So I'm lost on what these cables are. What confuses me is each of these plugs have 2 wires which have two different colors on each wires. I think one is iat sensor plug(plug broken off). I also think one is the the iacv plug. Not sure about the third one. Also I need pics to make sure I'm fixing the plugs correctly when reinserting the wires in the plugs please. I've Searched with no luck at http://technet.ff-squad.com/wiring.obd2b.htm

Here's a vid of the wires. By the way I know I need a new reservoir. Got one ordered. Need to know these plugs for my gsr swap.

Also looks like you have the wrong connector plugged into your knock sensor in the block, it only has one wire, looks like you may have the IAB plugged into it.

Thanks a lot. My gsr will b obd1 so won't need knock sensor. Good eye!

When I repair the plugs on the wires I'm not sure what side or where what hole I need to insert the wire.

OBD1 does use a knock sensor

Here's some more wires not sure of. I've tried to look at the ff squad site but I'm lost on what is what. What is the oil pressure sensor color also? It's just one wire right? Would it throw a code if not connected? Thanks for your replies so far. Excuse the loud hissing. Finally got it running today and was bleeding the coolant.

Thanks a lot! the only connectors I need to connect now are the knock sensor and oil pressure sensor. Will it hurt the engine if I dont hook it up? B18c1 obd1 engine, no crank sensor. Obd2b to obd1 jumper harness. Does the knock sensor and oil pressure sensor have 2 wires going to them?

HondaPartsHero

Knock has one. If you're referring to the VTEC oil pressure switch it has 2 wires. What Ecu are you using?

CKnight90

P28 usdm chipped. Gsr basemap. The oil sensor below the knock sensor. I read online the p28 doesn't look for a knock sensor even when chipped?

Btw...appreciate your responses

HondaPartsHero

Yeah no need to wire the knock. The oil pressure one lets you know when it's low and is what causes the oil light on the dash to work.

Ok. I'll hook the oil sensor then. Other then that I think I'm good. No cels for the first time ever! Even with it not hooked up the oil light doesn't come on though. When I pput key in the light does come on though. Btw what's a good price to sell my pr3-4 b16a2 used head?
