HELP WITH! 97 obd2 ls into my 99 civic
i'm fixing to purchase a 97 LS swap for my 99 civic ex, question is will everything be plug and play? the swap comes with dizzy, alternater. starter and all that?
will all the other plugs be the same?.. someone said i'll have to rewire the CFK and the IACV.. but i have a obd2b to obd1 cabin jumper harness with a crome ecu..
will i run into any problems guys?.. also, can i use the 97 integra wiring harness? will i have any problems with me obd2B jumper harness?..
sorry i coudln't really find any threads with the same swap questions as mine, but if u guys have a link that'll help TIA!

Re: HELP WITH! 97 obd2 ls into my 99 civic (ohsnapzafingcu)
you will need to reuse the civic harness. you don't need to rewire the IACV unless the car was originally an automatic and it hasn't already been rewired. You will need to make a hybrid/custom distributor using the CYP/CKP/TDC sensors from the EX distributor in the LS distributor case due to the different plugs. You may need to rewire the CKF sensor, one is 2 wires and the other is 3 I believe, color match the wires. Use the jumper harness for the ECU.

when u talk about the different plugs on the distributor are u talking different because my car is obd2b? and the LS will be obd2a?
or does the obd2a/b even exsist on integras?

Sort of. It does in terms of the ECU plugs, but the distributor plug never changed like it did on the civics between OBD2A and OBD2B.

so if i can find a civic obd2a engine harness, it'll be basically plug and play unlike the obd2b civic harness?

So i'm going to say no, but i'm really not a big EK guy so if anyone has done this successfully, or attempted it and confirm that it wont work please chime in.

-All obd2 ditributor plugs are the same single big plug. obd1 has two plugs. obd0 has two milky plugs.
-You will need to rewire your IACV from a 3wire to a 2wire plug. And possibly extend certain plugs like map/tps/IAT. (this is if you keep your stock harness).
-You could also just go out and get an EX or SI harness and not use the vtec plugs.
-No, a 96-98 civic harness will not work.
-You'd also be better off getting a jumper and running obd1 and not worrying about cfk n secondary O2.
good luck.

Not if using the Del Sol or CRV bracket (CRV is generally cheaper)
4.94+ b series hydro clutch and flywheel
Any B series
5.94+ b series hydro tranny, and axles
Correct
6.99-00 si rear T-bracket
Correct, and you will also need the SI timing side engine mount bracket
7.94+ gsr upper and lower radiator hoses

Edit, HXs were OBD2A for all years of production, but they may have used the smaller style distributor plug.
