Y7s.

To the OP, either reuse your stock DX harness and add the vtec wiring, or pick up a '99 - '00 EX automatic harness and use that, you must also use an automatic '99 - '00 P2P ECU.
