99 si engine harness pnp in my 974dr

[mccoy1178]

Im puttin my ls swap in my 97 4dr n need some advice from u honda gurus. I have modified a lx harness for the b series motor (iacv 2 wire, ck sensor plug). I am using it bc it has 2 o2 connectors that I need to pass emissions. will this run the car without throwing a CEL? I am using a obd2 LS ecu too!


-can use 99si engine harness (use ob2b-obd2a jumper harness *need to pass emissions) in my 97 4dr civic with ls swap? I just want to make sure the interior harness (green plugs) will connect and power up my interior stuff like cluster, pl, pw etc....

another ?
-I need (2) o2 sensors, si engine harness only has 1. Do i need to get a si cabin harness or ex cabin harness for the 2nd o2 plug?

i would use the 97 harness. i think the 99-00 plugs are diffrent on the driverside connector and the ecu plugs are not the same
