hello,have a 94 civic cx with a d16y7 non vtech.i wish 2 install a b16a2 SIR II.i know
they are both OBD1 but the b16 has a 4 wire o2 sensor,and vtech.I hear u can use the stock wire harness from the d16 and just add wires for vtech and o2 sensor.i have looked for diagrams on the internet,google everthing.has anyone done this swap?
the only thing im sketchey on is the wireing.but if anyone has a swap guide i would
love it.

 
A Y7 isnt OBDI and I have never heard of any Honda that had VTECH? Hondas do however have VTEC, and <5 minutes of searching would have turned up results for you.
 
well can i just buy a stock usdm wire harness.thats obd1 and add the wires i was origannly talking
talkin about?thanx n im a lil new so sry i spelled ur VTEC wrong my error.
 
stock you had a d15b8, so are you saying you have a d16y7 in there now? most likely running on the stock b8 ecu i would imagine.

this is what you need as far as wiring goes..
