My friend has a 00 civic sedan EX and is swapping in a b16a2 motor. Can the stock harness be used off that car, or does he have to get the b16 harness for the engine? Any input would be appreciated.


Thanks

 

if anyone could provide an answer a.s.a.p. i would very much appreciate it, as time is of the essence.

 

I'm suprized no one has responded to this, I know for a fact that many people on this board have an answer to your question, but unfortunately I don't

 

i'm interested to know the answer as well because i want to do a gsr swap.

 

using the b16 harness is best.
you can use the d series harness but will need to add a few wires and some connectors are a bit different for example distributor etc...

 

doesnt that require taking out the complete wiring harness that goes all the way to the ecu?

 

doesnt what require what?

 

You obviously have no idea what your talking about, the ek's except the sir, have one harness, all connected into one, its not like the obd1 5gen where the engines have there own harness.

Its best using your d series harness since u have an ex its already prewired for vtec,

 

youre 100% right

 

your right I completely forgot about that.

 

I dont know why the eks are like that, it make so much more sense to have it like the obd1, i dont know what they where thinking.

 

the EX Sedan does not have a VTEC motor in it. D16Y7 I believe is in there.

Does that alter the situation?

ThanX.

 

so the d16y7 in the 00civic that has the non-vtec motor has a harness that is prewired for vtec even though it doesnt have a vtec motor? if this is the case, will the stock harness work on the b16a2 motor from a 00 sir?

 

i thought the ex had the d16y8 and the lx the d16y7?
Either way u sue your stock harness, and add wires.

 

Your wrong the ex has the vtec motor

"1996-2000 Honda Civic: Highlights
Subcompact front-drive Civics again came in three body styles: 2-door notchback coupe, 2-door hatchback, and 4-door sedan. Coupes and sedans were about 2.3 inches longer, whereas the hatchback grew by 4.3 inches--now riding the same wheelbase as the coupe and sedan. A 106-horsepower 4-cylinder engine powered the CX, DX, and LX, and could be accompanied by either a 5-speed manual or 4-speed automatic transmission. The HX coupe's engine makes 115 horsepower, driving either a 5-speed or the innovative new CVT (continuously variable) automatic transmission. It operates somewhat like an electrical dimmer, in contrast to a 3-way light switch. EX Civics hold a 127-horsepower engine, with either manual or automatic shift. Dual airbags were standard on all models. Antilock brakes were standard on the EX sedan, but optional on the LX sedan and EX coupe"

 

Any 6th gen CDN market sedan manufactured '99-02 came with non-vtec d16y7 engine as standard equipment(no optional engine) regardless of trim level.

the D16Y8 engine came in USDM EX sedans & coupes.
In Canada, in order to get a D16Y8 engine in a sedan bodystyle you had to purchase an Acura 1.6EL.

 

You sir, are correctamondo. only CDM Civic Si's came with the D16Y8, alongside the 1.6 EL.

 

For an OBD2 b16a into an EK, just use the factory main chassis harness then add what you need as required. In regards to the wiring be sure to solder and shrinkwrap all connections to avoid future problems.

Being an '00 sedan would mean that it would possess an OBD2b system, and you should wire the ecu pinouts accordingly. DO a little research and you should be able to find the information you require.
