So im about to start my b18b swap in a week or so once im out of school, and somethin just kinda popped in my head while i was reading through another thread. It occurs to me since i'll be using my stock Si d16a6 harness on the b18b engine with the rywire conversion harness, that the clips on that harness would also have to match the obd1 injector clips of the newer motor. At this point i haven't come across anything pertaining to this swap that mentions i'd have to change or remove and replace obd0 clips with obd1 clips. So i'm lead to assume that the si harness will hook up just fine to the newer injectors. Is that right, or am i completely in the wrong here lol?

And since im already making a thread on this, i figured ill inquire about somethin else as well. my rywire harness came in today. on the subharness there is the connection for the 4 wire o2, and also a connector for i believe the coolant temperature. lastly there is a small 1 wire connector but im not sure what its for. i glanced over the side of the engine but couldnt find a connector that this would plug into. anyone know what it could be for? i can get a pic too if it would help.

 

ok well now that i got a chance to take a look at both clips in the light it would appear so far as i can tell, that they are identical.

I guess on to my next question. What does this connector go to thats off the rywire subharness? heres a pic

we have done many OBD0 to OBD1 swaps and have never changed the injector clips - just plug right in

 

not too many one wire connectors on a harness - is it for the temp gauge? on the end of the head below the distributor

 

actually the temp gauge is that two pin yellow connector on the subharness. i still dont know what the single black wire grey connector is for?

so your saying the temp gauge sensor with the one wire located on the end of the head below the distributor is where this clip is supposed to go? theres nothin on the head, or near it, that matches this silly *** connector.

I hopped on alldata to see what i could find. The ECT sensor is on the end of the head like ya said, and the wire colors are red/white, and green/blue. atleast on this b18b1 motor they are. the ECT gauge sending unit is directly next to it, and that is a one wire connection. However this connector in comparison to the one on the subharness are two totally different things. i'm still at a loss as to what this doohicky is supposed to be for.
