No, D16y7 uses a 4 wire heated lambda .The heated lambda is better anyway imo ,specially if you are using a lambda on the downpipe .You can find Denso first replaced 4wire lambda's on ebay ,they cost around 40-50euro and they are very good.Been using one for 2 years now.Or bosch or NTK (ngk) or oem honda they are all good.The bosch or NTK are a bit more pricy around 80euro but they have a better quality too.I would not recomend using no name lambda's ,i've had bad experience with them

@ Owen

- P06 ecu or another obd1 ecu.
- D15b7 distributor (TD41u)
- 240cc injectors obd2a (Or 240ccinjectors obd1 with obd1 plugs)
- 4wire lambda
- D16y7 engine harnas
- IACV sensor plug (obd1)
- PCS sensor plug (obd1) (in my case D16y7 ued a different style plug)
- Ecu conversion harnas obd2a to obd1.(In my case i had to repin 1 wire from the iacv cause most obd2a to obd1 harnasses are made for a D16y8)
- Distributor conversion harnas 10 pin obd2 to obd1.Or cut and solder obd1 ignition plugs yourself.

PS: PCS and IACV sensor plugs are both thesame plugs (2wires round plug) .
Aha ok thats clear, heated lambda anyway!

But what does PCS stand for?

PCS - Control solenoid, this one is for the small black cylindric valve on the back of the IM

For the OBD2a harness I should follow Joris's guide or can I buy one??

And for the distributor harness I can buy the one you showed in your earlier post??

The obd2a to obd1 ecu conversion harnasses are widely available.
Boomslang , rywire and others sell them.The distributor conversion harnas is sold only by Rywire afaik.grtz

So if I'm right the ECU plugs on a '96-'00 loom are on the engine wire loom ? As far as I know the ECU plugs on a '92-'00 loom are on the interiour loom, isn't it ?
