Before I say anything... yes i know this post is really long i apologize...yes i searched I couldn't find answers... if your going to make fun of me for not finding the answers or whatever reasons some of you guys find reasons to mock people I ask that you would exercise your right to press the back button and ignore this thread and I thank you in advance for not wasting my time and your own... For those of you who are willing to help me I thank you in advance.... much more sincerely then i thank those who simply pressed the back button So i have a 93 ex with a b16 the previous owner installed. Its not ready to drive yet but i have been going through trying to check his work I have many questions especially related to the engine wiring harness and the ecu i know the ecu is stock and i assume the wiring harness is as well. I know there are multiple sensors that the b16 has that the D16 didn't and a couple that the D16 had that the B16 doesn't. I have basically no knowledge on how a swap like this would normally be done but from what I can see some pretty important things may have been overlooked. BTW if any one who is experienced with this swap would be willing to talk to me over the phone i could pm you my number because i have a lot of questions, i would really appreciate that. After cross referencing wiring diagrams for both the engine wiring harness and the engine this is what I have learned, the following sensors or switches which are on the b16 were not on the d16, Crankshaft Seed Fluctuation, Power Steering Pressure Switch, HO2S Sensor, Knock Sensor, VTEC Solenoid Valve, and VTEC Pressure Switch I may have overlooked some or not realized that it is just under a different name. Here is what was on the D16 but not the B16, Oil pressure Switch B, Spool Solenoid Valve, TDC/Crank/CYL. How do these differences affect the ecu/engine. After looking at what I have connected and what I don't this is what I found, 1. Purge Control Solenoid Valve does not seem to be on the engine but the harness is there 2.The Oil Pressure Switch A is connected but the wire just goes to a ground?What?, 3.The TDC/Crank/CYl Sensor is there connected to the engine even though the b16 doesn't have that. can someone tell me what that is, how that works 4.I don't see the Spool Solenoid harness which I would assume should be disconnected since the b16 doesn't have that, I do have a blue wire that comes out of the same conduit as the coolant temperature sending unit, that is the only single wire that i don't know what its for 5.the only plugs on the engine that i can see that don't have a plug plugged (wow I don't know how to word that without sounding stupid) into them is the knock sensor, VTEC Sensor and VTEC Solenoid Valve, I would think I would see more. 6. I don't see wires for the oil pressure switch B Okay Hopefully I haven't forgot anything, if there are some good links that will help me out could you post them I looked haven't found anything to answer my specific questions. I was told that I may want to get a different ecu that will read all the sensors (like Knock etc.) Although i do know i should be able to connect wires to the ecu for vtec. Where can I find the ecu plug information as to what each socket is for. Any suggestions are appreciated. If you want pics say what you want to see and ill post them asap.

 

Did he use the oem harness off the d16

 

Pm me ur # and i cantalk u though it cuz i used my oem harness when i put an ls into my and its not a v-tec and it works w no check engine light or anything

 

You can use a Type R harness and a P30 ecu from a Del Sol VTEC

 

thanks for the replies, im not sure think he used the oem when i looked at the wiring diagram in the service manual for the 93 everything seemed to match up except for a few things it looks like he removed ... btw twiz im sendin a pm right now

 

ok got a question, where were you looking up the b16 specs, i know OBDII b16's have the crank sensor plug by the crank pulley, as for the rest of the plugs, the only thing you should have to do is wire the vtec pressure, and vtec solenoid, (3 wires) as for that you dont need anything ealse.

 

okay thanks p12 the specs i found were out of the honda service manual
