can i use a EX 99-00 engine wire harness to do my SI b16 swap?

 

yeah they will work, they are both obd2 b

 

anybody else? well another thing is, does the ex harness have all the wires to plug up my b16?

 

only if this harness is for an obd2b chassis

 

u should listen to crazyguy, he knows wtf hes talkin about

yes it will work

 

ok maybe i been fool and been fooling..i have a b16..0bd-1 with a gsr head 0bd-1 head but what to run a obd-2 cus my car is 2000 civic....can i still use the ex 0bd-2 harness?

^^^ do that

 

You can use the obd2b ex harness, of course... You will want to, unless you want to wire a ****-ton of stuff individually. The 2b harness is quite different from 2a and of course obd1.
Is that your current stock harness, or...?

I dont know what this guy ^ is suggesting, but if youre using a obd2 distributor and alternator you'll have no problems
(you never said which ecu though)

 

no....i have a 2000 civic hatchback DX ..non-vtec..and i will be running a chip p28

 

Ok You never said that before...
Use your stock harness and add the wires for vtec and knock sensor
be done with it - thats only a few wires...dont waste your money

get an obd2b->obd1 ecu jumper
