yes. You'll need to add in the EGR valve wiring too.

hey I got a PM from you and I can't respond so here is my response:

Hi, sorry I didn't respond until now...

I made the jumper harness using a standard 8-pin honda engine harness plug (female) and a 4-pin O2 sensor Male plug for getting wires from the factory harness. your real LAF sensor has a variable resistor in the plug so it uses 7 pins to connect to the engine harness (including the 5 wires that go to the O2 sensor)

you can use your factory harness and ECU as long as you use the 4-wire O2 to get things running, thats exactly what I did before adding my subharness. this harness will go to the EGR, 5-wire O2 supplemental wires, as well as the EGR control box (you can harvest some parts out of I think 92-94 accords if you don't have the D15Z1 black box)

I hope this helps, if you have remaining questions feel free to ask! you can also email me directly at aaronhume@hotmail.com

Good Luck!

-Aaron
